* define targetos=Windows when --enable-tcc32-mingw, --enable-cygwin, ...
* use TARGETOS insteed HOST_OS when selecting PROGS
* use "$(tccdir)" insteed $(tccdir) on install (spaces in path)
* install tcc.exe too
* produce bcheck.o when cross-compiling too (lib/Makefile)
* force bcheck.o linking by compiling inside tcc_set_output_type()
a dummy program with local array. Otherwise bcheck.o may be not linked.
* replace %xz format specifier with %p in bcheck (don't supported on
Windows)
* call a __bound_init when __bound_ptr_add, __bound_ptr_indir,
__bound_new_region, __bound_delete_region called.
This is because a __bound_init inside ".init" section is not called
on Windows for unknown reason.
* print on stderr a message when an illegal pointer is returned:
there is no segmentation violation on Windows for a program
compiled with "tcc -b"
* remove "C:" subdir on clean if $HOST_OS = "Linux"
* default CFLAGS="-Wall -g -O0" insteed CFLAGS="-Wall -g -O2"
to speed up compilation and more precise debugging.
Force to use a NATIVE_DEFINES insteed of the DEFINES for the
native tcc. After this change we have on debian/ubuntu

This change don't fix a cross compilers
i386-tcc.exe is a compiler for i386 Linux. A HOST_OS variable in Makefile is
introduced and used to select a native compiler (which one to name as tcc.exe)
* Don't use /usr/local/lib/tcc/libtcc1.a for i386 and x86_64
A $(tccdir)/i386 directory was used to install a libtcc1.a
but only when cross compiling. And no x86_64 directory.
* Build/install i386-tcc/x86_64-tcc and not a tcc

Set CONFIG_MULTIARCHDIR for cross compilers.
Chances a cross-compiler will find a working crt*.o
in /usr/lib are more or less 0.
This commit breaks x86 / x86_64 compilres for linux. A solution for the crt*.o
must be discussed.

- Thanks to Kirill "tcc -b itself" should work now
(was removed in d5f4df09ff)
Also:
- tests/Makefile:
- fix spurious --I from 767410b875
- lookup boundtest.c via VPATH (for out-of-tree build)
- test[123]b?: fail on diff error
- Windows: test3 now works (from e31579b076)
- abitest: a libtcc.a made by gcc is not usable for tcc
on WIndows - using source instead (libtcc.c)
- tccpe:
- avoid gcc warning (x86_64)
- Build libtcc1 for cross-compiler on arm (arm to X cross compilers)
- Install libtcc1 and includes for arm to i386 cross compiler
- Add basic check of cross-compilers (compile ex1.c)
- tccgen: error out for cast to void, as in
void foo(void) { return 1; }
This avoids an assertion failure in x86_64-gen.c, also.
also fix tests2/03_struct.c accordingly
- Error: "memory full" - be more specific
- Makefiles: remove circular dependencies, lookup tcctest.c from VPATH
- tcc.h: cleanup lib, include, crt and libgcc search paths"
avoid duplication or trailing slashes with no CONFIG_MULTIARCHDIR
(as from 9382d6f1a0)
- tcc.h: remove ";{B}" from PE search path

"... I'm not sure this is the right way to fix this problem."
And the answer is: No, please. (copying libtcc1.a for tests instead)
- win32/build_tcc.bat: do not move away a versioned file
I removed the XMM6/7 registers from the register list because they are not used
on Win64 however they are necessary for parameter passing on x86-64. I have now
restored them but not marked them with RC_FLOAT so they will not be used except
for parameter passing.
I expect that Linux-x86 is probably fine. All other architectures
except ARM are definitely broken since I haven't yet implemented
gfunc_sret for these, although replicating the current behaviour
should be straightforward.
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.
Some files installed are not generated so need to be copied from the
source tree rather than the build tree.
I also switched texi2html for makeinfo --html since texi2html is
apparently unmaintained.
GCC_MAJOR may be set even is $CC not realy gcc (but i.e. clang, which (as
of 3.1) requires an addtional CFLAG to accept the non portable (gnuisms all
over the place; try to cimpile tcc with Sun^HOracle, Intel, Pathscale, ...
compiler) code).
- except for CONFIG_SYSROOT and CONFIG_TCCDIR
Strictly neccessary it is only for CONFIG_MULTIARCHDIR
because otherwise if it's in config.h it is impossible to
leave it undefined.
But it is also nicer not to use these definitions for
cross-compilers.
- Also:
lib/Makefile : include ../Makefile for CFLAGS
lib/libtcc1.c : fix an issue compiling tcc with tcc on x64
- add quotes: eval opt=\"$opt\"
- use $source_path/conftest.c for OOT build
- add fn_makelink() for OOT build
- do not check lddir etc. on Windows/MSYS
- formatting
config-print.c
- rename to conftest.c (for consistency)
- change option e to b
- change output from that from "yes" to "no"
- remove inttypes.h dependency
- simpify version output
Makefile:
- improve GCC warning flag checks
tcc.h:
- add back default CONFIG_LDDIR
- add default CONFIG_TCCDIR also (just for fun)
tccpp.c:
- fix Christian's last warning
tccpp.c: In function ‘macro_subst’:
tccpp.c:2803:12: warning: ‘*((void *)&cval+4)’ is used uninitialized
in this function [-Wuninitialized]
That the change fixes the warning doesn't make sense but anyway.
libtcc.c:
- tcc_error/warning: print correct source filename/line for
token :paste: (also inline :asm:)
lddir and multiarch logic still needs fixing.
Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.
Also:
- fix "make tcc_p" (profiling version)
- remove old gcc flags:
-mpreferred-stack-boundary=2 -march=i386 -falign-functions=0
- remove test "hello" for Darwin (cannot compile to file)
