Add a --multiarch-triplet switch to configure. The switch will allow
files to be search for each default path in path/<triplet> and then
path.
Default paths handled that way:
- CONFIG_TCC_SYSINCLUDE_PATHS
- CONFIG_TCC_LIBPATH
- path to crt*.o
- path to libgcc_s.so.1
Path missing: elf interpreter path (will be handled in another commit)
This allows passing colon separated paths to
tcc_add_library_path
tcc_add_sysinclude_path
tcc_add_include_path
Also there are new configure variables
CONFIG_TCC_LIBPATH
CONFIG_TCC_SYSINCLUDE_PATHS
which define the lib/sysinclude paths all in one and can
be overridden from configure/make
For TCC_TARGET_PE semicolons (;) are used as separators
Also, \b in the path string is replaced by s->tcc_lib_path
(CONFIG_TCCDIR rsp. -B option)
Since no code should be generated outside a function, force expr_cond to
only consider constant expression when outside a function since the
generic code can generate some code.
Basically, with:
typedef __attribute__((aligned(16))) struct _xyz {
...
} xyz, *pxyz;
we want the struct aligned but not the pointer.
FIXME: This patch is a hack, waiting for someone in the knowledge
of correct __attribute__ semantics.
This was already possible using
make NOTALLINONE=1
and is now the default.
To build as previously from one big source, use
make ONE_SOURCE=1
Cross compilers are still build from one source because using
separate objects requires separate build directories one per
platform which currently is not (yet) supported by the makefile.
We could probably use gnu-makeish target variables like
$(I386_CROSS): OUTDIR=build/i386
$(X64_CROSS): OUTDIR=build/x86-64
and so on ...
Also NEED_FLOAT_TYPES for arm-gen is removed. It was about
variables that are referenced from outside (libtcc, tccgen).
We could declare them in tcc.h (as with reg_classes) or have
them twice in arm-gen.c. I chose option 2.
array_test is declared and called with no parameters but defined with
one parameter. Compilation succeed (definition is after the use so the
compiler consider the declaration) as well as link (the function exist
and has the right name) but running the test segfault on i386 platforms.
This patch moves the parameter to local variable. If the intention was
to call it with an array parameter then feel free to fix it again.
which live in msvcrt.dll and need __declspec(import) which
works by now.
Also:
- _mingw.h: conditionally define WIN32_LEAN_AND_MEAN
- malloc.h: don't undef alloca
* Rename tcc_split_path_components
* Move tcc_split_path below memory wrapper section
* Ident tcc_split_path by 4
* Remove prefix and suffix clutter in tcc_split_path
* Don't dereference beyond the end of the search paths string
Add the possibility to search headers in several subdirectories of
/usr/local/include and /usr/include. A possible use case would be for
tcc to search for headers in /usr/local/include/x86_64-linux-gnu,
/usr/local/include, /usr/include/x86_64-linux-gnu and /usr/include in
turn.
By default, tcc search libraries in /lib and /usr/local/lib while crt*.o
files are searched in /usr/lib and ld.so is searched in /lib.
Unfortunetely the path are hardcoded in source code. This patch allow
tcc to look in an other directory and also to look in extra directories.
It's then possible to make tcc search libraries in /lib/x86_64-linux-gnu
and /usr/local/lib/x86_64-linux-gnu while crt*.o files are searched in
/usr/lib/x86_64-linux-gnu and ld.so is searched in
/lib/x86_64-linux-gnu.
Use @BINDIR@ in shebang of examples to put the right path on the target
system. That is, use #!/usr/local/bin/tcc if tcc is installed in /usr/local/bin
and #!/usr/bin/tcc if tcc is installed in /usr/bin/tcc.
* Set CFLAGS entirely in configure if not already set.
* Compile bcheck.c with the same flags as the other source files
* Don't strip binaries by default (GB are cheap now) but provide a
--strip-binaries option in configure script.
* Mention the various ARM improvement
* Make changelog consistent with regards to initial capital letters
* Fix credits for VLA
* Fix entry about asm label (variable are also supported)
