Version 0.20.0 Beta:
[changed]
- the "-r" compiler switch will now prevent FBC compiling/linking the asm, unless overridden by "-c". Its old behavior is now given by "-R"
(counting_pine)
- update FreeImage header to v3.10 and .def files for Win32 (cha0s)
- 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)
- binary operator overload resolution logic: Now an operator is only eligible if at least one side of the expression matches the candidate's
parameter list exactly, without implicit coercion/casting. (cha0s)
- the default aspect ratio for CIRCLE is now 1.0 in SCREENRES modes (counting_pine)
- CIRCLE should get its size from just the horizontal scale of the WINDOW/VIEW viewport - its ratio should be unaffected (counting_pine)
- DIR may now accept a byref [u]integer for out_attrib (byval integer ptrs are still allowed) (counting_pine)
- SCREENLOCK/SCREENUNLOCK now keep a reference count internally to allow them to be used inside functions without unlocking a global lock
(DrV)
- linux: only specify linker script path for standalone builds (fixes lib path problems on x86-64) (DrV)
- removed mini.bi, example, and wrapper (jeffm)
- BLOAD now supports 15, 16, and 32-bpp BMP files, alpha in 32-bpp BMP files (BITMAPV4/V5HEADER only), arbitrary BI_BITFIELDS bitfields, and
OS/2 BMP files (DrV)
[added]
- #lang directive and $lang metacommand to set compiler dialect from source code (jeffm)
- IMAGEINFO function, for retrieving useful information about FB gfx buffers (counting_pine)
- warning message when string literals aren't closed with a quote (counting_pine)
- C emitter: GOSUB and ON GOSUB using setjmp/longjmp (jeffm)
- "-z gosub-setjmp" command line switch will select setjmp/longjmp implementation even if the backend is ASM (jeffm)
- fblite, qb: OPTION GOSUB, OPTION NOGOSUB to enable/disable GOSUB support. State can be checked with the intrinsic define
__FB_OPTION_GOSUB__ (jeffm)
- #1899251 (feature request) - RETURN without GOSUB runtime error check for both ASM and setjmp/longjump implementations of GOSUB (jeffm)
- ANDALSO and ORELSE operators (yetifoot)
- "-R", "-C" switches, to tell FBC to retain the asm and object files (if written), respectively (counting_pine)
- SSE/SSE2 instructions in x86 emitter for floating point math (Bryan Stoeberl)
- "-fpu FPU|SSE" command line switch (Bryan Stoeberl)
- OPTION("FPU|SSE") to specify proc return method (Bryan Stoeberl)
- CPU check for SSE applications (Bryan Stoeberl)
- #1515157 (feature request) - GET# returns number of bytes read in 5th byref parameter (jeffm)
- improved error messages for GET#/PUT# - warn if passing a pointer as source/destination, error if elements is given on string or array
(jeffm)
[fixed]
- wstring VAL*s were accepting invalid characters in hex/oct/bin numbers (counting_pine)
- PCOPY wouldn't copy graphics screens higher than the max console page (counting_pine)
- VAL on non-win32 platforms was only accepting 'e' (not 'd') as an exponent specifier (counting_pine)
- VAL* was saturating instead of overflowing large numbers in some cases (counting_pine)
- wstring VAL was truncating hex/oct/bin numbers to 32 bits (counting_pine)
- constant ASC expressions were returning signed integers instead of uintegers (counting_pine)
- STR should pad numbers if and only if it is called from a lang qb module, even in multi-module programs (counting_pine)
- #1933706 - !"\a" was not working correctly (yetifoot)
- #1914051 - Some unhandled escape sequences were being allowed through (yetifoot)
- #1861363 - gfxlib win32 gdi driver was using the alpha_remover_blitter on depths < 32 bits (jeffm)
- #1931922 - lang qb: prototypes for overloaded procdefs were not being added correctly (jeffm)
- lang qb/fblite was allowing dups of unsuffixed variables having different types (jeffm)
- lang qb: LEN() was allowing UDT's and typedef's (jeffm)
- GET/PUT were discounting padding at the end of UDTs (counting_pine)
- escaped strings in unicode sources were crashing the compiler (counting_pine)
- WRITE wouldn't append a comma or newline to empty strings (counting_pine)
- serial driver on linux wasn't handling device names correctly (jeffm)
- #1957281 - PALETTE in Screen 12 should work like in Screen 13 (counting_pine)
- string literals in #defines couldn't contain double-quotes (counting_pine)
- Three-digit decimal escape sequences would swallow the next character if it was decimal as well (counting_pine)
- #1914051 - !"\x..", !"\X.." escape sequences weren't working properly (counting_pine)
- #1961732 - LSET wasn't accepting dereferenced vars for the destination (counting_pine)
- RSET was allowing constants to be modified (counting_pine)
- CPTR() will generate a warning if casting to anything but pointer, integer, or enum and will generate a pedantic warning when casting to
anything but pointer (jeffm)
- #2004439 - LSET/RSET was not deleting temporary string descriptors for the destination (jeffm)
- #1914763 - LINE INPUT to a WSTRING variable on an ascii text file was failing if last line of file had no end of line character (jeffm)
- #1979795 - GETMOUSE in Win32 GFX driver was not clearing the status of the XBUTTON's correctly (jeffm)
- #2016487 - inc/win/vfw.bi - Changed "Delete" to "Delete__" and ported the remaining IC* AVI* and MCI* defines (jeffm)
- "TYPE FOO : AS INTEGER BAR : END TYPE" wasn't allowed because a bitfield value was expected to follow "BAR : " (counting_pine)
- Casting ops that called a function (e.g. CSNG("..."), CLNG/CVL ) weren't necessarily returning the exact desired type (counting_pine)
- #1872418 - Win32 GFX updater thread was calling rtlib string conversion unsafely in the non-threaded version of the rtlib (jeffm)
- internal: lang qb/fblite - error recovery for duplicate defs could cause a out of bounds array access in symbGetDefType because the
temporary name begins with '.' (jeffm)
- #2038666 - lang qb: variables with the same name as a keyword must have a suffix (jeffm)
