[fixed]
- sf.net #881: C backend: support for varadic function parameters in gcc using __builtin_va_list type and related macros
- push/pop correct GL_PROJECTION matrix and GL_MODELVIEW matrix when setting up graphics screen (gothon)
- fix char & wchar concatentation.  For char double byte characters (such as Chinese characters), the "wstr = char & wchar" would become "wstr = char & chrw(0) & wchar" (SkyFish)
- github #131: Fix fbc makefile bootstrap recipe race condition (William Breathitt Gray)
- sf.net #794: literal tabs in string literals miscompiled if followed by 0-9 numeric chars

- SELECT CASE AS CONST checks for ranges that would produce unreasonably large jump tables (greater than 8192 entries)
- sf.net #907: global overloaded operator procs need "_Z" mangling prefix


Version 1.06.0

[changed]
- Name mangling of Integer/Long parameters was reversed on 32bit to match 64bit, so the same FB and C++ code will be compatible on both 32bit and 64bit. Integer is mangled as C++ long (except on Win64), Long is mangled as C++ int.
- Adjusted warning text for "mixed bool/nonbool operands" warning
- test-suite uses libfbcunit for unit testing framework
- SELECT CASE AS CONST respects data type and will show overflow warnings on out-of-range constants
- boolean: don't allow NEG unary op '-' on boolean data types
- All fb RTL functions are checked for CONSTness, CONST qualifiers added to fb rtlib built-in prototypes (sf.net #727)
- WSTRING can be a return type, but only for prototypes (DECLARE) and function pointers, this allows getting PROCPTR() of all fb built-in run time functions
- multiline comments are parsed in -lang fblite|qb|deprecated as in -lang fb for consistency

[added]
- Name mangling of Long parameters on Win64 are mangled to C++ int by default and to C++ long with a modifier in the form 'as [u]long alias "long"'.  The data type size is still 32bit but allows calling external C++ library expecting a C++ long.
- -noobjinfo option to disable the writing/reading of compile-time library and other linking options from/to .o and .a files. This also disables the use of fbextra.x (the supplemental linker script) for discarding the .fbctinf sections, which is useful when using the gold linker that doesn't support this kind of linker script.
- Linux console Inkey() now recognizes F11 and F12
- 2D render through OpenGL on Windows and Linux via screencontrol (angros47)
- Windows API binding updated to additionally support _WIN32_WINNT &h0501, &h0600, &h0601
- Under X11, ScreenControl GET_WINDOW_HANDLE places the Display ptr in param2
- Updated bindings: SDL2 2.0.6, SDL2_image 2.0.1, SDL2_mixer 2.0.1, SDL2_net 2.0.1, SDL2_ttf 2.0.14
- allow overload operator SQR()
- allow [static] shared byref variables to be initialized with byref variable
- warning '-w constness' to enable 'CONST qualifier discarded' warning on command line
- #pragma constness to enable/disable 'CONST qualifier discarded' warning in source code

[fixed]
- win/d3dx9.bi no longer has a hard-coded #inclib "d3dx9d". d3dx9d.dll is apparently not a generally valid choice. In practice programs have to be linked against d3dx9_33.dll or d3dx9_39.dll, etc.
- #816: The ASM backend contained a bad assert() which could be triggered in debug builds of the compiler, when generating code for certain array accesses
- C backend: undefined behaviour (inherited from C) in case of signed integer overflow
- C backend: undefined behaviour (inherited from C) in case of SHL/SHR operations with a shift amount >= the bitsize of the shifted operand in bits (if the shift amount wasn't a compile-time constant)
- utf_conv.bi: When given a NULL destination buffer, no-op conversions (UTF16 => UTF16 or UTF32 => UTF32) didn't allocate a new buffer, but just returned the source buffer, violating the contract used for proper conversions (which allocate a new buffer if a NULL destination is passed).
- utf_conv.bi: In UTF8 => UTF16/32 and UTF32 => UTF16 conversions, strings longer than 8 chars could be truncated
- #797: False-positive warnings when mixing booleans with comparisons in logic operations
- TRE binding: Didn't compile with TRE_USE_SYSTEM_REGEX_H
- LLVM backend: Emit the new (LLVM 3.7+) load-syntax
- When compiling .rc files with windres instead of GoRC (happens with non-standalone fbc), the current directory is now an include search directory, to match the GoRC behaviour.
- #659: Keep the stack 16-byte aligned on linux-x86 and darwin-x86 to comply with ABI; fixes crashes when external libraries use SSE
- On Windows, FB console input treated multiple repeated keypresses that were merged into one event by the system as a single keypress
- Accesses to 64bit bitfields could be miscompiled or trigger a compiler crash
- #732: Virtual destructors couldn't be called on const objects
- #790: Windows API and X11 bindings: Fixed some macros where macro parameters conflicted with other identifiers or FB keywords used in the macro body
- boolean initializer values for global or static variables were not emitted properly
- Compiler crash after reporting error about REDIM on a fixed-size array field
- #827: Using the GNU gold linker (instead of ld.bfd) resulted in broken binaries due to fbextra.x, which fbc uses with ld.bfd to discard the objinfo .fbctinf sections, but is not supported by gold. Now when gold is detected, fbextra.x won't be used anymore, in order to get working binaries.
- exec() on Linux & co was broken with regards to spaces in the executable path. Spaces were converted to "\ " and then to "/ ", resulting in a different path than given.
- ASM backend: Fixed a compiler crash or potentially bad code generation in complex floating point expressions (which had enough operands to use up the x86 FPU stack, and trigger spilling of st() registers to stack)
- C backend: Pointer arithmetic on the address of variables with any pointer type gave wrong results due to bad code generation in -gen gcc for this case.
- LLVM backend: Self-BOP emitting, byref var/param accesses
- #837: Compiler hang (or assertion triggered, if enabled) for Select Case As Const with Case -1
- ASM backend: Invalid code generated for Select Case As Const jump table index when 64bit fbc cross-compiles to 32bit
- #836: The MyUdt() syntax for creating temporary objects allowed creating objects of Abstract types (with unimplemented Abstract methods)
- WString conversions from UTF32 to UTF16 produced incorrect high surrogate values (affected conversion from UTF32 to Windows WString, and from Linux WString to UTF16)
- Conversion from UTF32 to Windows WString behaved differently from other UTF32 to UTF16 conversions in FB with regards to truncating surrogate pairs when the destination buffer is full
- #839: Wstring constants could be allocated with the wrong size when cross-compiling, leading to compiler errors and/or incorrect code generation
- WCHR would produce garbage if evaluated with constant values above &h3ffff (any value up to &hffffffffU is allowed)
- WCHR would give the wrong result if given large number of arguments which were large constants
- #846: Fix compiler crash on global variable initializer with type<T>(...) expression where T isn't a UDT
- #847: Windows API binding: Fixed winnt.bi SECURITY_*_AUTHORITY initializers
- #851: '#LINE line filename' only changed the source filename in error messages, not in debug info
- #857: PAINT used in a VIEWport and without delimitation border induces segmentation violation when ending code
- #832: Fix bug allowing QB style suffixes on all keywords, regardless of -lang
- #841: The unary negation operator gave different result signedness when used on constant instead of non-constant expression. Now the result is always signed.
- Incorrect C++ mangling for BYREF parameters using built-in types
- #844: Fix bug in -gen gcc due to duplicated type (struct) names in the main module and global namespace
- #875: Fix bug where boolean variable to single/double conversion gives wrong sign on -gen gas -fpu x87 & sse
- #872: Fix broken boolean bitfield runtime assignments from unsigned values 
- #876: ThreadCall does not support subroutine with [U]Long type parameter

- #878: Fix fbc-64bit hangs on 'Case True' + 'Case False' inside 'Select Case As const'
- Fix SELECT CASE AS CONST to allow both signed & unsigned case range values
- #822, #814, #842: Compiler crash when initializing static/shared reference (DIM SHARED/STATIC BYREF) with non-constant initializer (e.g. another reference, or dynamic array element)
- ASM backend: Fix bad code generated for comparisons such as IF @globalvar = 0 THEN
- #884: FORMATing dates can deadlock under Unix
- #890: Fix Bad @N stdcall suffix for non-trivial byval type parameters with -gen gcc
- #642, #886: CASTs involving CONST qualifiers solved out too early allowing invalid statements to be compiled
- #801: *@(expr) solved to (expr) did not cleanly remove null ptr checks allowing invalid datatype assignment with -exx.  *PTRCHK(@expr) solves to (expr).
- #880: Overload binary operators now support covariant arguments, overloaded procedure resolution changed especially with respect to CONST and non-CONST parameters
- Fix for debugging lines in include files but not in procedures.  Filename debugging information added for module level statements in included files.
- #699: fix new[0] causing infinite loop when calling constructor/destructor list
- #883: when mapping 32 & 64 bit functions for PALETTE [GET] USING, check the data type pointed to and choose one of LONG PTR, LONGINT PTR, INTEGER PTR
- #866: fbc was throwing lexer errors in comments stating with $.  Comments are lexed for directives; allow suffixes in comments
- #858: C backend: fix internal structure size mismatch due to wrong padding when nesting packed structures
- C backend: fix array descriptor mangling to avoid naming conflicts where array data types differ only by const
- #823: Function overload resolution for [const] array() and passing non-const array argument to const array parameter
- Github #113: When a WINDOW was active, the top/right edges (bottom/right for WINDOW SCREEN) were transformed out of the viewport.


Version 1.05.0

[changed]

[added]

[fixed]
- 0.90.0 regression: Self-op optimizations stopped handling some cases and should now work again, for example: optimizing A=A+1 => A+=1 where A is a Long, should give nice ASM code with -gen gas again
- When Dim'ing an Extern variable, the Byref attribute was not checked - neither required nor disallowed - now the Dim must match the Extern with regards to Byref too.
- Type<Foo>(...) expressions couldn't be used at the begin of a statement (because the Type keyword was treated as begin of a Type declaration)
- FileAttr() was still broken for 64bit - the result value was truncated to 32bit
- 1.04.0 regression: Under -gen gcc -asm att, support for gcc-style inline asm was broken
- ld was warning about unsupported linker options on OS X
- BYREF fixed-length strings (e.g. BYREF myParameter AS ZSTRING * 10) now trigger a compiler error since they are unsupported
- #print typeof() output now differentiates between ZSTRING and ZSTRING * N (ZSTRING without size is produced by dereferencing a ZSTRING PTR, or BYREF AS ZSTRING)
- Context-specific keywords, e.g. graphics PUT modes, must now be given as keywords (e.g. PSET), string literals (e.g. "PSET") are no longer accepted.
- Wstring-to-Zstring conversions didn't use the system's Unicode <-> codepage conversion function, and only converted ASCII characters. Now it will try to convert the Unicode chars to codepage chars.
- Compiler crash during error recovery when there was an error when parsing the argument expression for a BYREF AS ANY parameter
- 1.04.0 regression: Get# for WStrings was incorrectly changed to convert the loaded bytes to wstring characters, like Input# would do. Now it's changed back to just loading the raw bytes into the wstring, which is also how Get# works for other datatypes.
- 1.04.0 regression: Due to the Get# wstring breakage, the compiler failed to read source files encoded in UTF16LE with BOM on Windows, and UTF32LE with BOM on Linux.
- Eof() could incorrectly return TRUE too early on Windows, when reading a big text file with LF line endings, OPENed FOR INPUT (text mode)
- Line's styled/pattern drawing support was broken on non-x86 systems


Version 1.04.0

[changed]
- FileAttr() now returns an Integer instead of a Long, and now supports returning OS handles on 64bit
- #750: The gfxlib is now cleaned-up by END (which also happens automatically at the end of the implicit main function), instead of the FB runtime's global destructor. This should fix the "hang on exit on Windows 10" issues. The reason is that the gfxlib clean-up needs to wait for the background thread to exit, which cannot safely be done in a global destructor on Windows, due to the loader lock. This means it is definitely not safe anymore to use FB graphics commands during global variable destructors or module-level destructors.
- Windows API binding: The BOOLEAN typedef has been renamed to WINBOOLEAN due to the addition of built-in Boolean type to FB. You can #undef Boolean before #including windows.bi to get the Windows API BOOLEAN typedef again.
- Many bindings now declare CTRUE (1) instead of TRUE (1), to avoid conflicting with the new built-in True (-1) keyword. You can #undef True before #including them to get their old TRUE (1) again.
- On 64bit, but not -lang qb, integer number literals > 32bit now default to being Integers instead of LongInts, since 64bit Integers are the default type on 64bit. This only makes a difference for overload resolution and typeof(). No changes on 32bit or -lang qb.
- #738: Operator overloading: The overload resolution is now a bit more permissive with regards to CONSTness; for example non-const UDT objects can be passed to Byref As Const UDT parameters, regardless of the other argument/parameter (if it's a binary operator). Previously this was disallowed (though only sometimes, due to a separate issue).
- #756: Val() no longer recognizes 0x or 0X prefixes for hexadecimal values. &h or &H should be used instead. Previously it was only "supported" accidentally, and could produce wrong values (all d's turned into e's in the string before the conversion).

