c7a57bf1fa Prepended branch name to githash (tcc -v). WIN32: added githash support.
- E.g. "tcc version 0.9.27 mob:675046b (x86_64 Windows)"
- WIN32: Replaced compiler opt -O1 and -Os with -O2 (only 1% larger executable).

dda95e9b0b WAIT/POST_SEM(): generalize interface (and more)
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

eadcee6501 macos: yet another tbd adjustment
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

48df89e10e stdatomics: tidy & cleanup
- remove any error messages that were just for debugging the
  templates really
- don't use c99 in tcc (array designators etc.)
- remove memory model type (cannot be an own type really)
  and move memory model defines from built-in to stdatomics.h
- apply normal casts to non-pointer atomic_function arguments
- tidy the library support
- add some tests for errors/warnings

Also:
- Makefile: move GIT_HASH stuff from CFLAGS to DEFINES and into
  main section (away from what is included by tests for example)
- tccelf.c/tccgen.c: avoid some warnings with newer GCC

lib/tcov.c:
- can't be cross-compiled (needs stdio.h)
- can be included in libtcc1.a

Reason why bt-xxx.o/bcheck.o are linked separatly is because we
don't want then to linked into exe's and dlls at the same time.

1ed4b6ba1a debug_modes, re-unalign, cleanups
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'

bc6c0c34c1 implement test coverage
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

ea82d0826d tccpp: cleanup target-os defines
moved target_machine defines to the <target>-gen.c files.

Also:
- c2str.c moved into conftest.c
- tccdefs.h ; defined(__TINYC__) && !defined(_LOCORE) removed
  (in tinycc __TINYC__ is always defined and _LO... is never.)
- stddef.h : too many #ifdefs, removed
- tccgen.c:stabs: support win32 long doubles aka doubles.
- win32: math.h/tcc_libm.h: fix pointer mismatch in modfl
- tccpp.c: increment include_stack_ptr after the file was
  actually found otherwise it would print
  "in file included from <itself>: file not found..."

9f6b65230a include/tccdefs.h: moved and use it
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)

e2e62fcb8b replace native platform macros in the compiler
- 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

cf8d9cf072 win64: fix pe_isafunc()
- tccpe.c: commit "tidy support for helper function" created
  STT_NOTYPE symbols and hence relied on ad-hoc detection which
  didn't work for x86_64 (as reported by Christian Jullien)

- tccgen.c: However to be more safe the helper symbols are
  now made STT_FUNC anyway (via new VT_ASM_FUNC).

Also:
- tcc.h: minor reorder
- riscv64-*, arm64-*, tccmacho.c: avoid some gcc format-warnings
  (mingw-gcc complains about "%llx" being "unknown conversion",
  although it does work since Vista or so)

72277967ff some cleanups related to recent commits
- configure/Makefile : cleanup, really use CC_NAME
- tccasm.c : remove C99 construct that MSVC doesn't compile
- arm-gen.c, x86_64-gen.c, riscv64-gen.c, tccmacho.c : ditto
- arm64-gen.c: commit 383acf8eff wrote:
  "Instead of a cast, it would be better to pass the exact type."
  It is true that there are better solutions but it is not
  passing the exact type (I think).
- tcctest.c: revert "fix cast test for clang" 03646ad46f
  this obviously wants to test non-portable conversions
- 114_bound_signal.test: clock_nanosleep is too new for older
  linuxes, just use sleep() instead

4eff2b5f6a macos: more adjustments for OSX systems
* instead of /usr/include use the current SDK path as system
  include directory (/usr/include is empty with current tools)
  (this also removes the need to add these paths in individual
  Makefiles)
* define _DARWIN_C_SOURCE in tcc.h to get the full set of decls
  from system headers (e.g. vsnprintf), similar to _GNU_SOURCE
  (and don't define _ANSI_SOURCE in the main Makefile anymore)
* tests/tests2/Makefile: remove the -w flag, it's added when necessary
  in the rules generating the .expect files

94066765ed macos: First cut at generating Mach-O executables
this does generate a working executable for a very simple
example input, e.g. this:

% cat simple.c
int main(void)
{
  return 0;
}
% ./tcc -B. -c simple.c
% ./tcc -nostdlib -B. simple.o -lc
% ./a.out && echo okay
okay

(the -lc is actually not necessary right now, see below).  This
has many limitations:

* no symbol table, hence no calls to external functions from
  e.g. libc, aka libSystemB
* no proper entry point (should be main, but is hardcoded to first
  real .text address)
* libSystemB is hardcoded, no other libs are supported (but again
  no external calls anyway)
* generated Mach-O executable is in old format: neither LC_DYLD_INFO
  no export tries for symbols are created (no symbol table at all!)
* the __LINKEDIT segment is faked and empty, as dyld doesn't like
  it empty even if no symbols point into it
* same with __DATA, dyld wants a non-empty writable segment which
  we enforce with useless data
* no relocations, hence no function call stubs (lazy or not) are
  generated
* hardcodes some other constants as well

7e901299bf Rework expr_infix
- revert const-folding in gvtst() and put it back into
  expr_landor().  Although it did make sense, one reason
  not to do it is __builtin_constant_p() which may return
  true when it shouldn't because of nocode_wanted, see test.

- tccgen_init() can do init_prec(), also for tcc -E.

- for nostalgic reasons, keep the original expression parser
  functions in the source.

- Makefile: remove stale stuff
