Move the TinyCC/Windows ARM64 Interlocked workaround from the semlock call site into the bundled WinAPI header. This keeps tcc.h using the normal Interlocked API while avoiding unresolved Interlocked imports when tcc -run self-compiles on Windows ARM64.
Update lib/bt-exe.c as well so its ARM64 runtime object does not define a second InterlockedExchange fallback now provided by winnt.h.
tcc.c:
- be nice to leak checkers
tcctools.c:
- remove unused TCCState params
tccrun.c:
- call bound_exit() after signals to let it free mem
tccelf.c:
- use section_add() instead of section_ptr_add() when
more appropriate
tccpp.c:
- use size_t to align tal_header naturally
- 'POINTER_SIZE' and 'PTR_SIZE' in the same source is confusing
- "char file_name[TAL_DEBUG_FILE_LEN + 1];" looks silly.
- next_nomacro(): skip UTF8 BOM at BOF
tccgen.c:
- get rid of STMT_EXPR clause on top of block
- warn with useless type like 'int;'
- move skip()'s in block() for better error line-info
- BIT_SIZE bits are meaningful only with VT_BITFIELD
(not with enums for example)
workflow/test-win32:
- build with MSVC using build-tcc.bat also
alloca.S:
- fix 'off by one' problem on win32 (must touch current page
too because the 'push %edx' at the end could touch the next page)
- must not align greater than 4 when used for struct args
(i386-gen.c:gfunc_call())
libtcc.c:
- accept -g1dwarf (dwarf output, only line info)
- Use runtime function for conversion
- Also initialize fp with tcc -run on windows
This fixes a bug where
double x = 1.0;
double y = 1.0000000000000001;
double z = x < y ? 0 : sqrt (x*x - y*y);
caused a bad sqrt because rounding precision for the x < y comparison
was different to the one used within the sqrt function.
This also fixes a bug where
printf("%d, %d", (int)pow(10, 2), (int)pow(10, 2));
would print
100, 99
