Update configure and remove dll=no for Darwin.
Also removed dwarf=$dwarf because this is not a config option.
In tccelf.c only add __PAGEZERO if stabs and executable.
In tccrun.c correct rt_printline_dwarf code for dll.
In tests/Makefile disable dlltest with PIC for Darwin because object
format of .o file is still in elf.
In tccmacho.c add dll support and and rpath support.
Corrected trie code. For some reason symbol 'xx' should be after 'xx1'.
Corrected weak symbol support for old macho code.
Used R_JMP_SLOT instead of R_DATA_PTR in check_relocs.
The test failed because atexit/on_exit code was not correct.
Make it look more like the g_exit_context.
Added a sleep to libtcc_test_mt to allow overlap of threads to
detect this problem.
Update tccrun.c to detect rebase for dwarf debug info.
Enabled testcase 126 on macos.
Add prologue_end/epilogue_begin supoort in tcc.h, tccdbg.c, tccgen.c.
See: https://savannah.nongnu.org/bugs/?58606
and: mpfr-4.1.1/tests/tcmp_ui.c
The code '__builtin_constant_p ((i++, 7))' was not working.
I Fixed it in tccgen.c
I added a testcase in tests/tcctest.c. I also wanted to add a test like
'__builtin_constant_p ((10, 7))' but gcc needs -O1 for that to work.
clang (and now tcc) work as expected.
Fix for external functions as pointers in data section.
See testcase 119 and tccmacho.c in check_relocs.
Make bind/rebase code faster in bind_rebase_import.
- Move reloc check out of loop
- Because relocs are sorted we can do bind/rebase by page.
Change name head into seq in trie code.
Remove unused code in bind_rebase.
The __atomic_test_and_set and __atomic_clear code was correct.
They needed locking.
Replaced to code with assembly code.
The changes are in include/stdatomic.h, lib/stdatomic.c, lib/atomic.S
Enabled tests/tests2/124_atomic_counter.c for apple again.
Also moved lib/fetch_and_add.S code to lib/atomic.S.
Removed lib/fetch_and_add.S
Adjusted lib/Makefile
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).
Make code more compatible with gcc. Change
__atomic_store
__atomic_load
__atomic_exchange
__atomic_compare_exchange
Also add (include/stdatomic.h, lib/stdatomic.c):
atomic_thread_fence
atomic_signal_fence
atomic_is_lock_free
And gcc extensions (tcctok.h, tccgen.c, lib/stdatomic.c):
__atomic_fetch_nand
__atomic_and_fetch
__atomic_sub_fetch
__atomic_or_fetch
__atomic_xor_fetch
__atomic_and_fetch
__atomic_nand_fetch
Add new file lib/atomic.S with assembly code for __atomic_compare_exchange_n
for arm/arm64/riscv. Also update lib/Makefile.
Update testcode in 124_atomic_counter and 125_atomic_misc to test new functions.
Also update tests/tests2/Makefile to run tests on arm/arm64/riscv.
Bad assumption make bad things happen:
long d3;
asm(..."1:\tdec %3\n\t" : ... "=&c" (d3)
Which wants 'dec RDI' but did 'dec EDI' on _WIN64.
Also:
- tcctest.c: enable more asm tests for win64
- configure: show errors if any with 'gcc conftest.c'
- tccgen.c: remove decl0(x, y, z)
- x86_64-link.c:
ignore relocation overflow to undefined (weak) symbols
- 104_inline.test:
test lower 32 bits only
- tccpe.c:
support -Wl,--image-base=... above the 32bit range
The script was expecting gcc-3.2 in a specific directory,
works only, when building tcc in the source directory
and creates >3200 files in /tmp (probably a SSD).
Now gcctestsuite.sh works much better.
