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'
libtcc.c:
Fix unaligned load/store from magic3
tccgen.c:
For packed struct allways use single byte code
If field does not start at at align check it
Align stack correctly with vla
I have implemented the -ftest-coverage option. It works a bit different
from the gcc version. It output .tcov text file which looks almost the
same as a gcov file after a executable/so file is run.
Add lib/tcov.c file
Modify Makefiles to compile/install it
Add -ftest-coverage option in tcc.c/tcc.h/tcc-doc.texi
Add code to tccelf.c/tccgen.c/tccpe.c
Add gen_increment_tcov to tcc.h/*gen.c
unrelated changes:
Add sigemptyset in tccrun.c
Fix riscv64-gen.c tok_alloc label size
As the standard requires, take 4 hex digits after the \u opener of a
Universal Character Name, or take 8 hex digits after \U, but reject
smaller counts and don't consume more (https://port70.net/~nsz/c/c11/n1570.html#6.4.3,
https://port70.net/~nsz/c/c99/n1256.html#6.4.3).
The unicode codepoint used to get truncated to 1 byte. Now it gets expanded into UTF-8,
matching gcc & clang behavior on Linux.
TODO: Universal character names should also be supported in identifiers,
as in, e.g., char \u010dau_sv\u011bte[]="čau_světe";
Disable warning softfloat. OpenBSD works fine.
save/restore s0-s15 during memcpy call for structs
update configure script. Works now on raspberry pi/All BSD
Add eabi_mem.. functions in armeabi.c for OpenBSD
Fix fp register in tccrun.c for OpenBSD
Support OpenBSD/FreeBSD/NetBSD on asm.
move PAGESIZE to tcc.h and use _SC_PAGESIZE (netbsd/arm has 8192 pagesize)
arm:
- fix cmp instruction for qemu (raspberry pi works without patch?)
- increase start address/size
- use large plt size
- add return R_ARM_PREL31
- add R_ARM_TARGET1 to prepare_dynamic_rel
- add gcc_s to FreeBSD (unwind code)
- do not use __clear_cache on bsd (sometimes bad system call)
- do stack unwinding on bsd
- test/tcctest.c: use %lld %llu on bsd
The small common parts within elf_output_file() aren't
worth the many #ifdefs. Also, set section sizes and
allocate section names in 2 separate functions.
These gaps are a result of final_sections_reloc. Here some relocs are removed.
The gaps are then filled with 0 in tcc_output_elf. The 0 is intepreted as
R_...NONE reloc. This does work on most targets but on OpenBSD/arm64 this
is illegal.
