libtcc.c:
- integrate find_dllref loop into tcc_add_dllref()
tccelf.c:
- make sure a DT_NEEDED tag is put for versions even
when the dll was not previously loaded.

Better avoid global variables, at least in new code.
tccdbg.c hopefully should be logically identical to the
former parts in tccgen/elf.c (s1 tccstate added in some
places)
tccelf.c: dwarf linkage seems special per dwarf rather
than special per target.
/* Use "-g" as alias for "-g1". Use "-g0" to disable debug */
So not using -g is now the alias for -g0 ?!?

The new gcc12 release does not support stabs any more.
This was a good reason to add support for dwarf.
The stabs code still works and is used if configure option --dwarf
is not used.
Tested on x86_64, i386, arm, arm64, riscv64 with dwarf-5.
Some debuggers may not support dwarf-5. Try using older dwarf versions
i that case.
The tccmacho.c code probably need some support for dwarf.
arm-gen.c, arm64-gen.c, i386-gen.c, riscv64-gen.c, x86_64-gen.
- fix get_sym_ref symbol size
arm-link.c, arm64-link.c, i386-link.c, riscv64-link.c, x86_64-link.c
- add R_DATA_32U
libtcc.c:
- parse -gdwarf option
tcc.c:
- add dwarf option
tcc.h:
- add dwarf option and sections
tccelf.c:
- init dwarf sections
- avoid adding sh_addr for dwarf sections
- remove dwarf relocs for output dll
- add dwarf sections for tccrun
tccgen.c:
- add dwarf defines + global data
- add dwarf_* functions
- mix dwarf code with stabs code
- a trick is used to emit function name in .debug_line section so
only this section has to be parsed instead of .debug_info and
.debug_abbrev.
- fix init debug_modes
tccrun.c:
- add dwarf sections in rt_context
- init them in tcc_run
- add new dwarf code rt_printline_dwarf to find file/function
dwarf.h:
- New file
tcc-doc.texi:
- document dwarf
configure:
- add dwarf option
lib/Makefile
- change -gstabs into -gdwarf
lib/bt-exe.c, tests/tests2/Makefile, tests/tests2/126_bound_global:
- Add __bound_init call
- Add new testcase to test it
Some headers and source code change macros and
implementation, when __OPTIMIZE_SIZE__ is defined.
This does not change our generated code.

With this code, we can compile more projects,
who expect gcc or clang as compiler. (-std=gnu11 used in Makefiles)
As a further extension, it would be easy to disable gcc extensions

Currently used only with 'tcc_compile_sem' to protect
tcc_compile(), but can be used with other semaphores
Also fix deadlock when tcc_enter_state() is called
recursively for the same state, for example with
tcc_warning() from #pragma comment(option,"...")
Also:
- libtcc.c: error1(): use cstr_[v]printf()
- tcc.h: set TCC_USING_DOUBLE_FOR_LDOUBLE for macho-arm64
(rather than for macho-X86_64)
- tcc.h: define TCC_TARGET_MACHO on __APPLE__ by default
- tcc.h: cleanup TCCState, move DEFASM token stuff to tcctok.h
- tccgen.c: more static
- Makefile/tcc.c: review githash
- tccpe/tcctools: use read() instead of fgets() in pe_load_def()
(all files opened by tcc for reading are now read via 'int fd')
- configure/win32: don't preset CONFIG_TCCDIR (to allow to override it)
- tcc.c -bench: do not include output/run-time

only one set_flag() function required
* can now turn off specific errors: -Werror -Wno-error=option
* new interface: tcc_warning_c(warn_option)("format", args...);
* new warning: -Wdiscarded-qualifiers (on by default)
* new variable 'warn_all' for conditional warnings with -Wall
see also the tests
configure:
- re-enable apple M1-arm64
- however, with --cpu=x86_64, set -arch in CFLAGS/LDFLAGS too
(assume rosetta)
Makefile:
- re-enable osx cross-test (Please do not disable tests)
tcc.h
- set TCC_IS_NATIVE for TCC_TARGET_MACHO on __APPLE__
- apply TCC_USING_DOUBLE_FOR_LDOUBLE for x86_64-osx
libtcc.c:
- cleanup tcc_add_file_internal()
- new function char *tcc_load_text(int fd); and use it for tbd files
Supports linking using .tbd definitions found in the default installed
command-line tools SDK or Xcode.app SDK. Only for creating executables
(not yet for `tcc -run`).
Add support for some more options to generate dependency fragments.
-M is likes -MD but doesn't compile anything so the command won't fail
when just supplied a file without all the relevant libs.
-MM and -MMD are like their counterparts but skip system libs.
Note the behavior of -MD has changed to include system libs. Use -MMD
for the old behavior. This matches gcc's corresponding flags
libtcc.c: add -Wwrite-strings to -Wall
tccgen.c: ro float-consts, string-consts, ro arrays if base type is
tccpe.c: merge IAT with rodata
tccrun.c: mprotect rodata accordingly. free section data after copy
x86_64.c: do not use got for static data.
tcc -bench: show data.rw/ro
Probably STB_LOCAL should never get to put_got_entry(), and currently
it doesn't seem to happen (See "Hack Alarm" there)
Other files: use more ro-data in tinycc
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
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.
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)
This implements support for FreeBSD on aarch64
This partial implements support on FreeBSD(32). This still needs fixing
i386_gen.c because small structures on this target are passed in registers.
Add aligned 16 to __int128_t for FreeBSD
Support __i386__ on FreeBSD/NetBSD
Fix testcase 115 on FreeBSD/NetBSD
Disable testcase 116 on *BSD* because TLS_FUNC/TLS_VAR not set in bcheck.c
Remove FreeBSD/FreeBSD_kernel code from tccelf.c
Fix crtbegin/crtend
Use dlsym on all bsd targets
Check .eh_frame on all bsd targets
Disable test3 on FreeBSD and NetBSD and use test1 instead because dlsym not working (WIP)
Disable dlltest and 113_btdll on NetBSD because text relocations are not allowed
Disable 115_bound_setjmp on NetBSD because longjmp is renamed into __longjmp14