[added]
- BOOLEAN data type (compatible to GCC C++). Logic operations involving boolean operands also return a boolean.
- TRUE/FALSE built-in constants (programs may still declare them manually, but a warning will be shown)
- CBOOL()
- Boolean support for PRINT, INPUT, DATA, WRITE etc. Booleans are represented as "true"/"false" strings (case-insensitive).
- DIM|VAR BYREF id AS datatype, for creating local references to other objects, similar to BYREF parameters
- exepath() now works on FreeBSD, NetBSD, Darwin and Solaris
- The FB gfxlib can now be built on OS X using XQuartz by passing ENABLE_XQUARTZ=1 to make

[fixed]
- False-positive "ambigious sizeof" warnings if the identifier could refer only to a type or procedure (in that case it should already be fairly clear that the type will be chosen, not the procedure, because sizeof() can't be applied to procedures at all), or if an expression such as "array(0)" is given to sizeof() (i.e. something that starts with an identifier but is followed by further tokens that clarify that it's not refering to a type)
- Adjusted "ambigious sizeof" warning message for the case when it could refer to a forward reference or a variable
- 1.03.0 regression: Compiler crash during error recovery in case a CONST declaration was a duplicate definition
- 1.02.0 regression: zlib.bi couldn't be #included behind crt.bi due to the declarations for SEEK_SET & co
- Typedefs allowed the data type or forward reference identifier to be omitted (e.g. "type T as")
- Typedefs allowed forward references named after keywords, even though no such type alias or UDT can be declared (only quirk keywords are allowed as type names, not "core" keywords though)
- #747: SPC(n) only allowed skipping into the next line, and truncated bigger values of n. Now it can skip multiple lines if n is big enough.
- IUP binding: added various missing #inclibs
- #782: C backend: inline ASM keywords were turned into references to previously declared FB variables/procedures/labels, if those were named after ASM keywords. Inline ASM keywords will now be left untouched (using the same heuristic, a list of ASM keywords, as used by the ASM backend).
- __FB_ASM__ wasn't #defined for x86_64 even though the -asm option can be used on x86_64 too
- C backend: UDTs using Field=N were emitted incorrectly (causing gcc errors), if they contained a field of type of another UDT that didn't use Field=N.
- False-positive "ambigious sizeof" warnings if the identifier could refer to a type or variable of that type (in this case the size is obviously the same, and it doesn't matter which one is used)
- C backend: Procedure pointers having a circular dependency on themselves could result in duplicate typedefs being emitted, causing gcc errors with older gcc versions.
- rtlib & gfxlib compilation was broken on NetBSD, Darwin and Solaris (header & include-path issues)
- On Darwin, linking with rtlib failed due to __fb_errmsg being discarded
- Correctly implemented fb_hGetExeName for FreeBSD, NetBSD, Darwin and Solaris (needed by gfxlib2)
- The FB makefile can now detect the OS when building on Solaris
- fbc will now pass the proper parameters to "as" on OS X
- 1.02.0 regression: NULL was declared with pointer type in updated bindings (Windows API, SDL, etc.), and is now just an integer constant again, so it can be passed to things like WPARAM/LPARAM without triggering a compiler warning.
- Open Com on Windows didn't invoke GetCommState() properly, meaning it could "randomly" fail. Also, the port was not always opened for exclusive access, even though MSDN says that is the only possibility.
- 1.03.0 regression: OpenAL binding: The ALboolean and ALCboolean typedefs were incorrectly expanded and translated as zstring in some places
- format(now(), "ttttt") now works as expected under unix-like systems
- -profile now works on win64; the compiler generated calls to "mcount" which doesn't exist on win64; it's named "_mcount" instead. (with MinGW-w64's libgmon at least)
- 1.02.0 regression: CHAR/WCHAR typedefs (and others) in the Windows API bindings were translated as zstring/wstring; they're now translated as byte/wchar_t again (and accordingly in some cases where fields/parameters use them as type and clearly don't want a zero-terminated string), to allow them to refer to a single char again.
- 1.01.0 regression: CGUI binding: InitCgui*() macros were all broken, not just InitCgui() (that was fixed before)
- GdiPlus binding: Fixed GdipMeasureCharacterRanges() declaration (wrong parameter type)
- RETURN in BYREF-result functions could erronously try to construct a result object, if the result UDT had constructor overloads taking a pointer
- LLVM backend: Accesses to fixed-length strings now use the proper types
- LLVM backend: Structs using FIELD=1 are now emitted as packed structs
- Many bindings and especially the Windows API binding now use more proper Const/Type/Extern/Sub/Function declarations instead of #defines, allowing many identifiers (such as "LoadImage" which is also a Windows API function) to be used for custom functions in namespaces, even if the file #includes windows.bi or others.
- 1.02.0 regression: Windows API binding: COM interfaces in win/shlobj.bi were missing vtable entries
- #761: crt/string.bi and win/shlwapi.bi can now be used together - they use #undefs to override each-other (e.g. strcpy() vs StrCpy()), whichever is #included last wins.
- Windows API binding: The NM_* constants from win/commctrl.bi are now adjusted to work on 64bit.
- X11 binding: X11's boolean typedef was errornously translated as string type in some places - it is now preserved, named "XBoolean", and translated as byte as intended.
- GTK+ 2 binding: GtkCurve structure was translated incorrectly (i.e. wrong sizeof())
- 1.02.0 regression: Windows API binding: The LPRGLPVOID typedef and related ones were omitted from win/dplay.bi due to a translation bug
- Windows API binding: win/GdiPlus.bi now uses the Gdiplus namespace and #inclib on 64bit too.
- The @N stdcall suffix was calculated incorrectly (i.e. it was incompatible with gcc and MSVC) for procedures with Byval non-trivial UDT or Byval String parameters.
- Static member variables using the parent UDT as their data type could be allocated incorrectly (not enough memory reserved, possible even zero memory), if they were declared above some or all fields (related to bug #649)
- C backend: References to procedures and labels are now emitted as-is, instead of using gcc's inline asm place-holders with memory reference constraints (the latter only makes sense for variables, not functions/labels)
- C backend: Inline ASM using labels (i.e. jumps) should now work, using gcc's "asm goto()" syntax
- C backend: The register clobber lists produced for inline ASM are now adjusted to the target - now x86_64 and ARM is supported (though ARM/AArch64 support is probably incomplete), no longer x86 only.
- GET# didn't work with wstrings
- Integer-only operations like AND, OR, \ and MOD converted non-integer operands to Integer, even if the other was a LongInt or UInteger. Now the conversion will use an integer type matching the integer operand (if any), to avoid truncating floating point values, and give more expected results.
- ASM backend: Cross-compiling could give different results than native compilation with regards to the choice of whether to place string literals into .data or const (e.g. .rodata) sections
- Compiling a Select Case As Const block containing a Case with a huge range of values such as <case 0 to 4294967295u> won't cause the compiler to "hang" anymore
- Select Case As Const: <CASE a TO b> now triggers a compile-time error if a > b, instead of silently doing nothing
- #784: C backend: String literals in inline ASM (containing double quotes, backslashes, etc.) were emitted into the .c code without escaping
- #777: -lang qb: Suffixed identifiers on the left-hand side of assignments were resolved by prefering global variables instead of local ones. Now local ones take priority, as in other places (e.g. expressions) and as in QB.
- #783: C backend: Run-time float-to-uint64 conversions truncated the value to int64
- #745 part 1: PRINT comma-padding could wrap into the next line too early (if the padding would move the caret beyond column width-FB_TAB_WIDTH). This happened in both console and graphics modes.
- #745 part 2: FB runtime cached the console/graphics window width but didn't update it when it got resized, this should now be fixed at least for the graphics window and Linux console window.
- #743: 1.00.0 regression: len() used on UDT with overloaded cast() operators returned the result type and value of one of these cast operators, instead of the sizeof()
- #738: Operator overloading: The overload resolution gave different results for b+a compared to a+b, if one argument/parameter differed only in CONSTness, and the other didn't.
- #746: -lang qb's Open "Pipe:<shell command>" wasn't working. Only Open "Pipe:" was accepted (but that's useless); anything else was treated as normal Open file command.
- #414: ASM backend: Bad code generated for comparisons such as IF @globalvar = @stackvar THEN ...
- C backend: Extern Import variables were not emitted and accessed correctly


Version 1.03.0

[changed]
- -print now only prints the information, and then stops the compiler
- non-standalone builds: -target <gcctarget> no longer searches libs in lib/freebasic/<gcctarget>, but rather in the normal lib/freebasic/<fbtarget> directory. I.e. the directory layout for native or cross compiling is the same, making packaging and distribution easier.

[added]
- IUP binding updated to 3.13
- #742: fbc can now use lib64/freebasic/... instead of lib/freebasic/ if built with ENABLE_LIB64=1
- -print fblibdir option
- All the recently updated bindings now have copyright/license information
- New libbzip2 binding (64bit-capable)
- New libcaca binding (64bit-capable), libcaca-0.99.beta19
- New BASS 2.4 & BASSMOD 2.0 bindings (64bit-capable)
- New OpenAL (openal-soft-1.16.0) and freealut (1.1.0) bindings (64bit-capable)
- New ASpell 0.60.6.1 binding (64bit-capable)
- New libbfd binding (64bit-capable), supporting all binutils versions from 2.16 to 2.25
- New CanvasDraw 5.8.1 binding (64bit-capable)
- Updated CGUI binding to 2.0.4 (from CGUI project's CVS)
- Redundant constant declarations (CONST A = 1 : CONST A = 1) are now allowed, just like redundant #defines
- logic operation optimization: x <> 0 => x if x is a comparison operation already, and <comparison> = 0 => <inverted-comparison>, and NOT <comparison> => <inverted-comparison>
- ASM backend: slightly better code generation: Integer operand register will be re-used as Long result registers now (and vice-versa), which is ok since this is 32bit-only
- len/sizeof/typeof will now warn if the given identifier is ambigious (i.e. if it could refer to both a type or a procedure/variable symbol), because currently the type will be preferred, which is typically unexpected, at least for len() on strings.
- crt/longdouble.bi: ARM support
- LLVM backend: global variable initializers
- LLVM backend: fixed-size array variables/fields

