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_...

28435ec58c configure: --config-musl/-uClibc switch & misc cleanups
- configure:
  - add --config-uClibc,-musl switch and suggest to use
    it if uClibc/musl is detected
  - make warning options magic clang compatible
  - simplify (use $confvars instead of individual options)
- Revert "Remove some unused-parameter lint"
  7443db0d5f
  rather use -Wno-unused-parameter (or just not -Wextra)
- #ifdef functions that are unused on some targets
- tccgen.c: use PTR_SIZE==8 instead of (X86_64 || ARM64)
- tccpe.c: fix some warnings
- integrate dummy arm-asm better

44abffe33a more minor fixes
* tccgen: re-allow long double constants for x87 cross
  sizeof (long double) may be 12 or 16 depending on host platform
  (i386/x86_64 on unix/windows).
  Except that it's 8 if the host is on windows and not gcc
  was used to compile tcc.

* win64: fix builtin_va_start after VT_REF removal
  See also a8b83ce43a

* tcctest.c: remove outdated limitation for ll-bitfield test
  It always worked, there is no reason why it should not work
  in future.

* libtcc1.c: exclude long double conversion on ARM

* Makefile: remove CFLAGS from link recipes

* lib/Makefile: use target DEFINES as passed from main Makefile

* lib/armflush.c lib/va_list.c: factor out from libtcc1.c

* arm-gen.c: disable "depreciated" warnings for now

7acf9aa862 final adjustments for release
- configure/Makefiles: minor adjustments

- build-tcc.bat: add -static to gcc options
  (avoids libgcc_s*.dll dependency with some mingw versions)

- tccpe.c/tcctools.c: eliminate MAX_PATH
  (not available for cross compilers)

- tccasm.c: use uint64_t/strtoull in unary()
  (unsigned long sometimes is only uint32_t, as always on windows)

- tccgen.c: Revert (f077d16c) "tccgen: gen_cast: cast FLOAT to DOUBLE"
  Was a rather experimental, tentative commit, not really necessary
  and somewhat ugly too.

- cleanup recent osx support:
  - Makefile/libtcc.c: cleanup copy&paste code
  - tccpp.c: restore deleted function

./tcc -B. -I./include -I. -I.. -D_ANSI_SOURCE -run examples/ex1.c

Note: we don't bother parsing Mach-O/Fat images yet. We blindly
dlopen the image.

569255e6c4 cross-compilers: allow individual configuration
since configure supports only native configuration
a file 'cross-tcc.mak' needs to be created manually.
It is included in the Makefile if present.

# ----------------------------------------------------
# Example config-cross.mak:
#
# windows -> i386-linux cross-compiler
# (it expects the linux files in <prefix>/i386-linux)

ROOT-i386 = {B}/i386-linux
CRT-i386 = $(ROOT-i386)/usr/lib
LIB-i386 = $(ROOT-i386)/lib:$(ROOT-i386)/usr/lib
INC-i386 = {B}/lib/include:$(ROOT-i386)/usr/include
DEF-i386 += -D__linux__

# ----------------------------------------------------

Also:
- use libtcc1-<target>.a instead of directories
- add dummy arm assembler
- remove include dependencies from armeabi.c/lib-arm64.c
- tccelf/ld_add_file: add SYSROOT (when defined) to absolute
  filenames coming from ld-scripts

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

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:

  the problem above by using it but then didn't)

Also:

- win64: align(16) MEM_DEBUG user memory
  on win64 the struct jmp_buf in the TCCState structure which we
  allocate by tcc_malloc needs alignment 16 because the msvcrt
  setjmp uses MMX instructions.

- libtcc_test.c: win32/64 need __attribute__((dllimport)) for
  extern data objects

- tcctest.c: exclude stuff that gcc does not compile
  except for relocation_test() the other issues are mostly ASM
  related.  We should probably check GCC versions but I have
  no idea which mingw/gcc versions support what and which don't.

e31579b076 Fixed tests on Windows (including out-of-tree problems)
Modified tcctest.c so that it uses 'double' in place of 'long double'
with MinGW since this is what TCC does, and what Visual C++ does. Added
an option -norunsrc to tcc to allow argv[0] to be set independently of
the compiled source when using tcc -run, which allows tests that rely on
the value of argv[0] to work in out-of-tree builds.

Also added Makefile rules to automatically update out-of-tree build
Makefiles when in-tree Makefiles have changed.

de54586d5b Further changes improving the OSX build. Everything builds. libtest passes.
Other tests still have issues, currently with weak linking.

One of the primary stumbling blocks on OSX is the lack of support for
mach-o binaries. Therefore all tcc usage on OSX has to be limited to elf
binaries, presumably produced by tcc itself.

Therefore I had to enable building of tiny_libmaker for OSX. Then changed
the make to use tcc and tiny_libmaker to compile the tcclib1.

In order to compile the tests, specifically the parts that use weak linking,
I have had to define MACOSX_DEPLOYMENT_TARGET to 10.2, which seems like a
hack, but extensive searching seems to indicate that this is the only way
to make apple gcc allow weak linking. Using any other value, bigger or smaller
breaks weak linking.

Also added _ANSI_SOURCE define required by some OSX headers, and some cosmetic
gitignore changes. I believe these changes should not impact other platforms.

6e13c35334 Attempt to fix 32 bit OSX build. The fix consists of adding -m32 and -m64
to the appropriate CFLAGS. In addition, memory hooks are very different
on OSX, so build of bcheck.c had to be disabled for now.

Change of the CFLAGS does affect builds on other platforms, and this needs
to be tested.
