- tests/Makefile:
fix commit de54586d5b
This hunk it unrelated to the other changes (which are about MacOSX).
It is not useful and partially wrong. Optional tests are meant to
stay optional, btest would work only for i386
- tcc.h:
fix commit c52d79605a by unknown
The message says it's for MINTW but the patch has obviously
no effect for MINGW (which defines __GNUC__). However the patch
seems useful for MSC which however needs _strto(u)i64 with underscore.
- Makefile:
fix commit 5280293d6b
Do not build tcc.o with -DONE_SOURCE because we finally build tcc
from tcc.o and libtcc.a/so
Other tests still have issues, currently with weak linking.
One of the primary stumbling blocks on OSX is the lack of support for
mach-o binaries. Therefore all tcc usage on OSX has to be limited to elf
binaries, presumably produced by tcc itself.
Therefore I had to enable building of tiny_libmaker for OSX. Then changed
the make to use tcc and tiny_libmaker to compile the tcclib1.
In order to compile the tests, specifically the parts that use weak linking,
I have had to define MACOSX_DEPLOYMENT_TARGET to 10.2, which seems like a
hack, but extensive searching seems to indicate that this is the only way
to make apple gcc allow weak linking. Using any other value, bigger or smaller
breaks weak linking.
Also added _ANSI_SOURCE define required by some OSX headers, and some cosmetic
gitignore changes. I believe these changes should not impact other platforms.
This changeset attempts to fix a few problems when giving using
the high 32bits of a 64bit section offset. There are likely more
issues (or perhaps regressions) lurking in the muck here. In general,
this moves a few data type declarations to use uplong. Also, add
support for 64bit mingw32 building under cygwin. Because native
types are used for 64 bit offsets, this won't fix challenges with
cross compiling from 32bit -> 64bit.
Tested under cygwin, against binary compiled with
-Wl,-Ttext=0xffffff8000000000

to the appropriate CFLAGS. In addition, memory hooks are very different
on OSX, so build of bcheck.c had to be disabled for now.
Change of the CFLAGS does affect builds on other platforms, and this needs
to be tested.
Applied patch found on stackoverflow (link below). I also found some
related changes that looked like logically needed. The stackoverflow
changes addressed only two registers which were breaking a compile.
However reading the code in the same file shows two other register
accesses that, while not breaking the build, should have the same fix.

The test driver was changed by changing 'cp -u' into 'cp' as '-u' is not
supported on mac osx.
I found that osx build required the WITHOUT_LIBTCC define. I suspect the
reason for this is tcc unability to handle mach-o files. In order to
properly address this I had to change 'configure' to propagate target os
name to Makefile.
Current state is that simple tests work, but not the whole 'make test'
suite runs.
To the best of my knowledge, these changes should not impact other
platforms.
- use {B} to substitute tcc_lih_path (instead of \b)
- expand CONFIG_TCC_CRTPREFIX in CONFIG_TCC_LIBPATHS
which fixes duplicate CONFIG_SYSROOT.
- put default CONFIG_SYSROOT ("") into tcc.h
- remove hack from commit db6fcce78f
because $(tccdir)/include is already in sysincludes
- configure: error out for unrecognized options.
- win32/build-tcc.bat: put libtcc into base dir where it will
find lib/include automatically, and build libtcc_test example.
--sysincludepaths=.. specify system include paths, colon separated"
Sets CONFIG_TCC_SYSINCLUDEPATHS
--libpaths=... specify system library paths, colon separated"
Sets CONFIG_TCC_LIBPATHS
--crtprefix=... specify location of crt?.o"
Sets CONFIG_TCC_CRTPREFIX
--elfinterp=... specify elf interpreter"
Sets CONFIG_TCC_ELFINTERP
Also the CONFIG_TCC_XXX were renamed to make them look
more consistent.
Also move the elf_interp definitions to tcc.h.
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)
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.
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.
ARM architecture doesn't have any libtcc1 implementation but tcc load
libtcc1.a in all case. This patch add a conditional preprocessor
instruction to load libtcc1.a only when there is an implementation for
the target architecture.
Summary of what was changed or added so far:
These won't work on Win32
* --disable-static option builds libtcca.so.1.0 and associated simlinks.
This replaces libtcca.a, which is a static library with a dynamic one.
* --with-selinux option uses mmap to enable tcc -run to work with Selinux.
* attempt to build tcc1.def on i386 / x86_64 when --enable-cross is used.
If successful, this gets around the "_start not found" or "_winstart not
found" messages when i386-win32-tcc is run on these systems. I say "if"
because it gave me fits of trouble on my system and not all others have
been tested yet. tcc1.def is not a real .def file by the way, but it works,
so it's kind of a dancing bear at this point. We're not concerned that
it's getting the steps wrong. We're just happy it's not eating us for lunch.
* additional make target for lib/tcc1.def on non-win32 builds
tcc1.def was formerly lib/libtcc1.a but has bee made into its
own Makefile target, tcc1.def
* use mv instead of cp on config.h
this fixes a mistake I made which caused Makefile to rebuild
all targets every time
* make links from libtcc.so.1.0 to libtcc.so.1 and libtcc.so
