usage:
tcc -ar [rcsv] lib files...
tcc -impdef lib.dll [-v] [-o lib.def]
also:
- support more files with -c: tcc -c f1.c f2.c ...
- fix a bug which caused tcc f1.c f2.S to produce no asm
- allow tcc -ar @listfile too
- change prototype: _void_ tcc_set_options(...)
- apply -Wl,-whole-archive when a librariy is given
as libxxx.a also (not just for -lxxx)
The problem was with tcctest.c:
unsigned set;
__asm__("btsl %1,%0" : "=m"(set) : "Ir"(20) : "cc");
when with tcc compiled with the HAVE_SELINUX option, run with
tcc -run, it would use large addresses far beyond the 32bits
range when tcc did not use the pc-relative mode for accessing
'set' in global data memory. In fact the assembler did not
know about %rip at all.
Changes:
- memory operands use (%rax) not (%eax)
- conversion from VT_LLOCAL: use type VT_PTR
- support 'k' modifier
- support %rip register
- support X(%rip) pc-relative addresses
The test in tcctest.c is from Michael Matz.
- There's no need to force STRIP_BINARIES on windows since --enable-strip (at
configure) already does exactly that, if one wants to.
- Use the contigured $STRIP instead of the native 'strip', useful when
cross building tcc.
- 'make install-strip' now also strips libtcc.dll on windows (it already does
so now with --enable-strip, and previously it always stripped it).
Summary of current strip options for all platforms:
- configure --enable strip -> 'install -s' for the binaries.
- make install-strip: installs and then configured $STRIP the binaries.
- Otherwise -> no stripping.
Makefile :
- do not 'uninstall' peoples /usr/local/doc entirely
libtcc.c :
- MEM_DEBUG : IDE-friendly output "file:line: ..."
- always ELF for objects
tccgen.c :
- fix memory leak in new switch code
- move static 'in_sizeof' out of function
profiling :
- define 'static' to empty
resolve_sym() :
- replace by dlsym()
win32/64: fix R_XXX_RELATIVE fixme
- was fixed for i386 already in
8e4d64be2f
- do not -Lsystemdir if compiling to .o
Support ./configure && make under msys2 (a new msys fork)
on win32 and win64.
Get rid of CONFIG_WIN64 make-var. (On windows, WIN32 in
general is used for both 32 and 64 bit platforms)
Also:
- cleanup win32/build-tcc.bat
- adjust win32/(doc/)tcc-win32.tx
Except
- that libtcc1.a is now installed in subdirs i386/ etc.
- the support for arm and arm64
- some of the "Darwin" fixes
- tests are mosly unchanged
Also
- removed the "legacy links for cross compilers" (was total mess)
- removed "out-of-tree" build support (was broken anyway)
* Documentation is now in "docs".
* Source code is now in "src".
* Misc. fixes here and there so that everything still works.
I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...
* define targetos=Windows when --enable-tcc32-mingw, --enable-cygwin, ...
* use TARGETOS insteed HOST_OS when selecting PROGS
* use "$(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
* Build/install i386-win-tcc/x86_64-win-tcc and not a i386-win-mingw32-tcc/...
* DEFINES = -DTCC_TARGET_I386... also for i386-tcc and i386-win-tcc
* Make a symlink tcc to the i386-tcc/x86_64-tcc for a "make test"
* Build a $(ARCH) directory with a symlink to the libtcc1.a for a "make test"
* Remove a /usr/local/lib/tcc directory on uninstall
* Remove a /usr/local/share/doc/tcc directory on uninstall
* Remove a $(ARCH) directory on "make clean"
* Remove a *-tcc files on "make clean"
produce a

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.
must be:
# ./x86_64-tcc -vv
