Currently used only with 'tcc_compile_sem' to protect
tcc_compile(), but can be used with other semaphores
Also fix deadlock when tcc_enter_state() is called
recursively for the same state, for example with
tcc_warning() from #pragma comment(option,"...")
Also:
- libtcc.c: error1(): use cstr_[v]printf()
- tcc.h: set TCC_USING_DOUBLE_FOR_LDOUBLE for macho-arm64
(rather than for macho-X86_64)
- tcc.h: define TCC_TARGET_MACHO on __APPLE__ by default
- tcc.h: cleanup TCCState, move DEFASM token stuff to tcctok.h
- tccgen.c: more static
- Makefile/tcc.c: review githash
- tccpe/tcctools: use read() instead of fgets() in pe_load_def()
(all files opened by tcc for reading are now read via 'int fd')
- configure/win32: don't preset CONFIG_TCCDIR (to allow to override it)
- tcc.c -bench: do not include output/run-time

only one set_flag() function required
* can now turn off specific errors: -Werror -Wno-error=option
* new interface: tcc_warning_c(warn_option)("format", args...);
* new warning: -Wdiscarded-qualifiers (on by default)
* new variable 'warn_all' for conditional warnings with -Wall
see also the tests
configure:
- re-enable apple M1-arm64
- however, with --cpu=x86_64, set -arch in CFLAGS/LDFLAGS too
(assume rosetta)
Makefile:
- re-enable osx cross-test (Please do not disable tests)
tcc.h
- set TCC_IS_NATIVE for TCC_TARGET_MACHO on __APPLE__
- apply TCC_USING_DOUBLE_FOR_LDOUBLE for x86_64-osx
libtcc.c:
- cleanup tcc_add_file_internal()
- new function char *tcc_load_text(int fd); and use it for tbd files
Supports linking using .tbd definitions found in the default installed
command-line tools SDK or Xcode.app SDK. Only for creating executables
(not yet for `tcc -run`).
Add support for some more options to generate dependency fragments.
-M is likes -MD but doesn't compile anything so the command won't fail
when just supplied a file without all the relevant libs.
-MM and -MMD are like their counterparts but skip system libs.
Note the behavior of -MD has changed to include system libs. Use -MMD
for the old behavior. This matches gcc's corresponding flags
libtcc.c: add -Wwrite-strings to -Wall
tccgen.c: ro float-consts, string-consts, ro arrays if base type is
tccpe.c: merge IAT with rodata
tccrun.c: mprotect rodata accordingly. free section data after copy
x86_64.c: do not use got for static data.
tcc -bench: show data.rw/ro
Probably STB_LOCAL should never get to put_got_entry(), and currently
it doesn't seem to happen (See "Hack Alarm" there)
Other files: use more ro-data in tinycc
tccgen.c: debug_modes
- don't waste debug function calls during normal execution.
libtcc.c:
- mem_debug: no C99 features in tcc please, for example
({compound expressions}): do not use.
tccgen.c: struct_layout:
- unaligned access is completely ok for most targets.
- Moreover the patch was triggering single byte mode even
for normal aligned access (as with tcc's SymAttr)
static Sym label: don't do this
arm-gen.c:
- use some #ifdefs to explain some code
tccpp.c:
- cleanup UCN chars
libtcc.c:
- replace openbsd library search
configure:
- cleanup strip fallouts
tccgen.c:
- expr_cond(): remove an exotic optimization that eventually
got fixed to do the contrary by a gv(RC_InT)
- pop_local_syms(): remove some args
- init_putv() : use write##le functions to avoid cross-compiler
unaligned access
- __bt_init(): remove unused param 'mode'
libtcc.c:
Fix unaligned load/store from magic3
tccgen.c:
For packed struct allways use single byte code
If field does not start at at align check it
Align stack correctly with vla
I have implemented the -ftest-coverage option. It works a bit different
from the gcc version. It output .tcov text file which looks almost the
same as a gcov file after a executable/so file is run.
