faa9744f5d Win: crt, initialize global __argc, __targv and _tenviron of msvcrt
_tenviron: as far as possible, not in ASC '-run' mode.
__argc and __targv are shortcuts for _tWinMain, when you want to use program parameters.

4b3c6e74ab tccgen: nodata_wanted fix, default ONE_SOURCE, etc...
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_...

5f33d313c8 tcc: re-enable correct option -r support
Forgot about it.  It allows to compile several
sources (and other .o's) to one single .o file;

    tcc -r -o all.o f1.c f2.c f3.S o4.o ...

Also:
- option -fold-struct-init-code removed, no effect anymore
- (tcc_)set_environment() moved to tcc.c
- win32/lib/(win)crt1 minor fix & add dependency
- debug line output for asm (tcc -c -g xxx.S) enabled
- configure/Makefiles: x86-64 -> x86_64 changes
- README: cleanup

096125d963 win32: adjust new unicode support
- lib/Makefile: add (win)crt1_w.o

- crt1.c/_runtmain: return to tcc & only use for UNICODE
  (because it might be not 100% reliable with for example
  wildcards (tcc *.c -run ...)

- tccrun.c/tccpe.c: load -run startup_code only if called
  from tcc_run(). Otherwise main may not be defined.  See
  libtcc_test.c

- tests2/Makefile: pass extra options in FLAGS to allow
  overriding TCC

Also:
- tccpe.c: support weak attribute.  (I first tried to solve
  the problem above by using it but then didn't)

86e3cd0c5a Add support for Unicode entries 'wmain' and 'wWinMain' on Windows
'-run' suported. argvs are converted.
But don't use compliled Unicode CLI exe-file to get inputs interactively in other codepage!
Please add other compliling supports than 'build-tcc.bat' (Who is good at them).

bfd1c08d6c tccrun/win64: cleanup runtime function table
- call RtlDeleteFunctionTable
  (important for multiple compilations)

- the RUNTIME_FUNCTION* is now at the beginning of the
  runtime memory.  Therefor when tcc_relocate is called
  with user memory, this should be done manually before
  it is free'd:
      RtlDeleteFunctionTable(*(void**)user_mem);
      [ free(user_mem); ]

- x86_64-gen.c: expand char/short return values to int

8637c1d0ad Remove misc. files
- from win32/include/winapi: various .h

  The winapi header set cannot be complete no matter what.  So
  lets have just the minimal set necessary to compile the examples.

- remove CMake support (hard to keep up to date)
- some other files

Also, drop useless changes in win32/lib/(win)crt1.c

    Subject: win32: Add missing header files for nginx compilation

    The new ones are hoisted from mingw-w64 as most other headers under

There is a DllMain() declaration in the mingw-runtime-4.0.3.1
and it differs from a tcc one.

13b997668e win32: fix libtcc support
For "tcc -run file.c", I was trying to initialize the FP control
in a function in libtcc1.a (_runmain) before calling main.

Unfortunately that turned out to cause problems with for example
libtcc_test since such usage doesn't necessarily define a 'main'
function.

So for tcc -run we're back to relying on the FP control word
that is set in the startup code of tcc.exe rsp. libtcc.dll.

This fixes part of commit 73faaea227

73faaea227 i386-gen: preserve fp control word in gen_cvt_ftoi
- 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

df4c0892f3 tccrun: win64: add unwind function table for dynamic code
This works only when tcc.exe is compiled using MSC.  MinGW does
something in the startup code that defeats it.

a3ebdd0aeb tccpe: support leading underscore for symbols
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

50b040ef83 win64: add tiny unwind data for setjmp/longjmp
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.