[fixed]
- Windows API binding: win/ntddndis.bi and win/olectlid.bi headers were missing their content (and thus, the dependencies of ntddndis were missing too)
- LLVM backend: local vars were emitted twice
- LLVM backend: the signature emitted for calls will now use the same param dtypes as in the declaration, as required by LLVM
- LLVM backend: self-BOPs, and the self negation UOP, weren't working
- LLVM backend: field accesses, pointer derefs, global var accesses, with or without offsets, were mostly broken
- LLVM backend: procedure pointers weren't implemented properly
- 1.00.0 regression: compiler crash on assignments with a dereferenced constant on the left side
- 1.00.0 regression: C backend: bad code for pointer array parameter accesses (resulting in gcc error reports)
- Better error recovery after byref function result assignment type mismatch errors
- 1.01.0/1.02.0 regression: Various bindings: some macros using sizeof() were badly translated (doing sizeof((T)), which doesn't compile, instead of sizeof(T))
- Various bindings: macros whose body is a scope block with just one statement are now translated as single-line statements, so that they can be used with single-line IF blocks
- 1.01.0 regression: CGUI binding: InitCgui() macro was broken
- 1.01.0 regression: GLib binding: G_N_ELEMENTS() macro was broken
- Windows API binding: added #inclib "msimg32" to wingdi.bi, for using functions like GradientFill()
- C backend: Bitfields in nested anonymous Types/Unions should no longer cause __fb_struct_size errors - fbc now uses the same work-around for them as for Types with bitfields at the toplevel, i.e. such Types are emitted as byte arrays, because fbc's/gcc's bitfield layout rules differ.
- 1.02.0 regression: Windows API binding: The select() function from winsock headers is now renamed to select_() again, as before
- 1.02.0 regression: Windows API binding: opensocket/selectsocket aliases for the socket_/select_ functions were missing
- 1.02.0 regression: Windows API binding: can be used with MinGW.org again, for the most part, although some individual functions still won't work as they use MinGW-w64-specific helper functions
- Various bindings: Some trivial "inline" functions are now turned into macros; fixed some cases of missing information about renamed symbols (e.g. in SDL2 binding)
- Some built-in functions with wstring parameters (e.g. Val(), Left(), Right()) accepted integers and pointers in place of the wstring (e.g. Val(0)). This triggers an error now.
- #772: Types with the same name but in different namespaces compared as equal in #if typeof(...) = typeof(...) checks and #print typeof(...) output, because the namespace prefix was not included in textual typeof()'s result string.
- For dynamic array parameters with specified number of dimensions (e.g. <(any) as integer> instead of <() as integer>), the number of dimensions in accesses and REDIMs is now checked at compile-time, like dynamic array variables
- 1.00.0 regression: Arrays declared with unknown dimensions ("()") could no longer be accessed with inconsistent dimension counts. This is now allowed again. If precise dimension count checking is wanted, the array should be declared using the "myArray(any, any, ...)" syntax.
- 1.02.0 regression: GL/glext.bi on Windows no longer automatically #included GL/gl.bi


Version 1.02.1

[changed]

[added]
- Package name + version to all the new/updated bindings
- Windows API binding: strsafe.bi and windowsx.bi; COBJMACROS declarations (COM helper macros)
- Windows API binding updated to mingw-w64 4.0.1
- 1.01.0 regression: Allegro 4 binding didn't have #inclibs for Win32 static linking or Linux X11 libs

[fixed]
- 1.02.0 regression: win/winuser.bi: Renamed INPUT typedef to INPUT_ to avoid conflicts with the quirk keyword (due to bug #730)
- 1.02.0 regression: OpenGL binding: glGetString() and some others use ZString Ptr instead of GLubyte Ptr again
- 1.02.0 regression: Windows API binding: REFIID and some other REF* types were missing; wsprintf/wvsprintf declarations were missing; ole2.bi couldn't be included directly/alone anymore.
- bindings: Various previously untranslated (or wrongly translated) #defines in SDL2, X11, crt/pthread, Windows API
- Windows API binding: DirectX headers missed some declarations and some didn't compile, win/commdlg.bi couldn't be #included behind windows.bi without WIN_INCLUDEALL because of missing #includes; re-added the undocumented ENUMWINDOWSPROC type; shlwapi.bi #includes shlobj.bi again (for backwards compatibility), some #defines were missing (e.g. lstrcpy/lstrcat).
- crt/string.bi, crt/mem.bi: Added CONSTs to function declarations
- #767: Illegal byref result assignments will now cause a proper error message, not just a warning
- Using the -asm att|intel option for non-x86[_64] targets now triggers an error
- C backend: -masm=... will now only be passed to gcc for x86[_64] targets
- Screen didn't return an error code if it failed
- Bad code generated for temporary variable destruction in static variable initialization: temporary strings or UDTs with destructors could be destroyed before even being initialized
- "BASE.field" accesses in expressions (not at the start of a line) allowed any token behind "BASE" instead of the ".", for example "BASE : field", or even EOL.


Version 1.02.0

[changed]
- Redims with explicit type will now redim existing dynamic array fields, if one of the same name exists, instead of creating a new local array. This makes Redims with explicit type match the behaviour of typeless Redims and Redims for global arrays.
- Relaxed type checking for procedure pointers and virtual method overrides: Procedures with different signatures can now be treated equal if the signatures are compatible. For example: assignments between a function pointer returning an Integer and one returning a Long won't cause a "suspicious pointer assignment" warning on 32bit anymore.
- -asm intel is now the default for all targets/backends (i.e. the C backend no longer defaults to -asm att). This should make switching between backends less trouble-some, especially with regards to inline ASM.
- The temporary .asm/.c files generated by fbc no longer contain time/date strings. This avoids unnecessary noise (the time/date is essentially always different) when comparing .asm/.c files (e.g. to detect changes in fbc's code generation).

[added]
- __FB_ASM__ intrinsic #define on x86, defined to "intel" or "att" (corresponding to the -asm command line option -- useful for -gen gcc/llvm only)
- fbc -showincludes option (shows #include tree) for debugging of #includes
- Address-of followed by pointer-arithmetic on variables (expressions such as @x+N) will now be turned into offsetted variable accesses, resulting in better generated code
- The results of type-casted function calls can now be ignored, even if it's a non-trivial cast
- Covariant parameters and function results (feature request #289)
- Type aliases for forward-reference type aliases (e.g. "type A as A_ : type B as A" -- previously it was only allowed to alias the forward reference directly: "type A as A_ : type B as A_")
- #761: crt/mem.bi for mem*() functions, separated from crt/string.bi, to allow them to be used together with windows.bi without running into conflicts between crt/string.bi and win/shlwapi.bi
- crt/iconv.bi for using glibc's iconv on GNU/Linux
- crt/regex.bi for using glibc's regex support on GNU/Linux
- crt/pthread.bi for using glibc's pthread support on GNU/Linux
- allegro5 binding: Win32-specific #inclibs supporting the lib naming convention used by Allegro5's Win32 builds
- Bindings (new/updated, including 64bit support):
	FastCGI 2.4.1-SNAP-0311112127

- The FB makefile now supports "make bootstrap-dist" and "make bootstrap" commands. The former allows packaging the FB sources together with precompiled fbc sources, and the latter allows building FB using those precompiled fbc sources, which is useful on systems that don't have a working fbc yet.

[fixed]
- Potential bad code generation for dynamic array field copying
- C backend: Naked functions could end up in the .data section instead of .text
- Returning a dereferenced constant (such as <cptr(UDT ptr, 0)->field>) caused a compiler crash
- 1.00.0 regression: Bad code generation for dynamic array descriptor initialization (and potentially other cases)
- 1.00.0 regression: . member access was allowed on [] pointer indexing expressions even if the type was not an UDT, but a UDT ptr
- Some unsafe pointer assignments between ANY PTRs and non-ANY PTRs with different PTR indirection levels didn't trigger a "suspicious pointer assignment" warning (e.g. ANY PTR PTR = BYTE PTR)
- On 64bit, all number literals with '&' suffix (LONG type) triggered a "too big" warning, even if their value was not really too big.
- #765: insufficient precision on FLT_MAX / DBL_MAX constants in crt/limits.bi
- gfxlib could crash on exit, if Screen[Res] was used in a global/module constructor
- #768: View [Screen] did not clip the given viewport coordinates to the screen properly, if x1/y1 were negative
- 0.90.0 regression: Potential compiler crash with -fpu sse -fpmode fast if the program used sin/cos and contained certain global float constants (such as pi/2)
- 1.00.0 regression: Potential dead-lock in thread-safe runtime library when using file or console I/O functions from multiple threads
- binding: allegro5: Fixed compilation on win32/win64
- Compiler directory layout: The non-standalone (Linux-style) DOS build now uses include/freebas/ and lib/freebas/ if running on DOS, instead of when compiling for DOS. This allows cross-compiling from Linux (or others) to DOS to work again: If on Linux, fbc -target dos will now use the normal include/freebasic/ and lib/freebasic/ directories of the Linux compiler, instead of requiring the 8.3-compatible directories.
- Extern variables were allowed to have mismatching fixed-length string lengths in declaration and definition
- 0.90.0 regression: In -lang qb, using __offsetof() caused a compiler error
- -lang qb's __offsetof() won't truncate the offset to 16 bit anymore
- Unix rtlib: division-by-zero crash on console I/O commands such as Input, if the terminal size couldn't be queried
- Unix rtlib: memory leak in X11 keyboard input handling initialization
- rtlib/gfxlib2: memory leaks of internal thread-specific data (gfxlib's TLS data when using the thread-safe (mt) FB runtime, and all TLS data of the main thread when using the normal (non-mt) FB runtime)
- rtlib: When using Open Scrn, there could be a dangling pointer bug in the internal screen file handle


Version 1.01.0

[changed]
- On Linux/*BSD, the FB runtime will now delay using VT100 terminal escape sequences to query terminal window size and cursor position until the first use of a console I/O command (previously it was immediately done at startup, always, even if the FB program didn't use any of FB's console I/O commands)
- WITH ... END WITH blocks now have an implicit scope, like SELECT, DO ... LOOP, etc. Variables declared inside will no longer be visible outside.
- Identifier length limit increased from 64 to 128 (due to Windows API headers which contain at least one identifier with 68 chars)

[added]
- On Linux/*BSD, the FB runtime will now respect the __fb_enable_vt100_escapes global variable (also see examples/console/disable-vt100-escapes.bas). FB programs can set it to 0 (FALSE) in order to manually disable the use of hard-coded VT100-specific escape sequences by FB's console I/O commands. This can help getting FB programs to run on older terminals which don't accept these escape sequences. However, it may also cause FB's console I/O commands and functions to behave differently. For example, if the use of the escape sequence for querying cursor position is disabled, then the FB runtime will assume that the cursor starts out at position 1,1 even if that is not actually true.
- WITH compounds now also accept type<UDT>(...) and UDT(...) expressions
- Constant 0 integers can now be assigned to pointers no matter what integer type it is. Previously it didn't work with [U]LongInts on 32bit and [U]Longs on 64bit.
- Constant 0 pointers can now be assigned to any integer type. Previously this was only allowed with integer types matching the pointer size (32bit or 64bit).
- #757: It's now possible to do UDT().field instead of (UDT()).field (field accesses on anonymous UDTs with constructors)
- On 64bit, bitfields can now use the [U]LongInt type
- Bindings (new/updated, including 64bit support):
	Allegro 4.4.2 (allegro.bi)
	algif 1.3 (allegro/algif.bi)
	alpng 1.3 (allegro/alpng.bi)
	Allegro 5.0.10 (allegro5/allegro.bi, plus the addons such as allegro5/allegro_font.bi)
	CGUI 2.0.3
	CUnit 2.1-3
	fmod.bi for the old FMOD 3.75

