* 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.

* call a __bound_init when __bound_ptr_add, __bound_ptr_indir,

This is because a __bound_init inside ".init" section is not called
on Windows for unknown reason.

int i = i++ causes a segfault because of missing guard. Looking
recursively at all backend functions called from middle end several more
guard appeared to be missing.

Subject: Disable floating-point test for ARM soft-float
tcc is not yet capable of doing softfloat floating-point operations on
ARM, therefore we disable this test for these platforms. Note that tcc
displays a warning to warn ARM users about this limitation
(debian)

tcc is not yet capable of doing softfloat floating-point operations on
ARM, therefore we disable this test for these platforms. Note that tcc
displays a warning to warn ARM users about this limitation
(debian)
A non declared function leads to a seriuos problems. And while
gcc don't turn this warning on lets tcc do it. This warning
can be turned off by -Wno-implicit-function-declaration option.
And autor must explicitly do this if program must be compiled
with this warning off.
* tccpp.c (parse_number): `shift' should be 1 while parsing binary
floating point number.
* tests/tests2/70_floating_point_literals.c: New test cases for
floating point number parsing.
Clear CFLAGS and LDFLAGS to build the tests, in case the main Makefile
passes some flags that aren't handled by tcc (we are not compiling tcc
here, we are using tcc to compile the tests).
- remove -norunsrc switch
Meaning and usage (-run -norun...???) look sort of screwed. Also
general usefulness is unclear, so it was actually to support exactly
one (not even very interesting) test
This partially reverts e31579b076
This provides a simple implementation of alloca for ARM (and enables
the associated testcase). As tcc for ARM doesn't contain an assembler,
we'll have to resort using gcc for compiling it.
Result of float to unsigned integer conversion is undefined if float is
negative. This commit take the absolute value of the float before doing
the conversion to unsigned integer and add more float to integer
conversion test.
- 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)
negate(x) is subtract(-0,x), not subtract(+0,x), which makes
a difference with signed zeros. Also +x was expressed as x+0,
in order for the integer promotions to happen, but also mangles signed
zeros, so just don't do that with floating types.
- 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
