I updated the tests/gcctestsuite.sh a bit.
before:
3329 test(s) ok.
210 test(s) skipped.
168 test(s) failed.
28 test(s) exe failed.
after:
3331 test(s) ok.
299 test(s) skipped.
79 test(s) failed.
26 test(s) exe failed.
I found some small problems:
include/tccdefs.h: Add alloca definition for i386 and x86_64
lib/alloca.S/lib/alloca-bt.S: align i386 alloca to 16 bytes.
i386_gen.c vla code and gcc do the same.
x86_64-gen.c: fix typo in comment
Oviously what the patch wants is... on Windows, with
"tcc c:/dir/xyz.dll -run file"... pass the absolute
path of the dll to LoadLibrary() which can make sense
in situations.
Other changes in the patch to other platfurms seem to
have no effect. This reverts 52a9a541b0
except 2 lines in tccpe.c.
Also revert _Float16 patch a06c608625
As long as tcc does not really handle _Float16, we can just define
it in tccdefs.h.
Also move uint128_t to tccdefs.h for same reason.
Update github action (might fix random arm64 crashes)
tccpp.c:
- revert "Preprocessor fix + new testcase"
Fix was not a fix and nobody could understand the test.
This reverts 6379f2ee76
- better fix and add new test (pp/18.c)
tccgen.c:
- remove global variables 'in_sizeof', 'constant_p'
- rework comma expression (gexpr())
- merge func/data 'alias_target' codes
(See 08c777053c)
- move call to do_Static_assert()
- better error: "expression expected before '%s'"
- fix "statement after label"
- remove unnecessary second parameter to block()
- remove unnecessary call to decl()
- revert changes to old C89 test file
See 7f0a28f6ca
tccelf.c:
- rework "...make undefined global symbol STT_NOTYPE"
(See f44060f8fc)
- move tccelf_add_crtbegin() from libtcc.c
tcctest:
- unfix K&R fix (keep old look of K&R functions)
tccrun.c:
- exit(0) returns 0
libtcc.c:
- move #defines for -dumpmachine
- more explicit error "file not found"
(as opposed to error while loading file)
tccpe.c, x86_64-gen.c, i386-asm.c, tccasm.c:
- use R_X86_64_PLT32 for functions on x86_64-win32
tccdefs.h
- empty #defines for _Nonnull, __has_builtin(), etc.
configure:
- Simpler "macOS .dylib ... VERSION letters."
(See 6b967b1285)
Makefile:
- macOS version also
- add cross searchpaths for packages
build.yml:
- disable codesign on macos-11 (doesn't seem to work)
tccgen.c:
- allow cross-compiling 0.0L (cross-compile tcc with tcc)
tccelf.c:
- use alignment of TLS section for PT_TLS
tccpp.c:
- support long double constants on systems that do not support
long doubles (i.e. mark them (VT_DOUBLE | VT_LONG))
tccdefs.h:
#define __has_feature() for android
remove _unaligned (why define a msvc extension under !_WIN32)
These extensions where used by other compiler
to generate different code on old cpu's (arm and x86 before pentium/pentiumpro)
to prevent processor exceptions / very high delays when accessing an unaligned pointer.

tccgen.c:
- just track local_stack for small scopes (can't declare variables)
- fix a vla problem with nested scopes
- move debug N_L/RBRAC into curly braced block
Also:
- tccpp.c: move 'label_...' functions to tccgen.c
- tccpp.c: let get_tok_str() say "<no name>" for anonymous symbols
- tcctest.c: let __pa_symbol() work for memory > 2GB
- 119_random_stuff.c: revert strtoll test (no reason to test libc)
- tccdefs.h/tcctest.c: enable bit fncs for _WIN32
- Makefile:
- use i686-linux-gnu instead of i386-linux-gnu for cross-i386
- update 'make help'
- revert umplicit 'make all' with 'make install' (but print warning)
The apple m1 uses position independent executables (pie).
I have implemented this in tccmacho.c
Apple also uses the stack different for var_args.
Also characters are signed instead of unsigned.
This is implemented in arm64-gen.c/tccdefs.h
Add bounds checking lib to lib/Makefile.
Add underscore support in lib/atomic.S and lib/fetch_and_add.S
Disable __clear_cache in lib/lib-arm64.c (Use system version).
I will try to fix this in future push.
Disable test_asm_call in tests/tcctest.c. Clang does not support @plt.
Also disable weak symbols test.
I will try to fix weak support in future push.
Disable tests/tests2/124_atomic_counter.c for 64BITS.
This is a bug in the atomic code and will be fixed in future push.
You have to use --dwarf configure option. stabs only works with -run.
tested on apple x86_64(10.5) and arm64(12.3).
On an armeabi-v7a device (phone) in the termux app with
clang & make installed this passes all the tests.
Can be used as a cross compiler to create "native apps" as well.
Example 'config-extra.mak' for the cross arm-eabi-tcc:
SYSROOT = <path_to_android_ndk...>/sysroot/usr
TRIPLET = arm-linux-androideabi
ANDRVER = 32
ROOT-arm-eabi = $(SYSROOT)
CRT-arm-eabi = {R}/lib/$(TRIPLET)/$(ANDRVER)
LIB-arm-eabi = {B};{R}/lib/$(TRIPLET)/$(ANDRVER);{R}/lib/$(TRIPLET)
INC-arm-eabi = {B}/lib/include;{R}/include/$(TRIPLET);{R}/include
DEF-arm-eabi = -DTCC_TARGET_ARM -DTCC_ARM_VFP -DTCC_ARM_EABI
DEF-arm-eabi += -DTARGETOS_ANDROID -DCONFIG_TCC_PIE -DCONFIG_NEW_DTAGS
DEF-arm-eabi += -DCONFIG_TCC_ELFINTERP=\"/system/bin/linker\"
# on unix replace ';' by ':'.
$ ./configure && make cross-arm-eabi && make install
- remove any error messages that were just for debugging the
templates really
- don't use c99 in tcc (array designators etc.)
- remove memory model type (cannot be an own type really)
and move memory model defines from built-in to stdatomics.h
- apply normal casts to non-pointer atomic_function arguments
- tidy the library support
- add some tests for errors/warnings
Also:
- Makefile: move GIT_HASH stuff from CFLAGS to DEFINES and into
main section (away from what is included by tests for example)
- tccelf.c/tccgen.c: avoid some warnings with newer GCC
moved target_machine defines to the <target>-gen.c files.
Also:
- c2str.c moved into conftest.c
- tccdefs.h ; defined(__TINYC__) && !defined(_LOCORE) removed
(in tinycc __TINYC__ is always defined and _LO... is never.)
- stddef.h : too many #ifdefs, removed
- tccgen.c:stabs: support win32 long doubles aka doubles.
- win32: math.h/tcc_libm.h: fix pointer mismatch in modfl
- tccpp.c: increment include_stack_ptr after the file was
actually found otherwise it would print
"in file included from <itself>: file not found..."
tcc_define_symbol(): now only for -D on command line
include/tccdefs.h: converted to strings and compiled into
the tcc executable. Can be disabled with
./configure --config-predefs=no
In this case include/tccdefs.h is loaded at runtime. This is
default for other build-methods (build-tcc.bat) also (to avoid
some complexity).
Also:
- lib/Makefile: fix typo
- tcc.h : avoid _strto(u)i64 (for TCC on WIN98/2K)
- tccpp.h:cstr_printf() : workaround incompatible vsnprintf's
(generally faster too)