	crt/sys/types.bi now provides off_t on Windows, like MinGW.org and MinGW-w64

[fixed]
- 1.00.0 regression: DRAW x/y pen position was reset during X<address> subcommands, instead of being preserved and passed to/from the subcommands
- 1.00.0 regression: C backend: Bad code generated when taking the address of __FB_ARGV__, resulting in a gcc error.
- Linux/*BSD: FB programs run in the background (CTRL+Z + bg) could hang on exit due to the FB runtime triggering a SIGTTOU
- -gen gcc: Single-precision constants were being emitted with precision less than 24 bits
- 1.00.0 regression: When compiling on DOS, \ backslashes were passed to the linker as \\ causing it to fail opening the passed files
- An fixed-size array variable declared behind a dynamic array variable in the same statement (for example <DIM AS INTEGER a(), b(0 to 1)>) was accidentally made dynamic too
- 1.00.0 regression: "REDIM Foo.array()" created a new local array called "array" (ignoring the "Foo." namespace prefix) if Foo.array was an existing variable and not a declared-but-not-yet-defined EXTERN (or static member variable). This will trigger an error again now. In FB 0.90.1 the error was "duplicate definition". Now it will be "declaration outside the original namespace or class", to match the behaviour for non-array variables.
- Type-less (and dimension-less) REDIM was allowed to define EXTERN dynamic arrays, even though DIM is not allowed to be type-less for defining EXTERN variables
- 1.00.0 regression: Compiler crash after showing an error when defining a non-array EXTERN using an array declaration
- 1.00.0 regression: lhsint &= rhsint self-assignments, where the lhsint expression included a function call, didn't result in a "type mismatch" error anymore, even though the string result of the & concatenation operation couldn't be assigned back to the lhsint.
- Self-assignments will now be parsed correctly when the lhs is a call to a function with byref result and one argument, for example: f(0) += 1
- Partial fix for #740 (unsafe FB runtime signal handling code): Fixed a potential dead lock and unnecessary terminal size query in the Unix rtlib.
- 0.90.0 + 1.00.0 regressions: SELECT CASE [AS CONST], FOR, and WITH were broken if the given expression(s) contained temporary variables, for example a function call with dynamic string parameters where the passed arguments were string literals. The temporary strings or UDT objects were destructed too early, before even being initialized, causing undefined behaviour. Temporary dynamic strings were affected by the problem since FB 1.00.0. Temporary UDT objects were affected by the problem since FB 0.90.0.
- #522 (part 1): WITH destroyed temp vars before entering the block. Now they will be kept alive until END WITH (or any EXIT/RETURN/GOTO out of the WITH block).
- #522 (part 2): WITH produced bad code on Win32 when used on function call returning a small UDT (i.e. where the UDT is returned in registers)
- Win32 gfxlib2 did not process thread messages, causing problems with response to system hotkeys and potentially more
- Hiword() on 64bit didn't filter out the upper dword when given a 64bit value
- The compiler incorrectly added leading underscores to ASM symbols on Win64 and 64bit Cygwin. Leading underscores are only used by Win32, not by Win64 though.
- #744: False-positive "recursive define" error messages in some situations with multiple/consecutive/nested (but non-recursive) macro expansions in the same line
- #478: DRAW "Mx,y" was offsetting subpixel precision by 0.5, leading to rounding errors e.g. in "Pp,b"
- DRAW now draws U/E/R/F/D/G/L/H using line-drawing routines rather than pixel-by-pixel, resulting in steadier lines and much better speed
- DRAW was not unsetting the B/N qualifiers after 0-length directional commands, e.g. "R0", resulting in them being applied to the following command, e.g. DRAW "B U0D0L0R0 R10" would not draw "R10"
- Bad code was generated when initializing integer variables with a wstring-indexing expressions
- #723: LINE clipping now doesn't affect which (unclipped) pixels are plotted, eliminating rounding differences and correctly preserving the position of the style bits
- BLOAD now gives an error if it encounters a BMP file with an unknown header size
- BLOAD was misreading bitfields in BMP files with undocumented BITMAPV3HEADER format (56-byte headers)
- PRINT now disallows commas/newlines after SPC/TAB, instead of silently ignoring them
- 0.90.0 regression: Compiler crash during error recovery for expressions like 'type<UDT>().field' where initializer values are missing
- When passing a constant zero of some integer to an overloaded procedure, overloads with integer parameters will now be preferred over overloads with pointers (literal 0 can still be passed to pointer parameters in this case though, by casting it to the pointer type)
- Literal zeroes with [U]Byte or [U]Short type (or the 16bit Integer in -lang qb) can now be passed to pointer parameters of overloaded procedures (now it's possible to call Bsave() with 0 source buffer in -lang qb again -- it also was affected by this bug since FB 0.90)
- #760: RETURN and FUNCTION= couldn't be used together in byref functions returning an UDT with constructor. This check is now only applied to functions returning byval.
- #755: If no result is set in byref functions, the compiler will now show an error instead of a warning (because a byref function defaults to returning a null reference, most likely causing a crash at runtime)
- Better error message for function result assignments outside of the function (#754), and for illegal use of Exit Sub|Function|...
- #748: Static member variables in UDTs inside procedures or scope blocks were allowed without error message (but didn't and cannot fully work in this situation, like methods). The compiler will now show an error in this case.


Version 1.00.0 (former 0.91.0):

[changed]
- Platform naming conventions have changed for Linux/BSD due to 64bit/ARM support. dos/win32/xbox stay the same, win64 is added, and we use the <os>-<cpufamily> format for other systems (Linux/*BSD/Cygwin): linux-x86, linux-x86_64, linux-arm, etc. This affects the compiler's -target option, installation directory layout, release packages, compiler -v output, etc. but not any FB code.
- The normal (non-standalone) compiler now uses target-specific sub-directories in lib/freebasic/ again, for example lib/freebasic/linux-x86/, to allow libs for other targets to be installed into the same directory, for example lib/freebasic/linux-x86_64/, instead of having to use a separate directory like lib/freebasic-linux-x86_64/. Same goes for the FB makefile: the *.o files go into target-specific subdirs in src/{compiler,rtlib,gfxlib2}/obj/, to avoid trashing the source dirs with tons of separate obj-<target>/ subdirs.
- More predictable overload resolution for primitive types, preferring: the same dataclass >> a type that's at least as large >> the closest in size >> the same signedness >> the same kind >> the [U]INTEGER type
- Bin/Oct/Hex(x, digits) functions now prepend zeroes, even if it's more than the data type size, if needed to fill the result string up to the requested amount of digits
- Number literal suffixes are now followed more strictly. For example, a number with L suffix will now always be a 32bit LONG (previously it could be 32bit or 64bit, signed or unsigned, depending on the value), and the % integer suffix will always produce the FB dialect mode's default INTEGER type (INTEGER, or SHORT in -lang qb), but never a [U]LONGINT anymore.
- CONST isn't allowed/needed on constructors/destructors anymore, the non-CONST versions now work even with CONST objects. (A CONST constructor couldn't initialize the object, so it's not useful. And after a destructor runs, the object is "dead", so it doesn't matter whether the destructor modified it or not.)
- DOS rtlib no longer uses setlocale(), as FB-dos doesn't support Unicode anyways, and thus the setlocale() reference here only served to unnecessarily increase .exe size.
- #if expressions allow quirk function names to be used as literals again, so for example <#IF TYPEOF(x) = STRING> works again, instead of complaining about missing arguments in a call to the String() function.
- For dynamic arrays where the dimension count is known at the point of the declaration, fbc will now allocate array descriptors with room for only the amount of required dimensions. Descriptors with room for all of FB_MAXARRAYDIMS will only be used for dynamic arrays declared with '()' (unknown dimension count) now.
- The C++-compatible name mangling for procedures with BYDESC parameters has been adjusted to match the implementation of BYDESC parameters, and to support the new '(any[, ...])' syntax.
- #699: The default global New/New[]/Delete/Delete[] operators now simply use allocate()/deallocate() internally, instead of the functions from GCC's libsupc++. This avoids platform-dependant behaviour of the GCC functions (exception throwing, aborting) in case of allocation failure (instead, NULL will be returned as with allocate()).
- FB no longer uses libsupc++ (from GCC's libstdc++) by default
- The implicitly generated copy constructors and LET overloads will now have "BYREF AS CONST MyUdt" parameters (previously they didn't use CONST), to allow copying from CONST objects to work at least for the built-in data types or with nested UDTs. For backwards compatibility, if there is a user-defined "UDT.let(byref as UDT)" LET overload, FB will still add the non-const "UDT.constructor(byref as UDT)" copy-constructor. It's still the programmer's responsibility to write proper "byref as const UDT" versions of the copy-constructor or LET overload if the UDT needs deep-copying and CONST instances of the UDT are being used.
- Function pointer types that differ only in function result CONSTness will now be seen as different, as in C++. Function pointer types that differ only in BYVAL parameter CONSTness will now be seen as being the same, as in C++.
- Some internal data structures and fields ($fb_RTTI, $fb_Object, $base, $vptr) have been renamed from $foo to foo$ to prevent gdb/STABS debugging data confusion, because a leading $ has special meaning there.
- user32 is now linked in by default when compiling for Windows (and Cygwin) as it's sometimes needed by MinGW-w64's libmingwex

[added]
- 64bit support (currently x86_64 and aarch64, based on -gen gcc): INTEGER/POINTER = 64bit, LONG = 32bit DWORD. Compiler #define: __FB_64BIT__
- -arch 32|64 options to support easy switching between 32bit and 64bit, by selecting a default arch that supports 32/64 bits respectively.
- ARM support (currently armv6|armv7-a|aarch64) based on -gen gcc. Compiler #define: __FB_ARM__
- To support non-x86 Unix shared libraries, there will now be PIC (position-independent code) versions of the FB libs for such systems: fbrt0pic.o, libfbpic.a, etc. The compiler will automatically use them when making a non-x86 Unix shared library.
- -pic option for generating position-independent code for non-x86 Unix shared libraries (automatically enabled by -dll, but must be given manually when compiling code via -c or -lib, if it will later be linked into a shared library)
- fbc -v now prints out the target system and architecture
- BYVAL AS STRING is now working properly: it now has BYVAL semantics and no longer behaves like BYREF AS ZSTRING. Modifications made by the callee are not visible to the caller, as for other BYVAL parameters. (BYVAL AS STRING is implemented by copying the string argument into a temporary STRING, whose descriptor is then passed BYREF to the procedure)
- New syntax for declaring dynamic arrays with certain amount of dimensions (but no initial bounds): DIM array(ANY) AS INTEGER (1 dimension), DIM array(ANY, ANY) AS INTEGER (2 dimensions), etc. This allows for better compile-time checking of dynamic array parameters, and also allows the compiler to allocate smaller array descriptors which is especially useful for dynamic array fields.
- Dynamic array fields are now supported in UDTs (for example: array(ANY) AS INTEGER). Similar rules as for dynamic string fields apply: Just the array descriptor is included in the UDT, not the actual array data. The UDT will become a class, and is given an implicit constructor and destructor to initialize the array descriptor, or free the data it contains. This code will also automatically be added to user-defined constructors/destructors.
- REDIM now also accepts expressions to access dynamic arrays, instead of just plain identifiers, which is needed to redim dynamic array fields, or dynamic arrays that are static member variables. For example: REDIM (this.array)(0 to 1)
- Improved multiplication/division/modulus to bitwise shift/and optimizations to handle operations with 64bit and unsigned right hand operand better
- Updated header for libzip 0.11.1
- Indexing/member dereferencing operators ([], ->) can now be applied to VARPTR/PROCPTR/STRPTR/SADD() expressions (for example: print strptr(s)[1]), instead of requiring the address expression to be wrapped in parentheses first.
- FLT_MAX and DBL_MAX to crt/limits.bi
- operator [] overloading support, for example: type MyStringClass : declare operator []( index as integer ) byref as integer : ...
- warning message when mixing signed and unsigned operands in comparisons or integer divide/MOD/SHR operations, where the signedness could change the result
- crt/long.bi, which provides the CLONG and CULONG type aliases that always match C's long and unsigned long data types (for use when making FB bindings for C libraries that use C's long data type, because 64bit FB doesn't have a built-in type that matches 64bit C's long on all platforms)
- crt/longdouble.bi, which provides a CLONGDOUBLE type that (at least in size) matches C's long double type, for use by bindings.
- Adjusted CRT headers for 64bit support
- Updated CUnit 2.1-2 headers, with 64bit support
- #macro can now also be used to #define macros without a '()' macro parameter list
- #438: Checking of parameter initializer expressions: When a parameter has a different initializer in the procedure prototype and in the procedure body, a warning will be shown now. Previously, the compiler silently ignored the initializer from the body and always used the one from the prototype.
- Taking the address of an anonymous object created by constructor call is now allowed by the compiler: @UdtWithCtor( <ctor-params...> )  It already worked for anonymous objects of UDTs without constructor: @type<UdtWithoutCtor>( ... )
- crt/linux/syslog.bi header
- GFX statements now accept UDTs as target/source images, if the UDT has cast() AS ANY PTR (or other PTR types) operator overloads
- jpeglib example now works with both fb and fblite dialects
- Any function result may now be ignored at the call site (simply by not using the function result in any expression or assignment). Previously this was only allowed for functions returning integer types or pointers.
- Thread-safe version of the FB graphics library (libfbgfxmt), used automatically if FB's threading functions are used or fbc's -mt command line option is given, just like the thread-safe version of the FB runtime library (libfbmt).
- NEW/DELETE and NEW[]/DELETE[] can now be used with the dynamic STRING data type
- ThreadDetach() function in fbthread.bi: alternative to ThreadWait() that cleans up the thread handle but does not wait for the thread to finish.
- IsRedirected() function in fbio.bi, that can be used to check whether stdin or stdout is redirected to a file or not
- Dynamic array descriptors will now always be generated with the FBARRAY.data and FBARRAY.ptr pointer fields specialized for the array's original data type, improving the -g debug info
- Len() can now be overloaded as an operator for user-defined types
- Suspicious pointer assignment warnings will now be shown for constant declarations too
- CONST can now be used to declare UDT/string/procedure pointer constants, for example: CONST p AS MyUdt PTR = 0

