This replaces -> use instead:
-----------------------------------
- tcc_set_linker -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning -> tcc_set_options(s, "-W...");
- tcc_enable_debug -> tcc_set_options(s, "-g");
parse_args is moved to libtcc.c (now tcc_parse_args).
Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp
tested with -D MEM_DEBUG: 0 bytes left
tests/Makefile:
- print-search-dirs when 'hello' fails
- split off hello-run
win32/include/_mingw.h:
- fix for compatibility with mingw headers
(While our headers in win32 are from mingw-64 and don't have
the problem)
tiny_libmaker:
- don't use "dangerous" mktemp
Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.
Also:
- fix "make tcc_p" (profiling version)
- remove old gcc flags:
-mpreferred-stack-boundary=2 -march=i386 -falign-functions=0
- remove test "hello" for Darwin (cannot compile to file)
With:
tcc -g hello.c
gdb a.out
b main
gdb refused to know "main" because of broken dwarf info.
This partially reverts commit 0d598aca08.
I don't remember what the problem was but it was the wrong way
to fix it.
tests:
- add "hello" to test first basic compilation to file/memory
- add "more" test (tests2 suite)
- remove some tests
tests2:
- move into tests dir
- Convert some files from DOS to unix LF
- remove 2>&1 redirection
win32:
- tccrun.c: modify exception filter to exit correctly (needed for btest)
- tcctest.c: exclude weak_test() (feature does not exist on win32)
Fix initialization of args_size before doing register allocation.
When adding hardfloat calling convention the initialization stopped
being performed when !defined (TCC_ARM_EABI).
Add tcc.c as a prerequesite of the %-tcc$(EXESUF) target and compile $<
instead of tcc.c to make sure tcc.c is search in directories specified
by VPATH.
Favor ARM hardfloat over ARM softfloat calling convention. In
particular, this solve the problem of the raspbian distribution where
the softfloat ld.so pathname (lib/ld-linux.so.3) is actually a symlink
to the hardfloat ld.so pathname (/lib/arm-linux-gnueabihf/ld-2.13.so).
Fix overflow detection for R_ARM_CALL, R_ARM_PC24, R_ARM_JUMP24 and
R_ARM_PLT32 relocations on ARM. 26 bits means 25 bits for positive and
negative offsets !
gcc fails the builtin_frame_address test on ARM so we disable it. As a
consequence, the diff between gcc and tcc's output is unecessarily
bigger. Given the big size of the diff currently, this doesn't make a
big difference but may allow to detect a regression in tcc's
implementation of builtin_frame_address.
Change the linking of the frames on ARM. Instead of having fp points 12
bytes above where the old fp is stored, let fp points where the old fp
is stored. That is, we switch from:
| . |
| . |
| . |
| |
| params | <-- fp
--------
| oldlr |
--------
| oldip |
--------
| oldfp |
--------
to:
| . |
| . |
| . |
| |
| params |
--------
| oldlr |
--------
| oldip |
--------
| oldfp | <-- fp

Indirect functions shall have STT_FUNC type in executable dynsym
section. Indeed, a dlsym call following a lazy resolution would pick the
symbol value from the executable dynsym entry. This would contain the
address of the function wanted by the caller of dlsym instead of the
address of the function that would return that address.
Not wise if stddef.h was already included. This is related to commit
3aa26a794e
Instead hack stddef.h to have identical definition and thus
avoid the issue mentionned there.
This reverts commit 63193d1794.
Had some problems (_STATIC_ASSERT) and was too ugly anyway.
For retry, I'd suggest to implement a general function
static inline void memswap (void *p1, void* p2, size_t n);
and then use that. If you do so, please keep the original code
as comment.