Add lib/tcov.c file
Modify Makefiles to compile/install it
Add -ftest-coverage option in tcc.c/tcc.h/tcc-doc.texi
Add code to tccelf.c/tccgen.c/tccpe.c
Add gen_increment_tcov to tcc.h/*gen.c
unrelated changes:
Add sigemptyset in tccrun.c
Fix riscv64-gen.c tok_alloc label size
The small common parts within elf_output_file() aren't
worth the many #ifdefs. Also, set section sizes and
allocate section names in 2 separate functions.
tcc_define_symbol(): now only for -D on command line
include/tccdefs.h: converted to strings and compiled into
the tcc executable. Can be disabled with
./configure --config-predefs=no
In this case include/tccdefs.h is loaded at runtime. This is
default for other build-methods (build-tcc.bat) also (to avoid
some complexity).
Also:
- lib/Makefile: fix typo
- tcc.h : avoid _strto(u)i64 (for TCC on WIN98/2K)
- tccpp.h:cstr_printf() : workaround incompatible vsnprintf's
(generally faster too)
This implements support for FreeBSD on aarch64
This partial implements support on FreeBSD(32). This still needs fixing
i386_gen.c because small structures on this target are passed in registers.
Add aligned 16 to __int128_t for FreeBSD
Support __i386__ on FreeBSD/NetBSD
Fix testcase 115 on FreeBSD/NetBSD
Disable testcase 116 on *BSD* because TLS_FUNC/TLS_VAR not set in bcheck.c
Remove FreeBSD/FreeBSD_kernel code from tccelf.c
Fix crtbegin/crtend
Use dlsym on all bsd targets
Check .eh_frame on all bsd targets
Disable test3 on FreeBSD and NetBSD and use test1 instead because dlsym not working (WIP)
Disable dlltest and 113_btdll on NetBSD because text relocations are not allowed
Disable 115_bound_setjmp on NetBSD because longjmp is renamed into __longjmp14
- The compiler should not use these
- However tccrun.c & libtcc1.a files should use these
Also:
- use s1->loaded_dlls for loaded dlls instead of dlopens
- alpine musl: fully supported now and tested
- ./configure ...
--config-backtrace=no : disable backtraces
--config-bcheck=no : disable bcheck
- tests:dlltest: enable by default
- tccrun.c : simplify mmaps
- __builtin_alloca : always use asm-alias (instead of #define)
- tccpe.c : use write32le
Fix all testcases for openbsd except dlltest.
Remember dlopen calls and use them to fix openbsd dlsym problem
Use crtbeginS.o/crtendS.o for DLL for bsd
Do not include -ldl for __NetBSD__
Redirect malloc, realloc, ..., free for bsd
Align stack in tests/asm-c-connect-*.c for x86_64
Remove -B in tests/pp/Makefile (not supported on bsd)
- tcc.h: msvc doesn't grok __func__ (reverts previous commit)
- tccgen.c: fortify tcc against bogus code:
- n[sizeof({3;})]; // statement expression outside of function
- f(){"123"4}; // tokens with values following each other
(also, add "type defaults to int" warning for variables)
- tccpe.c: removed a check that caused BSS symbols not to be
exported. Whatever that check was meant to prevent.
- win32/build-tcc.bat: cmd.exe sometimes doesn't grok '-' in labels
- Revert "libtcc: no need to undef"
This reverts commit 2b7aa2a1e1.
- Revert "tcc.h libtcc.c: remove unused defines"
This reverts commit 985d963745.
The point of these "unused defines" is to be unused, that is
to remind people not to use malloc but please to "use_tcc_malloc",
instead.
pretty sure that functions with use_* do not exist
and attempts to use the macros will fail to link
I could rename them to be more up to date like tcc_malloc,
but to me overloading the std calls with macros is
probably taking away control from the programmer,
so for the best is to just get rid of them.