[fixed]
- dlltool syntax error when building a DLL without any EXPORTs
- ImageDestroy() won't crash anymore if given a NULL pointer
- The compiler didn't check ALIAS names (if given in both DECLARE prototype and procedure body) for equality
- Compiler crash after showing error for "dim shared E as E" where E is an Enum declared inside an Extern block
- Compiler crash on Explicit Enum declared inside Extern block
- #if typeof() and #print typeof() will now take the full procedure pointer type including parameters, calling convention (if non-default), etc. into account, instead of just treating everything as "FUNCTION PTR".
- #669: Compiler crash instead of error message for Static member variables declared inside anonymous UDTs
- #675: SHARED variable initializers referencing a non-SHARED STATIC from the implicit main() scope triggered an internal compiler error (dangling pointer), instead of resulting in an error message.
- Various implicitly generated variables (such as FOR/WITH/SELECT CASE temp vars) won't appear in -g stabs output anymore
- #597: Illegal ASM generated for +,-,*,/ floating point operations when the right hand-side operand was a byte or ubyte variable enclosed in a cast to double or single
- #677: Casts changing only signedness on the rhs of a +,-,*,/ floating point operation could be ignored
- Using #undef (or Option NoKeyWord) on symbols which are already in use somewhere won't cause internal compiler errors anymore: The compiler will now simply forget the symbol's identifier, so it cannot be used from input code anymore, instead of fully deleting the symbol and possibly corrupting the compiler's internal data structures.
- #671: Arguments weren't always converted to the parameters' data type, causing gcc pointer mismatch warnings under -gen gcc
- #670: Functions returning a Byref result weren't allowed to return references to elements from array parameters
- Mid() statement didn't allow some string expressions as destination, such as <Mid( *StrPtr( s ), ... ) = ...>
- The UINT_MAX from crt/limits.bi was an INTEGER instead of UINTEGER
- #defines with invalid or missing identifiers were ignored instead of causing a compiler error
- #686: Statements with lots of identifier/keyword tokens (such as procedure pointer variable declarations with 10 parameters) could cause unexpected compiler behaviour, e.g. compiler errors even though the code was good.
- The compiler allowed integer arguments to be passed to BYREF AS Z/WSTRING parameters, treating them as pointers
- #603: Optional parameters for which no arguments were given could break overload resolution. Now, overload resolution will only search for matching overloads based on the given arguments.
- Overload resolution if no arguments were given will no longer prefer a parameter-less overload over one with only optional parameters. This is now an ambigious call error, as in C++, for consistency with overload resolution with one argument given between two overloads, both with the same first parameter, and one having a second optional parameter.
- #689: Bad code generated for GET #, , array(), , bytesread (bytesread variable not passed on to fb_FileGetArrayIOB(): the last argument was completely missing)
- The compiler allowed fixed-length z/w/string variables to be initialized with integers, leading to bad code generation or runtime crashes. Now only strings should be allowed.
- #691: 0.24 regression: The compiler didn't prevent linking .so's against themselves, causing an ld error
- 0.90.0 regression: When dragging a window on Win32 with the OpenGL gfxlib2 driver, it was resized to minimum size
- #663: For virtual methods, base.method() called the overriding method, instead of the base's own method
- The Is operator (RTTI) treated UDTs with the same identifier but from different namespaces as being equal
- RTTI/Vtables inside namespaces used GCC-incompatible name mangling
- #616: Assignments between pointers and floats are now disallowed, matching the behaviour for assignments between pointers and other incompatible data types
- fbc -g generated wrong stabs definitions for UDTs whose size had to be rounded up (tail padding), preventing gdb from properly showing the content of arrays of such UDTs
- #651: Multiple cases of bad ASM code generation for expressions involving LONGINTs, observable mostly when compiled under -exx due to the additional register spilling due to calls to pointer/bound checking functions (affected -gen gas only)
- inc/win/*.bi headers: PC* and LPC* typedefs were not marked as const ptrs
- -gen gas asm error when the rhs operand to SHL/SHR is a constant value greater than 255
- C backend: Won't generate #line 0 at the top of procedures under -g anymore
- C backend: Will now generate #lines for procedure headers under -g (improved debugging support under -gen gcc)
- #703: Compiler crash after recovering from "ElseIf behind Else" error
- The Win32 gfxlib2 will now use a (more) unique name for the window class it registers to create the graphics window, to prevent issues when using multiple gfxlib2 instances in parallel in the same process.
- Non-standalone fbc builds failed with a "not found" error when having to execute compiler tools repeatedly (i.e. when compiling multiple modules instead of just one), if the tools weren't present in the same directory tree as fbc, such that fbc had to rely on the PATH environment to find them, on systems where exec() won't search the PATH (i.e. DOS/Win32)
- crt/ctype.bi: The isascii() and toascii() CRT function declarations used wrong name mangling, and on Win32 the wrong calling convention too
- crt/bits/pthreadtypes.bi: Various type aliases (including pthread_t) and UDT fields were wrong (used a 64bit integer type instead of a 32bit type like the original C header, assuming a 32bit system)
- crt/win32/process.bi: spawnvpe()'s and _spawnvpe()'s last parameter type was wrong
- #434: win/winbase.bi's RtlFillMemory() declaration was wrong (it was just an alias for memset(), but actually it should be memset() with swapped fill/length parameters)
- crt/stddef.bi: Now uses signed 32bit wchar_t for Linux, to match glibc, instead of unsigned 32bit
- crt/stdint.bi: WCHAR_MIN/WCHAR_MAX/WINT_MIN/WINT_MAX declarations were incomplete
- Debugging help: For dynamic arrays, the compiler will now always name the array descriptor symbol after the original array name
- datetime.bi: DateDiff() was declared to return a 32bit integer while the rtlib actually returns a 64bit integer
- SELECT CASE AS CONST was ignoring the upper 32 bits of 64bit integer expressions in 32bit mode
- ICE (dangling pointer) with type initializer expressions, which is known to at least cause a compiler hang during error recovery
- #705: REDIM in a procedure marked with STATIC did not create a STATIC dynamic array (on heap, preserved to next call), but only a local dynamic array (on stack)
- STATIC declarations couldn't use variables for array bounds, but only compile-time constants
- STATIC declarations ignored OPTION DYNAMIC
- zlib example tried to modify a string literal, which would cause it to crash on Linux or with -gen gcc
- The compiler could sometimes ignore casts in address-of expressions, for example "@cuint( *integerptr )" returned an INTEGER PTR instead of a UINTEGER PTR
- #699: "New Integer[-1]" or similar uses of New[] with negative size, that will wrap around to a massively huge value because the size is treated as unsigned, caused the ASM backend to try to emit GiBs of MOV instructions (one for each 4 bytes...), seemingly causing the compiler to hang.
- #696: Bad code generated for temporary variable destruction (such as temporary strings from String IIf()) used as argument to built-in statements such as Open or Draw String when -e/ex/exx error checking was enabled
- On Linux/*BSD, shell(), exec(), run(), chain(), dylibload(), dylibunload() weren't thread-safe (due to Unix rtlib's console I/O handling)
- C backend: Nested anonymous structures could be emitted incorrectly, potentially causing them to be too small, which could easily result in buffer overflows on stack due to local variables of that struct type being smaller than expected
- filecopy() (for DOS/Linux/*BSD) can now handle large files (> 2 GiB)
- Using -asm att together with the ASM backend (-gen gas) now results in an error, because it only supports -asm intel
- Uninitialized variable accessed in format()
- =Any initializer on fields didn't cause an implicit constructor to be added as for other field initializers
- UByte/UShort versions of Bin/Hex/WBin/WHex( n, digits ) functions were missing
- Miscompilation of runtime library function calls for ImageCreate(), Mki() and ThreadCall, in modules except the first when compiling multiple modules in one invocation of fbc, if -lang qb was given on the fbc command line (not as #lang "qb" in the source).
- C backend: String literal emitting now also escapes characters that would otherwise form trigraphs
- big_int binding: Some function declarations were missing parameters; also added some missing functions
- 0.90.1 regression: PMAP was returning bad values for func values of 0 or 1.
- #701: fbc didn't escape \ as \\ in @files (response files) sometimes used when invoking ld
- Win32 fbc will now avoid hitting Win32 command line length limits when invoking ld with a long command line, by using "ld @file" (response files)
- #713: gfxlib2 crashed when closing and re-opening an X11 OpenGL graphics screen
- ThreadCall on Win32 couldn't be used with procedures declared inside Extern "Windows-MS" blocks
- CIRCLE did sometimes not fully update the screen immediately, causing the last scan line of the circle to remain invisible until the screen was updated some other way
- crt/linux/fnctl.bi: Broken declaration of open_ ALIAS "open"() (0.90.0 regression)
- Using Unicode characters in comments and compiling with -g could lead to junk bytes being emitted into the generated .asm/.c files
- #710: Operator Placement New[] ("new(address) DataType[N]") will no longer store a cookie containing the number of vector elements (N) in front of the allocated buffer, as done by normal New[]. The cookie is an implementation detail that the coder can't be expected to know, especially because it only applies to New[] when used with data type that has a destructor, so the buffer given to Placement New[] will likely be too small. Besides that, the cookie is only useful to Delete[], which however can only be used with New[], but not Placement New[] (no way to be sure that the given buffer even can be Delete[]'d).
- Bad code generated when using type<string>(...) in a string concatenation or as argument to a BYREF AS ANY parameter
- -fpu sse: Bad code generated for negation on Single function result returned through FPU stack
- -fpu sse: Bad code generated when calling sgn() on Single function result returned through FPU stack
- -fpu sse: Bad code generated when calling sqr() on Double function result returned through FPU stack
- -fpu sse and -vec 1|2: Various cases of bad code generation resulting in operand size mismatch errors
- fbc crashed after showing the error message when using -vec 1|2 without -fpu sse
- ASM backend: Sgn(LongInt) returned wrong values
- C backend: Extern "Windows-MS" is now supported, including DLL exports (stdcall procedures without @N suffix)
- #709: format() adds erroneous thousands delimiter, was affecting all number strings that were multiple of 3.
- #715: GFX statements (Get, Put, Line, Circle, ...) are now more strict about their target/source image parameters. Arrays are still accepted as in QB, but besides that, the argument must be some pointer expression now, that is expected to point to an FB.IMAGE buffer of the proper size. Previously non-pointer expressions were accepted but could cause bad code to be generated or could be silently miscompiled.
- #665: DRAW statement now accepts the same target image expressions as the rest of GFX statements (not just simple pointer variables or 'a.b' field accesses anymore)
- #687: DRAW statement now remembers the subpixel position between commands.
