- generating test.ref with tcc makes little sense.
- combine riscv_asm & conversion tests into only two files.
(too many files are bad ...)
tccgen.c:
- init_putv(): improve long double cross constants
now in separate function including some basic conversions
arm-gen.c:
- switch to using TCC_USING_DOUBLE_FOR_LDOUBLE
now it actually never will see VT_LDOUBLE
lib/lib-arm64.c:
- simplify by using unions
tccpp.c:
- reduce amounts of #ifdef TCC_USING_DOUBLE_FOR_LDOUBLE
originally, this was meant to avoid 'void' values leak
to the gen-xxx.c generators which would otherwise try
to load void from/to registers. Also catch invalid types
such as 'unsigned bool' eariler.
tccgen.c:
- expr_cond()/gexpr(): ignore VT_VOID
- gen_cast(): set float reg with static initializers to make
backends happier with invalid input
- init_putv():
improve static compound literal initializers
Also:
- ignore "missing prototype" and "might return no value"
for old style K&R functions
tcc.c, libtcc.c:
- tcc_set_output_type(): return errors from loading crt1.o
tcc.h/tccpp.c:
- fix horrible longstanding mistake with sizeof SValue.tab.
Must have place for sizeof (long double) rather than the
target's LDOUBLE_SIZE.
tccdefs.h:
- add a fake __[u]int128_t for all platforms
arm-gen.c:
- gen_cvt_ftof() must load to reg always
arm64-gen.c:
- simplify arm64_pcs() a bit
i386/x86_64-gen.c:
- do not assume char is signed (for cross compilation arm->x86)
tccelf/macho linker message:
- instead of
"undefined symbol 'X'"
now say
"unresolved reference to 'X'"
which makes it more clear that it is a _linker_error_.
tccasm.c:
- .align/p2align: use 'nop's in exec sections
tccpe.c:
- fix arm64 unwind codes (to make native set/longjmp() work)
sizeof(RUNTIME_FUNCTION) is 8 on arm64 in the first place
no need to note stack slots if we don't save any registers anyway
arm64-gen.c:
- fix long double reg-move
- fix arm64_hfa() for structs with float arrays
- gfunc_prolog(): setup stackframe eariler (simplifies unwind codes)
- new function gv_addr(RC);
win32/include/setjmp.h:
- provide correct definition for setjmo() (frameoffset = 224)
tccasm.c:
- support ".quad" with symbol & relocation
- support ".size"
- fix ". - symbol" arithmetic
win32/lib/crt1.c and win32/include/stdlib.h:
- do not write to __argc/__argv which reside in msvcrt.dll
(msvcrt.dll on arm64 does not like that, crashes on unload)
tcc.c,libtcc.c:
- new functions tcc_fopen/fclose to avoid different stdio unstances
in tcc.exe & libtcc.dll
tests & github workflow:
- add test-win32.bat to run tests with a tcc compiled by build-tcc.bat
- add msvcrt_start.c for gcc/clang to use the same runtime as tcc
the problem is that newer gcc as well as clang and cl are
linking to newer runtimes (such as UCRT) that have partially
different printf format behavior which makes tcctest fail.
the solution here is to force these compilers to link with
msvcrt.dll just like tcc.
Also, there is no gcc on arm64-win32 currently at all.
Anyway, this approach to running the github CI tests
does not require msys2. But It does rely on gnumake
as well as on some 'sh' shell though which seems to be
installed somewhere (maybe it is the one from git).
- include/stddef.h, tcctest.c
Revert "tests/tcctest.c: include stdint.h"
This reverts commit 8f23997ca7
We don't want tcctest.c to rely on system include files
- libtcc.c:
Revert "libtcc.c: Remove unused defines free and realloc"
To be unused is the point why they do exist
This reverts commit 2f88764100.
- tcc.c:
fix formatting of commit e73529865d
- tccpp.c:
parse_include(): print skipped include files too (with tcc -vv[v] file)
next_nomacro(): faster L"str" parsing
- tccgen.c: fix c2y if declaration:
* accept like GCC: if (int a = 0, b, c = x; c)
* accept as "TCC extension": if (int a = 0, b, c = x)
* "speak tcc" with symbol/function names
- README:
cleanup
despite being defined in tcc's own stddef.h, intended to be included by
libtcc.h, libtcc.h actually included the libc's standard include
tested on musl
- tccgen.c: cleanup switch data etc. after errors (*)
- tccpe.c: faster get_dllexports (*)
- tccpe.c: support -Wl,-e[ntry]=... (*)
- libtcc.c: win32: use ANSI functions (GetModuleFileNameA etc.)
- tccrun.c: be nice to tcc-0.9.26 ("struct/enum already defined")
- tccpp.c: be nice to tcc-0.9.27's va_start/end macros
(*) suggested by Robert Schlicht

See test. We need to use 'ind' from later when the address
field of the instruction is put.
Also: fix crash when the substracted symbol is undefined
Also: assume asm-symbols to be lvalues (except func/array)
- LIBTCCAPI int tcc_set_backtrace_func(void *ud, ...)
accept opaque user data pointer,
- tcc -vv -run... : show section info
- use memalign() to allocate runtime memory
- printline_/dwarf : pass output to parent function
- tccpe.c : fix -nostdlib -run
- --config-backtrace=no : make it work again
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:
- 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 casted type was lost when a delayed bool was finally converted
to a value. See testcase, in the wrong case the '(unsigned int)' cast
was ignored, and hence the division was signed reulting in -1 instead of
the proper 0x7fffffff.
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.
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).
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)
(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

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.
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)
This if for clang (pre)release 15.0.0.
tccrun.c:
- update directory/filename read. clang has extra md5 section
- start with filename 0 instead of 1. clang starts at 0
- change dwarf_read_32/dwarf_read_64 into macros
x86_64-link.c:
- Add support for R_X86_64_DTPOFF64/R_X86_64_TPOFF64. Needed by clang
tests/tcctest.c:
- add prototypes for puts/alloca. clang fails with error
- disable other_constraints_test for clang. clang prints 1 instead of 0
There is no code generation in post_type for vla arrays. This code
generation has to be delayed until gen_function.
- post_type save code in type info.
- gen_function use this code to generate vla code.
- enable testcode for vla arrays.
tccgen.c: debug_modes
- don't waste debug function calls during normal execution.
libtcc.c:
- mem_debug: no C99 features in tcc please, for example
({compound expressions}): do not use.
tccgen.c: struct_layout:
- unaligned access is completely ok for most targets.
- Moreover the patch was triggering single byte mode even
for normal aligned access (as with tcc's SymAttr)
static Sym label: don't do this
arm-gen.c:
- use some #ifdefs to explain some code
tccpp.c:
- cleanup UCN chars
libtcc.c:
- replace openbsd library search
configure:
- cleanup strip fallouts
tccgen.c:
- expr_cond(): remove an exotic optimization that eventually
got fixed to do the contrary by a gv(RC_InT)
- pop_local_syms(): remove some args
- init_putv() : use write##le functions to avoid cross-compiler
unaligned access
- __bt_init(): remove unused param 'mode'
