6a4f3cf127 rework leading underscores
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

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_...

f2ee6b1759 Fix mistake. Change jb by jbe. tiny c round (INT_MAX = 0x7FFFFFFF) to a DWORD boundary and it becomes 0x80000000. Jle treats as -214783648, but Jbe treats as 214783648. Thanks to Jason Hood for explain me this. 2014-07-10 20:41:51 -04:00

8257829623 Fix problem using alloca function, executable crashed even with a exception handler function, when try to allocate INT_MAX. Patch provided by Jason Hood in private e-mail, when I ask to him for help. He say: Feel free to pass it on to the mailing list. 2014-07-10 00:37:20 -04:00

9bd69bf49f build: remove #include "config.h" from target dependent files
This is to make cross build of libtcc1.a easier.

110a4edc15 drop alloca #define
(Because GNU's alloca.h unconditionally #undef's alloca)

Also, remove gcc specific sections in headers. and
instead change tests such that gcc does not use them.