- #717: REDIM [PRESERVE] did not clear array elements with destructor but no constructor
- x->*field syntax wasn't working if operator -> was overloaded
- x[a][b] syntax wasn't working if operator [] was overloaded
- x[a].field syntax wasn't working if operator [] was overloaded
- Win32 ScreenInfo() reimplemented to report screen size more accurately (the old version returned incorrect values on Windows 8.1). Also, it will now report the size of the screen assigned to the program, rather than always the primary monitor.
- #assert inside #if 0 blocks caused a syntax error
- PP typeof()'s argument was not being macro-expanded properly (e.g. the x in <#if typeof(x) = ...>)
- Macro expansion right behind a PP typeof() wasn't working (e.g. the foo in <#if typeof(x) foo>)
- Crash (division by zero) when PRINTing onto tiny graphics screens (e.g. screenres 1, 1)
- pdflib.bi was missing #inclib "gdi32"
- Methods with CONST function results are no longer allowed to override virtual methods with non-CONST function results, and vice-versa (the return type must be the exact same, as for function pointers)
- CONST-member methods are no longer allowed to override non-CONST-member virtual methods, and vice-versa
- The compiler no longer crashes (SIGFPE) on constant expressions containing signed integer division overflows, e.g. -2147483648 \ -1, which triggers SIGFPE when calculated on x86. The compiler now inserts 0 (-2147483648 \ -1 = 2147483648 which doesn't fit into a 32bit signed integer, and in theory overflows to 0) and shows a warning. Note: FB programs doing such divisions at run-time (e.g. <dim a as integer = -2147483648, b as integer = -1 : print a \ b>) may still run into SIGFPE crashes; this change just affects the compiler itself, not the generated code.
- When calling a byref function through a function pointer, the result may now be ignored, just like with normal function calls, or when calling normal functions through function pointers.
- STRPTR() on a CONST STRING (DIM s AS CONST STRING) did not preserve CONSTness and allowed modifying the string
- win/objbase.bi: Wrong IsEqualGUID() declaration, producing wrong result value (subsequently, all aliases such as IsEqualIID() were wrong too)
- Fields were allowed to have type suffixes when declared using the "AS DataType a, b, c" syntax instead of "a AS DataType"
- When DIM'ing an EXTERN array, the DIM statement was allowed to have different lbound than the EXTERN
- Compiler crash during error recovery if a dynamic array declaration/REDIM contained '...' ellipsis upper bounds
- EOF() didn't work properly with files bigger than 4 GB
- #643: Typeless REDIM was accidentially being allowed, if the array's identifier matched that of a field visible through the implicit THIS reference, by re-using the field's data type, but still creating a new array. This will now trigger a compiler error just like other typeless REDIMs without a pre-existing array.
- Duplicate EXTERNs for dynamic arrays are now allowed, just like duplicate EXTERNs for normal or fixed-size array variables, which already were allowed before.
- EXTERN variables could be allocated via a static array variable declaration, this will now trigger an error.
- #648: Local (scoped) variable declarations (including REDIM) caused EXTERNs to be allocated, instead of shadowing them
- Local dynamic arrays can now be shadowed in nested scopes without compiler error
- More precise compile-time checks of dynamic array dimension counts
- -lang fblite/qb: EXTERN arrays are no longer allowed to have subcripts if OPTION DYNAMIC was in effect, because EXTERN dynamic arrays cannot have initial subscripts, just like COMMON arrays.
- #720: Some pointer assignments weren't working due to bogus CONSTness checking
- #582: Wrong code generated for bitfield self-BOPs or SWAPs sometimes under -exx or if the bitfield expression contained function calls (side-effects)
- When specifying an .o file name without extension but '.' in its path (for example: -o ../foo), fbc created temporary files by stripping everything from the .o path until that '.' and then appending the new extension, which often resulted in bad/unexpected file names (for example: ..foo.asm).
- Calling getkey() in one thread won't cause other threads' rtlib function calls to block until getkey() returns anymore
- #726: CONSTRUCTOR|DESTRUCTOR (module-level initialization/cleanup) was allowed to be specified on sub prototypes (although, it was ignored), method bodies (silently miscompiled due to the missing THIS argument), and PRIVATE/PROTECTED static member procedures. Now these cases are disallowed.
- #576: Array elements could be passed to array parameters in place of the array itself: <myfunction( myarray(index) )>. However, the array index was simply ignored. The array must be passed without index now: <myfunction( myarray() )>
- #722: Member operators NEW/DELETE/NEW[]/DELETE[] could be declared CONST/VIRTUAL/ABSTRACT despite being implicitly STATIC. This is now disallowed.
- C backend: main() will now be emitted with clang-compatible signature
- C/LLVM backends: Procedures using forward references in their signatures could be emitted with ANY PTRs in place of the forward references, while prototypes/calls could end up using the signature with resolved forward references, causing the generated C/LLVM code to have type conflicts.
- #719: Compiler crash when passing an upcasted class/UDT function result to a Byref parameter
- #698: sizeof() now allows string expressions (note: it returns sizeof(string), not the string length - len() should be used for that)
- #685: SETMOUSE had differing behaviour between platforms when x and y were not both present and within the window
- When RETURN'ing classes without copy-constructor from a function, or passing classes without copy-constructor to a Byval parameter, their Let operator overload was called, even though this is an object initialization, and not an assignment. (the object wasn't even initialized before the Let overload was called)
- Overload resolution didn't allow up-casting arguments when passing to a CONST parameter (e.g. BYREF AS CONST). This also prevented copy constructors with BYREF AS CONST parameter from being called, when the source object had to be up-casted.
- Copy-constructing or assigning an object from a CONST object didn't work with the implicitly generated copy-constructor or LET overload because they only had BYREF AS MyClass parameters which can't accept CONST objects (instead of calling the copy-constructor or LET overload, a shallow copy was done, which for example caused trouble if the UDT contained dynamic strings requiring a deep copy)
- C backend: A gcc warning was triggered when initializing a global variable with an @addressof expression, taking the address of another global.
- #614: When copying (copy-constructing or assigning) objects of classes extending OBJECT, the lhs' vptr could be overwritten incorrectly, causing the object to have a wrong run-time type.
- 0.90.0 regression: -g could produce bad stabs info when #includes were used (after closing an #include block, the wrong directive was used to return to the main file), preventing gdb from determining variable types sometimes
- -g will now produce correct stabs info for dynamic array descriptors
- 0.90.0 regression: Sometimes incorrect C++ mangling of procedures in nested namespaces
- 0.24.0 regression: SWAP called temporary variable destructors too early, even before calling constructors
- Temporary strings used during procedure calls could be freed too early (directly after the call, instead of being kept alive until the end of the statement), potentially leaving references to them (used with-in the same statement) dangling.
- #545: Overload resolution will now properly handle arguments with CONST qualifiers in their data type
- ASM backend -g debug info for dynamic array descriptors: The data type of the DATA & PTR pointer fields was wrong (they were emitted with an extra level of pointer indirection that shouldn't have been there). The DATA pointer field will also now have the array's original data type, while the PTR field is an ANY PTR (since it's the dynamic array's memory block, not necessarily the array data). The dimTB field will now be emitted as the array that it is (instead of as a sequence of manually generated fields).
- Any function pointers were allowed to be assigned to function pointers with varargs, as long as the signature outside the varargs part matched. On x86 this is technically ok for an assignment with types like "sub cdecl( byval as integer ) = sub cdecl( byval as integer, ... )", because the lhs can be called just like the rhs without passing any varargs. But this isn't allowed in C, and isn't necessarily safe on non-x86 platforms. Besides it also allowed BYREF or array (bydesc) parameters in place of the varargs, which breaks even on x86 (e.g. "sub cdecl( byval as integer, byref as integer ) = sub cdecl( byval as integer, ... )")
- Pointer assignments between pointers to different unsolved forward references will now trigger "suspicious" warnings because these forward references may be resolved to different types later. This matches the C++ mangling behaviour which also treats different unsolved forward references as different types.
- Destructors of UDTs with ABSTRACT/VIRTUAL methods will now reset the object's RTTI such that it matches the type whose destructor is running. This prevents virtual calls from a base class destructor into a derived class which has already been destructed, as in C++.
- The compiler refused to generate an implicit default-constructor and copy-constructor for UDTs derived from a simple plain-old-data base UDT (that itself didn't have any constructors)
- Bin/Oct/Hex() didn't accept pointers to CONST types
- Override signature compatibility checking was broken for methods using the Pascal calling convention
- C backend: Structures containing bitfields were sometimes not emitted correctly (wrong sizeof()), so for now they will be emitted as simple byte arrays. This is bad for -g debug info of course, but that can be fixed in the future when FB's bitfields have been made compatible to GCC's, and the C backend can emit them as-is, without having to worry about layout differences.
- #733: The -> operator couldn't be applied to parenthesized UDT expressions even if overloaded for that UDT
- On Win32, wrong code could be generated when returning complex structures from functions: Under -gen gas, they could be incorrectly returned in registers (if small enough), if they became complex only thanks to the addition of implicit members. Besides being ABI-incompatible to GCC/MSVC, this could also lead to missing destructor calls.
- C backend: stdcall functions returning non-trivial UDTs had the wrong @N stdcall suffix (the hidden result pointer parameter was calculated into it, but shouldn't be)
- 0.90.0 regression: Some cases of binary operations involving unsigned operands and constants could cause the compiler to show "implicit conversion" warnings due to internal transformations, for example: dim as uinteger a, b : print a - (b - 1)
- Bad code generated for temporary variable destruction in local array initializers: temporary strings or UDTs with destructors could be destroyed before first used
- #728: Buggy overload resolution for Byval As Const parameters
- LSET / RSET were aborting when the rhs was an empty var-len string
- #739: ASM backend: The compiler allocated unused stack space for dynamic arrays (besides the array descriptor), based on the array element data type size. This was not only a waste of memory, but could also lead to stack overflow crashes if the array element data type was very big.
- #736: Format() overflow when significand (after scaling to 19 digits) is 2^63 or greater
- Format() overflow on very small numbers, trying to scale them by excessively large powers of 10
- 0.24.0 regression: cgi-util.bi was missing
- Format() was adding an extra digit before the decimal point in scientific notation when rounding up to the next power of 10


