- 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 $source_path/conftest.c for OOT build
- add fn_makelink() for OOT build
- do not check lddir etc. on Windows/MSYS
- formatting
config-print.c
- rename to conftest.c (for consistency)
- change option e to b
- change output from that from "yes" to "no"
- remove inttypes.h dependency
- simpify version output
Makefile:
- improve GCC warning flag checks
tcc.h:
- add back default CONFIG_LDDIR
- add default CONFIG_TCCDIR also (just for fun)
tccpp.c:
- fix Christian's last warning
tccpp.c: In function ‘macro_subst’:
tccpp.c:2803:12: warning: ‘*((void *)&cval+4)’ is used uninitialized
in this function [-Wuninitialized]
That the change fixes the warning doesn't make sense but anyway.
libtcc.c:
- tcc_error/warning: print correct source filename/line for
token :paste: (also inline :asm:)
lddir and multiarch logic still needs fixing.
Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.
Also:
- fix "make tcc_p" (profiling version)
- remove old gcc flags:
-mpreferred-stack-boundary=2 -march=i386 -falign-functions=0
- remove test "hello" for Darwin (cannot compile to file)
tests:
- add "hello" to test first basic compilation to file/memory
- add "more" test (tests2 suite)
- remove some tests
tests2:
- move into tests dir
- Convert some files from DOS to unix LF
- remove 2>&1 redirection
win32:
- tccrun.c: modify exception filter to exit correctly (needed for btest)
- tcctest.c: exclude weak_test() (feature does not exist on win32)
Add tcc.c as a prerequesite of the %-tcc$(EXESUF) target and compile $<
instead of tcc.c to make sure tcc.c is search in directories specified
by VPATH.
Favor ARM hardfloat over ARM softfloat calling convention. In
particular, this solve the problem of the raspbian distribution where
the softfloat ld.so pathname (lib/ld-linux.so.3) is actually a symlink
to the hardfloat ld.so pathname (/lib/arm-linux-gnueabihf/ld-2.13.so).
This commit revert commit 061b5799cc and
subsequent commits to detect whether -Wno-unused-result is supported or
not by the compiler used to compile tcc. No warning about unused results
is issued in a normal build and thus this switch is only needed if
calling make with extra switches in CFLAGS or CPPFLAGS. It should thus
be added with the extra switches when calling make and not in the
Makefile.
- Creates release tarball from *current* git branch
- Includes tcc-doc.html
- converts important windows files files to CRLF
(requirement for the cmd.exe batch processor, convenience for
reading the txt in notepad)
* configure (fn_dirname): New.
Use it to ensure the creation of proper symlinks to Makefiles.
(config.mak): Define top_builddir and top_srcdir.
(CPPFLAGS): Be sure to find the headers.
* Makefile, lib/Makefile, tests/Makefile, tests2/Makefile: Adjust
to set VPATH properly.
Fix confusion between top_builddir and top_srcdir.
TCC_ARM_EABI should be defined when compiling with hardfloat calling
convention. This commit rework the Makefile to distinguish between
calling convention and multiarch and define TCC_ARM_EABI when hardfloat
calling convention is used. The result is to first guess the calling
convention and then add the multiarch triplet if necessary.
This option does not exist in gcc 4.3 and earlier, and it breaks the build on
systems with older compilers. The makefile has been enhanced to test for the
version and adds it only if a newer compiler is detected.
Source fortification now works correctly : it compiles without warning
except unused result and the resulting tcc is working fine. Hence let's
stop disabling source fortification and hide unused result instead.
