tccpe.c:
- fix arm64 unwind codes (to make native set/longjmp() work)
sizeof(RUNTIME_FUNCTION) is 8 on arm64 in the first place
no need to note stack slots if we don't save any registers anyway
arm64-gen.c:
- fix long double reg-move
- fix arm64_hfa() for structs with float arrays
- gfunc_prolog(): setup stackframe eariler (simplifies unwind codes)
- new function gv_addr(RC);
win32/include/setjmp.h:
- provide correct definition for setjmo() (frameoffset = 224)
tccasm.c:
- support ".quad" with symbol & relocation
- support ".size"
- fix ". - symbol" arithmetic
win32/lib/crt1.c and win32/include/stdlib.h:
- do not write to __argc/__argv which reside in msvcrt.dll
(msvcrt.dll on arm64 does not like that, crashes on unload)
tcc.c,libtcc.c:
- new functions tcc_fopen/fclose to avoid different stdio unstances
in tcc.exe & libtcc.dll
tests & github workflow:
- add test-win32.bat to run tests with a tcc compiled by build-tcc.bat
- add msvcrt_start.c for gcc/clang to use the same runtime as tcc
the problem is that newer gcc as well as clang and cl are
linking to newer runtimes (such as UCRT) that have partially
different printf format behavior which makes tcctest fail.
the solution here is to force these compilers to link with
msvcrt.dll just like tcc.
Also, there is no gcc on arm64-win32 currently at all.
Anyway, this approach to running the github CI tests
does not require msys2. But It does rely on gnumake
as well as on some 'sh' shell though which seems to be
installed somewhere (maybe it is the one from git).
tested on win32/64 to pass the tests when enabled
- libtcc.c :
let tcc define __leading_underscore if enabled
tcc_add_symbol() : add _ automatically
- tccelf.c : remove tcc_get_symbol_err(), find_c_sym()
currently symbol length is limited to 256 in several
places, so we can use a fixed local buffer for now as well.
- win32/lib/crtinit.c : new file for init/fini
- lib/*.S, tests7* : use __leading_underscore
- bt-log.c: this file wont work relibaly if compiled with gcc
- libtcc.c/tccpp.c: fix -U option for multiple input files
- libtcc: remove decl of tcc_add_crt() for PE
- tcc.h: define __i386__ and __x86_64__ for msvc
- tcc.h: undef __attribute__ for __TINYC__ on gnu/linux platforms
- tccelf.c: disable prepare_dynamic_rel unless x86/x64
- tccpe.c: construct rather than predefine PE section flags
- tccpp.c: (alt.) fix access of dead stack variable after error/longjmp
- x86_64-gen.c: fix func_alloca chain for nocode_wanted
- tccpp.c/tccgen.c: improve file:line info for inline functions
- winapi/winnt.h: correct position for DECLSPEC_ALIGN attribute
- win32/lib/crt: simplify top exception handler (needed for signal)
- arm64-gen.c: remove dprintf left from VT_CMP commit
- tccgen.c: limit binary scan with gcase to > 8 (= smaller code)
- tccgen.c: call save_regs(4) in gen_opl for cmp-ops (see test in tcctest.c)
tccgen.c:
doubles need to be aligned, on ARM. The section_reserve()
in init_putv does not do that.
-D ONE_SOURCE: is now the default and not longer needed. Also,
tcc.h now sets the default native target. These both make
compiling tcc simple as "gcc tcc.c -o tcc -ldl" again.
arm-asm.c:
enable pseudo asm also for inline asm
tests/tests2/Makefile:
disable bitfield tests except on windows and x86_64
and don't generate-always
tcc.c:
fix a loop with -dt on errors
configure:
print compiler version (as recognized)
tccpp.c:
actually define symbols for tcc -dt
clear static variables (needed for -dt or libtcc usage)
96_nodata_wanted.c:
use __label__ instead of asm
lib/files:
use native symbols (__i386__ etc.) instead of TCC_TARGET_...
To make this the default, enable this line in libtcc.c:tcc_new:
#if defined(TCC_TARGET_PE) && 0
s->leading_underscore = 1;
and then recompile tcc and also libtcc1.a
This enables native unwind semantics with longjmp on
win64 by putting an entry into the .pdata section for
each compiled fuction.
Also, the function now use a fixed stack and store arguments
into X(%rsp) rather than using push.