Version 0.90.1:

[fixed]
- Potential internal errors in Unix rtlib during SIGWINCH signal handling, due to calls to non-async-signal-safe functions
- Any input on stdin could break the Unix rtlib's escape sequence communication with the terminal, e.g. typing very fast at an Input prompt
- #679: WINDOW width/height were losing precision on very small Single values
- Taking the address of a PEEK, [] indexing, or * dereferencing expression could ignore the PEEK/indexing/derefenced data type (e.g. "@peek( integer, myptr )" returned myptr's type instead of an INTEGER PTR, and "@string[index]" returned a ZSTRING PTR instead of an UBYTE PTR). This could also break WITH when used on a PEEK expression.
- C backend: Passing @proc (taking address of procedures) expressions to BYREF parameters caused bad C code to be generated
- Pointer arithmetic on procedure pointers is now disallowed. It is not meaningful, because procedures do not have a fixed size and are not arranged like array elements.
- 0.90.0 regression: A bug in array index parsing could cause the compiler to crash due to arrays being used without index, instead of showing an error message
- 0.90.0 regression: ON GOTO was broken due to the compiler generating bad jump tables for it
- 0.90.0 regression: Some Win32 API libs were missing (e.g. libstrmiids.dll.a)


Version 0.90.0 (former 0.25.0):

[changed]
- -c, -r and -pp options will now complement each-other when used together, instead of partially overwriting each-other and thus causing weird behaviour
- getkey()/inkey() under Linux X11 graphics mode will now return the FB extended keycode for DELETE (&h53FF or &hFF &h53) instead of ASCII DEL (&h7F), for consistency with console-mode and other platforms
- ScreenEvent() won't return extended keycodes anymore in the EVENT.ascii field under the Linux X11 graphics driver
- Removed compile-time errors for float division by constant zero; it will result in INF again, for consistency with the evaluation at run-time
- Overflows when converting constants to SINGLE/DOUBLE won't cause "math overflow" errors anymore
- Overflows in constant conversions to SINGLE will now trigger "overflow in constant conversion" warnings, like conversions to integer types do
- Constant conversions to DOUBLE are not checked for overflows anymore, since DOUBLE can hold all SINGLE/INTEGER/LONGINT values (although, with varying precision)
- Doing "udtvar.constructor( ... )" or "udtvar.destructor( )" won't automatically add a constructor/destructor anymore, but instead show an error
- The C backend now emits expressions in-line instead of using #defines, and also avoids many unnecessary casts, producing much nicer C code
- fbc now uses a custom COFF/ELF32 reader instead of libbfd for the objinfo feature
- fbc will now also read out compile-time information from libs passed as libfoo.a instead of -l foo or #inclib "foo"
- Linux fbc will now prefer linking with libtinfo over libncurses, if available (depending on the distro, ncurses may be present as one libncurses, or with separate libtinfo; but either way FB only needs the libtinfo part)
- ASM backend: Floating point constants are now emitted in form of their raw byte representation, for better precision than when using STR() to emit them as rounded floating point number literals
- crt/stdio.bi now declares rename() instead of rename_()
- Property methods using an explicit ALIAS now respect that alias and do not append __get__ or __set__ anymore
- #637: Assert[Warn]() messages go to stderr now, rather than to the FB screen (because that might be about to be closed)
- LBound/UBound( array, 0 ) now returns 1 and the dimension count, it is no longer the same as LBound/UBound( array, 1 )
- #if/#elseif expressions now recognize declared identifiers (for example a constant FOO will be expanded to its value, instead of being treated as a "FOO" string)
- Unary/binary operations won't return enums anymore; any enum operands will be converted to integer before the operation. (with math operations, the result can be any integer value, and the operand enum won't necessarily include a constant corresponding to that value. And also, if the operands are from different enums, the compiler wouldn't know which one to use as the result type)
- Unary/binary operations will now convert smaller operands to INTEGERs before the operation (note: thus, UBYTE becomes INTEGER now instead of UINTEGER, and also SHORT/USHORT operations will return an INTEGER now)
- -pp will now preserve #inclib, #libpath, #lang, $ meta commands, msbitfields #pragmas, and #undef (except on macros which, unlike other symbols, won't be preserved anyways), in order to allow the output file to be compiled just like the original
- -o in combination with -pp will now set the output file name for the preprocessed version of the associated input module
- SCREENRES is now a normal function instead of a quirk statement
- BSAVE now (by default) saves 32-bit .bmp files in 32-bit screen modes instead of 24-bit files

[added]

- fbc -print x option (named after the fbc -x option), to display the output binary/library file name, as far as it's known based on other input, i.e. -dll, -lib, -m, and input files. For example, on Win32/DOS "fbc -m foo -print x" will give "foo.exe", while "fbc -print x" alone will only print ".exe" (this can be used to query the executable file extension)

- LBound/UBound() on fixed-size arrays with constant dimension argument (or none at all) will now be compile-time constants
- IIF now allows different types to be mixed, for example iif( condition, mybyte, myinteger ), the result type is the bigger type
- #if/#elseif now accept all kinds of constant expressions that would be accepted in other places (e.g. in PRINT or in constant declarations)
- preprocessor #assert statement
- INTEGER<n> / UINTEGER<n> / C[U]INT<n>, where n is 8/16/32/64, for allowing to choose integer types of a specific size
- CVI<n> / MKI<n>, where n is 16/32/64, to allow bit conversions of a specific size
- type<UDT>( ).field is now possible, as an alternative to (type<UDT>( )).field
- bpp parameter on BSAVE, to request a BMP bit depth
- TYPEOF() can now also be used directly on SUB|FUNCTION(...) function pointer types

- internal error in ThreadCall parser, potentially causing compiler crashes or miscompilation
- Warnings could still be shown even after the "Too many errors, exiting" message

- #3571432: LIB "" crashed the compiler
- ASM backend: -NaN float constants were emitted as +NaN
- C backend: Local UDT declarations were emitted in the scope they were first used, not where they were declared
- C backend: DATA statement declarations could be emitted in the wrong order, causing gcc errors
- C backend: Static variables with destructors were emitted as locals despite needing to be visible to destructor wrapper functions

- #644: C backend: Local variables from unused PRIVATE procedures could be falsely emitted as globals
- Static variables from unused PRIVATE procedures could still be emitted even though the procedure was not
- Any temporary variables from parameter initializers were only allocated in the main() scope, instead of being duplicated into each scope context where the initializer expression was used
- -g STABS emitter did not explicitly emit the toplevel file name again after emitting #include file blocks, causing valgrind to get confused about following procedures' parent file
- va_first() on a BYVAL non-trivial UDT parameter (which is implicitly passed BYREF) could return the wrong pointer (it assumed BYVAL but implicitly it was BYREF)
- Compiler crash on some cases of nested type initializers
- Hidden temporary variables could be made STATIC in procedures marked STATIC (making all locals STATIC), leading to hidden bugs with multi-threading or recursion. Affected constructs: SELECT CASE, SELECT CASE AS CONST, WITH blocks, QB-style error handling, string concatenation, ON ... GOTO, FOR loops, temporary variables used by the ASM backend when spilling registers
- WINPUT() did not allow a # like INPUT() does, as in [W]INPUT( bytes, #filenum )
- Screen[Res] and ThreadCreate() no longer worked on Windows 9x since 0.24, because they called msvcrt's _beginthreadex() with the last parameter being NULL
- Placement "NEW(a)" didn't require the expression to be in parentheses, allowing "NEW (a) + b" etc.
- "new[expr] UDT" evaluated "expr" multiple times even if contained function calls, if the memory buffer was just being cleared (i.e. UDT had no default constructor and "{ ANY }" wasn't used)

- When initializing an UDT parameter with any expression except for type(), an extra temporary copy was created everywhere the initializer was inserted
- type<const UDT>() was not parsed as constructor call if the UDT had constructors, but as plain UDT initializer instead, due to the CONST

- BYREF AS ANY|forward-reference parameters are no longer allowed to have parameter initializers
- type() is no longer allowed as argument to BYREF AS ANY parameters
- Single-line IF statements were not opening a scope, exposing potentially uninitialised variables declared within to outside code, e.g. "IF 0 THEN DIM s AS STRING ENDIF:  PRINT s"

- SELECT blocks will no longer allow other statements in between the SELECT header and the first CASE statement
- lang qb didn't allow DEF___ statements inside procedures/compounds despite the change in 0.21.0

- The compiler allowed a single "ASM" token to appear at end-of-file (without newline following), without showing an "expected END ASM" error
- C backend: fbc always passed a "wrong" -mtune option to gcc, that didn't match what was given to fbc's -arch option
- The -exx CPU type check could look for invalid CPU families under any -arch option except 386/486/586/686
- The type checks for assignments involving *zstringptr or *wstringptr expressions could be buggy, for example causing "*zstringptr = float" assignments to be disallowed under the C backend
- #577: The compiler allowed assignments between string and *byteptr expressions, as if they were string and *zstringptr expressions
- #508: The internal allocate/callocate/reallocate declarations didn't use an unsigned parameter like the real malloc/calloc/realloc functions, causing type mismatches with the C backend
- #if typeof( myintegerpointer ) = "INTEGER PTR" will now work

- #661: -gen gcc will now invoke gcc with -m32 now, allowing it to work with multi-lib gcc that defaults to 64bit (usually on 64bit systems)
- #662: zstring ptrs were indexed as char* instead of ubyte*
- #641: Type casting of an expression to the same data type but with CONSTs added or removed was being ignored

- #621: Parsing & overloading checks for argument lists of PASCAL procedures/constructors was broken
- C backend: Backslashes in wstring literals were not escaped when emitting
- Binary operation result types are more consistent now, for example "integer + uinteger" will now return a uinteger, just like "uinteger + integer"
- Win32: When using a graphics window nearly as big as or bigger than the available screen space, the graphics window's size could be truncated by the system, for example causing GetMouse to return coordinates that didn't match the actual mouse position, at least under the DirectX driver. FB will now handle WM_GETMINMAXINFO to prevent the system from making the window smaller than requested.
- Anonymous type() couldn't be used in initializers for UDTs with constructors
- Comparison Operator overloads accepting two intrinsic-type parameters could be declared (but not used)

- DOS COMMAND(0) was giving '/' for the path separator instead of '\'
- DOS CURDIR and COMMAND(0) return values had a lower-case drive letter
- EXEPATH() on all platforms was omitting the slash at the end of root paths, resulting in a relative or missing path (e.g. "X:\" -> "X:" or "/" -> "")
- Hang in exec()/chain() functions on Linux if the target executable isn't found (observed with musl libc)
- Minor scaling bug when using BSAVE to save 16-bit images to BMP, causing barely visible changes and the potential loss of the least significant green bit
- Potential crash (read-after-free) in gfxlib2 X11 OpenGL backend initialization


Version 0.24.0:

[changed]
- add a "special exception" to gfxlib2 license to allow linking into executables under more relaxed terms (the same as the rtlib)
- -target option now accepts system triplets (known from gcc/binutils)
- By default even the non-standalone fbc is now relocatable and relies on exepath()
- fbc no longer includes full ldscripts, a supplemental snippet (fbextra.x) is passed to the linker instead (except for the DOS/DJGPP version which still relies on a modified ldscript)
- __FB_UNIX__ and __FB_PCOS__ now work like the other target defines (check via #ifdef)
- All cross-compilation targets are now always enabled in the compiler
- -o now also affects .rc and .xpm input files (useful to change the file names of the temporary objects)
- -o must now clearly be specified in front or behind of the corresponding input file, for example: "fbc 1.bas 2.bas -o 1.o -o 2.o" no longer works, but "fbc -o 1.o 1.bas" is possible now
- -x used with -lib now sets the library file name
- "No newline at end of file" warning removed

- The bitwise NOT operator is now mangled as bitwise not ('~' in C++) instead of logical negation ('!' in C++)
- The '= ANY' intializer on variables or fields will now prevent the default constructor call (if any), instead of generating a warning message, requiring the variable or field to be initialized with an explicit constructor call. It still won't affect destructor calls though.
- #3051592: crt/errno.bi now uses __errno_location() to access errno on Linux
- The NAKED keyword is now disallowed under -gen gcc because gcc doesn't support naked functions on x86
- DELETE on something that's not a pointer now always triggers an error, not just a warning
- The -target option is no longer case-sensitive
- Linux standalone fbc won't try to use tools from PATH anymore

