tccgen: nodata_wanted fix, default ONE_SOURCE, etc...

2017-07-23T19:24:11+00:00

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_...

fixes & cleanups

2017-02-13T17:23:43+00:00

- tccgen.c/tcc.h: allow function declaration after use:
      int f() { return g(); }
      int g() { return 1; }
  may be a warning but not an error
  see also 76cb1144ef91924c53c57ea71e6f67ce73ce1cc6

- tccgen.c: redundant code related to inline functions removed
  (functions used anywhere have sym->c set automatically)

- tccgen.c: make 32bit llop non-equal test portable
  (probably not on C67)

- dynarray_add: change prototype to possibly avoid aliasing
  problems or at least warnings

- lib/alloca*.S: ".section .note.GNU-stack,"",%progbits" removed
  (has no effect)

- tccpe: set SizeOfCode field (for correct upx decompression)

- libtcc.c: fixed alternative -run invocation
      tcc "-run -lxxx ..." file.c
  (meant to load the library after file).
  Also supported now:
      tcc files ... options ... -run @ arguments ...

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.

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.

lib/alloca*: mark ELF stack access flags as nonexecutable

build: remove #include "config.h" from target dependent files

2010-11-26T19:46:54+00:00

This is to make cross build of libtcc1.a easier.

drop alloca #define

2009-05-16T20:30:13+00:00

(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.

fix makefiles etc for subdirs

2009-04-18T13:08:03+00:00

new subdirs: include, lib, tests