* use TESTSUITE_PATH, to tell the script the location, where the actual
gcc.c-torture directory is
* work also, when tcc was build in a separate build directory.
use TCC_SOURCE_PATH, when guessing the tcc source directory does not work
* use RUNTIME_DIR to redirect compiler output
(default: XDG_RUNTIME_DIR, then /tmp)
* skip tests for features not implemented in tcc ( *_builtin_*, _Complex )

(As long as it is in the default install location and was not
moved elsewhere into the library search path manually)
Also:
- libtcc.c:
- error1(): show correct line with "In file included from ..."
- support "tcc -Bxxx -vv"
- tcc_new()/tcc_compile(): Don't create elf sections for tcc -E
- tccdbg.c:
- tcc -E -g : revert 1de025c13a
Let's keep things simple, everybody understands 'do_debug'
and dState is set by tcov too (but no debug sections).
- tccgen.c:
- avoid the extra parameter for gind()
(from c3e3a07ed4)
- vla func params: use skip_or_save_block() and enable
VT_LVAL (see 313855c232)
- cleanup nocode_wanted a bit
- tccelf.c:
- tccelf_end_file(): don't try to translate zero-sym relocs
(seems to happen with asm "jmp 0x1000")
- version_add(): do not make "ld-linux.so" DT_NEEDED
1) recursive types have no storage anymore, so a
static int (*p)[x];
declaration is just fine
2) since somewhen VT_VLA doesn't imply VT_ARRAY anymore, so we
now need to check VLA in at least one place before checking
test_lvalue.
((2) should probably be cleaned up again so that VLA does again imply
ARRAY)
- also simplify parse(_line)_comment() and parse_pp_string()
- fixes a continuation problem in strings (see tcctest.c)
- no differences in performance could be observed

an expression like 'i*0', even though it's value is constant and
can be evaluated at compile time is not an integer constant expression,
and hence no null pointer constant, and therefore the conditional
operator doesn't select the other type.
if a switch is unreachable then so are the case labels.
Unlike normal labels they can't possibly be reached from not-yet
parsed code, so there's no reason to enable codegen again for those.
see testcase. We have to "empty" the macro-stack string on
end_macro, as it may be 'tokstr_buf' which is going to be used
twice in recursive invocations of macro_subst_tok. The uses aren't
overlapping but the first one needs to be properly finalized.
The no-operand vm* instructions can be interpreted as having a
funny modrm byte, but unlike no-operand OPC_MODRM it's also the
r/m field which selects the insn, not (only) the reg field (aka group),
so we need another insn type.
as this is the first opcode TCC supports that has a 0xf3 prefix
and uses integer registers (not SSE ones) this also needs some shuffling
of the prefix code to not generate invalid instructions (the REX prefix
_must_ come directly before the main opcode (including 0f prefix), and
hence needs to come after the 0xf3 prefix). Also disable some mnemonics
in asmtest.S that new GAS doesn't support anymore. The only difference
to GAS (in asmtest.S) is now the 'lock negl' instruction which TCC
emits as 'lock; negl'. That's fine.
they look similar to labels 'foobar : 32' (when foobar is a typedef),
but cannot be handled as such in parse_btype, the context is important
(labels can only happen when called from within 'block', aka decl0 in
VT_LOCAL context). This got broken back in 2019 (1b57560).
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
See commit e588b65390.
Was not "wrong" really, just different. But appears to be outdated.
Now disabled by default (top of tccpp.c: ACCEPT_LF_IN_STRINGS)
Also, in skipped code, just warn.
Also: cleanup "Optimize small structure copying on x86_64"
(commit 3715f1d7ee)
- remove some copy&paste coding (tccgen.c)
- RSI/RDI need to be preserved on windows
- simply don't use under bcheck (this is tinycc)
it.Commit 3715f1d makes the error message of bound check on x86_64
different from other platforms,which breaks the test process.But that
commit exactly works well.
commit ec5d94291 made is to that the nocode_wanted state from
inside a statement expression is retained after it. That is wrong
if the statement expression can't be entered to start with. In the
latter case the state from before the stmt-expr is the one we need.