- x11 gfx driver: let the window manager pick the window position (DrV)
- '&' string concatenation will not pad positive numbers, even in lang qb (counting_pine)
- removed runtime check for dialect in BLOAD/IMAGECREATE/GET so they will respect the dialect where used even if main module is compiled under a different dialect.  qb/fblite uses old header and fb uses new-header. (jeffm)
- lang qb can now use all the OPTIONs fblite can, e.g. OPTION STATIC|BYVAL|... (counting_pine)
- CVD / CVS may no longer be constant, since binary equivalence cannot be guaranteed at compile-time (counting_pine)

[changed]
- the default calling convention of variables has changed in -lang FB. UDT's (including strings) will default to BYREF, all else will default to BYVAL (cha0s)
- TYPEs with default constructor/destructors or methods had to be allowed on the module level. This affects you if you define a TYPE inside a function with any functions inside the TYPE, or any child objects that have constructors or destructors. This includes elements 'as string', since they need constructors and destructors to initialize and clean up memory (cha0s)
- ODE 0.8 headers, import library, and examples, thanks D.J.Peters, (jeffm)

[added]
- configure option for --disable-objinfo to allow building and using fbc with a broader range of binutils (jeffm)

[fixed]
- #1735413 - UDT initialization would fail if the initialization expression was surrounded in parenthesis, due to the udt = (elm, elm) syntax. it will now fallback to check if the first expression encountered matches the udt type, if so, it will attempt a ctor call/assign. (cha0s)
- #1734192 - UDT initialization with unions should have been checking the first union element against the given expresssion. (cha0s)
- Mangling params taking FB arrays wasn't unique from params as the array's datatype. Recompile any libraries/linked objects taking arrays as parameters.
- ThreadCreate was accepting literally "any" pointer at its first parameter. Added a mechanism for building function pointer symbols (to check against, say the first arg passed to ThreadCreate) at the rtl symbol initializer. (cha0s)
- #1713886 - symbols in FOR had the temp bit stripped out to make scope jumping work, but it can be added in later, otherwise the branch checker will get confused (cha0s)
- #1696229(part one!) - constant symbols in TYPEs could be modified with disastrous results. (cha0s)


Version 0.18.0 Beta:

[changed]
- include file and import library for libcurl 7.15.4 (jeffm)
- #1723533 - MK* had to be reverted, it will not evaluate constant numeric expressions to constant literal expressions anymore (it will behave like it used to), because of the NULL-terminated nature of literal strings, sorry (CV* still evaluates to constants(arguably much more important ;)) (cha0s)
- the overload resolution wasn't normalizing the total sum of its matching args (cha0s)
- gfxlib creates its windows with THREAD_PRIORITY_ABOVE_NORMAL again, without it was jerky (cha0s)

  IMPORTANT: this is a binary incompatible change - you must recompile any code that uses SETMOUSE or GETMOUSE (DrV)
- a vararg procedure can now be defined in a TYPE, it has to be unique (cha0s)
- a second STEP in PUT, see the wiki for details (cha0s)

[fixed]

- "as ANY" as being allowed on TYPE members(cha0s)
- bogus field accesses should have been creating a fake symbol (cha0s)

- main GFX window on win32 captures mouse input to allow out of window mouse button releases (jeffm)
- the arguments passed to overloaded functions that contain enum parameters must be enum's too, no auto-coercion will
  be done from integer/floating-point, to support operator overloading (v1c)

- thanks to the new GET/PUT header, pixel data now starts at offset 32 and pixel rows are paragraph-aligned (the pitch of
  a row will always be a multiple of 16 bytes)
- the Lua headers were replaced by machine-translated ones, some function/macro names were changed by the Lua authors since the last version;
  also, the luauxlib.bi header was renamed to lauxlib.bi to match the original C one (v1c)
- SetDate and SetTime now return an error when they fail (DrV)
- internal profiler removed, profiling is now done externally using GPROF (jeffm)
- -lang qb now skips UDT alignment by default (cha0s)

Version 0.14 Beta:

[changed]
- IMPORTANT: to fully support pointer type-casting, now every time a pointer is updated, the expression will be
  multiplied by the pointer type, as done in C, so if you had: "dim p as integer ptr:" "p += len( integer )", now it
  must be changed to "p += 1"
- to make BYVAL AS STRING arguments more safe, as they are allowed in FB functions since version 0.13, if not
  passing pointers or numeric values such as NULL or 0, the BYVAL modifier will have to be used now (v1c)
- _main will be always the entry-point from now, to be more compatible with statically linked C libraries and
  to remove the DOS and Xbox temporary object creation "hack". Because of that, if compiling and not linking
  objects files, the -m command-line option must be used to tell the compiler which module will be the main
  one (v1c)
- the DllMain function is not needed anymore in the Windows version, just declare the exports and remove the
  DllMain function, it won't be ever called (v1c)
- the module-level code of non-main modules will now be always executed (before the main module), no REDIM's or
  such will be missed as it used to happen in QB. Implicit module initialization can be done now as in Pascal,
  just add any code to the module-level scope (ie: outside any function) (v1c)
- the array descriptors had to be modified, if you have any DLL's compiled with old versions, please recompile
  them with this new version if passing arrays by descriptor to functions (v1c)
- the intrinsic functions SIN, COS, TAN, ATN, SQR, INT and ATAN2 are now implemented as inline and will be
  evaluated at compile-time when constants are used as parameters (v1c)
- macro text will be expanded on comments emited when the -g command-line option is used (v1c)
- multiple strings concatenation such as "a = b + c + d + ..." will be converted to
  "a = b: a += c: a += d: ...", giving a speed up, because no temporary dynamic strings will be used (v1c)
- speeded up PUT routine when using PSET/PRESET/AND/OR/XOR drawing mode (lillo)
- the compiler is now a bit easier to be cross-compiled using the Win32 version (v1c)
- SCREENINFO does not return a pointer to an internal structure anymore, and if called before a gfx mode has
  been set, it returns infos on the desktop resolution/depth. See gfxlib.txt for more info (lillo)
- COLOR will now return the current/last color attributes as: (forecolor or (backcolor shl 16)) (v1c)
- WIDTH will now return the current/last dimensions as: (width or (height shl 16)) (v1c)
- LOCATE will now return the current/last cursor state as: (x or (y shl 8) or (visible shl 16)) (lillo)

  versions of the GNU binutils are available and if all the libraries needed are installed (v1c)
- #UNDEF will now work with any symbol kind, not defines only (v1c)

[added]

- custom blenders for PUT: pass mode CUSTOM,blender, where blender is a pointer to a function of the form
  "function blender ( byval src as uinteger, byval dest as uinteger ) as uinteger". This will be called for each pixel
  and must return the new blended pixel to be drawn (lillo)

  they are just a zstring with unknown size (v1c)
- gfxlib internal data (default fonts and palettes) is now compressed in the EXE and decompressed on the fly using a tiny LZW codec,

Version 0.12 Beta:

[changed]
- IMPORTANT: now to declare functions on DLL's that will be exported, the EXPORT clause must be used, as global
  functions won't be automatically exported anymore, because that would make it hard to write DLL's with
  multiple modules where not all global functions should be exported (v1ctor)
- IMPORTANT: the format of the internal string descriptor was modified to speed up concatenation of large strings,
  so you MUST recompile all the old code, don't reuse object files compiled with older versions (below v0.12b) and
  rebuild DLL's created in FB if they return or process STRING's passed to/from client EXE's (v1c)
- Linux port does not use ncurses anymore, but its own internal lowlevel routines for console access.
  Apart from no ncurses dependency, this means faster console output (also under X11), no screen clearing
  at programs startup and proper colors support under X11. Compatibility issues may rise though, so
  feedback is welcome (lillo)
- PEEKS, PEEKI, POKES, POKEI keywords removed, use now the new syntax as "PEEK( data type, expression )" or
  "POKE data ype, expression, expression" to peek/poke different data types than BYTE, that's the default one (v1c)
- many Allegro's globals like al_screen, al_rgb had the "al_" prefix removed, they are now as the originals (v1c)
- Gfx GET and PUT now support both arrays and generic pointers as data holders (lillo)
- white-spaces are now preserved for ASM blocks and #DEFINE's (v1c)
- Linux port install script will now warn users if not run with root priviledges (lillo)
- the range of console-mode background colors is now 0 to 15 in DOS and Windows, 'cause Nex wanted that :) (v1c)
- generated EXEs size can now be up to 5-6K smaller than before (lillo)
- empty statements like ":foo=1::bar=2:" are now accepted, "if foo then:bar:else:foo" will work too (v1c)
- DIM|REDIM array w/o explicit dimensions is not allowed anymore inside procs, as the descriptor size is unknown (v1c)
- RGB is now an intrinsic macro, not a function (so no UDT's called RGB are allowed anymore) (v1c)
- symbols can now start with an underscore as in "_1234 = 1234" (v1c)
- local labels can now have the same name in different procs (v1c)

[added]
- resource files support on Windows, just add the .rc's or .res' to the list, they will be automatically
  compiled -- the Windows C headers were also added, so complex scripts (ie: dialogs and menus) can be
  used too (DrV)
- XPM icon resource files support on Linux. As with Windows resource, just pass the .xpm file to
  the commandline and the executable will sport a fb_program_icon symbol holding the XPM data.
  If using gfxlib, this is automatically used to set the window icon (lillo)
- built-in multiplatform threading functions (lillo)
- "operator =" shorthand, as in "a += b * c" (v1ctor)

- SCREENPTR was always returning the pointer to the visible page memory instead of the working page (lillo)
- palette handling via INP/OUT emulation was producing bad colors (Sterling)
- various fixes to the X11 internal gfx driver: was not working if the X server was running in 24bpp mode, mouse

- PRINT and WRITE shouldn't allow UDT's as parameter, same with INPUT (v1c)
- COMMON arrays wouldn't be redimensioned when a REDIM was used (v1c)
- integer division and modulo could gen bad code if pointers or indexes were used with EAX as the index reg (v1c)
- base for non base-0 arrays with more than 2 dimensions was being wrongly calculated (v1c)
- d! = cbyte( d! ) would gen bad code at EMIT if the SI or DI registers were used as source (v1c)
- #define's would be checked inside $include and $inclib if ' was used as delimiter (v1c)


Version 0.11 Beta:

[changed]
- the internal GFX library is now the former alternative one written by lillo, many thanks to Sterling
  for making the first version, he started working on it even before FB was released -- if you prefer to
  continue using it, the sources still on CVS at sf.net (src/gfxlib), just build the library and rewrite
  the libfbgfx.a file at \lib, it contains no PAINT or DRAW, nor low-res screen modes, but everything
  else stills functional - the SCREEN arguments are different, pay attention
- new OpenGL header translated by Rel to work better with pointers, there are no more BYREF arguments,
  use @ or varptr() to get the address of variables and arrays when the argument is a BYVAL ... PTR (v1c)
- fmod and BASS headers: all BYREF arguments changed to BYVAL ... PTR to work better with pointers (v1c)
- new SDL headers translated by Edmond Leung, no changes needed on user's code (v1c)
- fixed-len strings on arrays can now be passed as parameter to functions (v1c)
- array fields can now be passed by descriptor, as in "array(idx).arrayfield()" (v1c)

- ERASE now accepts non-dynamic arrays and fills them with 0's (v1c)
- the crt dll on Win32 is now msvcrt.dll instead of crtdll.dll, to be able to statically link to libs
  compiled with VC 5/6 and Mingw (crtdll is not supported by M$ anymore), you can use the new -nostdlibs
  option to set a different lib (like crtdll) if you really need that -- ie: plain vanilla Windows 95/osr2
  doesn't come with msvcrt.dll installed (it can be found at M$'s site) (v1c)
