6ca228339c arm-asm: Accept additional register names 2025-05-07 22:29:46 +02:00

8c4e67380e arm bits 
arm-asm.c: add forward branches & some ops
lib/armeabi.c: faster i/udivmod (asm)
arm-gen.c: use movw/movt to load constants for CPUVER >= 70
configure: use dwarf-4 debug sections on android, detect idiv
lib/Makefile: always add -I$(TOP) for access to config.h
tcdbg.c: add a "code mapping symbol" to help out llvm-objdump
tccelf.c: don't load SHT_ARM_EXIDX, modify ARM.attributes
tccpp.c: accept '@' for arm asm comments

6b78e561c8 div fixes 
- Makefile: don't produce unknown targets
- libtcc.c: tcc_set_linker(): improve parser
- tcc.h: tcc_internal_error(): don't record __FILE__ (for privacy reasons)
- tccgen.c:
  - reject pointer + float operation
  - use 'int level' for builtin_frame/return_address
  - save_regs(): remove VT_ARRAY (confuses riscv64-gen)
- tccpe.c: store just basename of loaded dlls (rather than full path)
- tccpp.c: remove unused TAL defines
- *-link.c: add missing ST_FUNC
- i386-gen.c: fix thiscall
- riscv64-asm.c/arm-asm.c: stay simple C89
  - avoid .designators, decl after statement
  - avoid multiple instances of same static const objects
  - use skip() instead of next() & expect()
  - use cstr_printf() instead of snprintf() & cstr_cat()
  - tcc_error(), expect(): never return

0703df1a6a Fix Extended Asm ignored constraints 
This commit fixes the case where the register of for the Extended Asm
input or output is known. Before this commit, the following case:

  register long __a0 asm ("a0") = one;
  asm volatile (
       "ecall\n\t"
       : "+r" (__a0) // NOTE the +r here
  );

Didn't treat `a0` as an input+output register (+ contraint) as the code
skipped the constraint processing when the register was already chosen
(instead of allocated later).

This issue comes from f081acbfba, that was
taken as a reference in every other Extended Assembler implementation.

/* Use "-g" as alias for "-g1". Use "-g0" to disable debug */

So not using -g is now the alias for -g0 ?!?

aea68dbb40 arm-asm, arm64-link: Silence warnings for unused functions 
The code needs to be fixed: use the functions or remove them.

arm-asm.c:
asm_parse_vfp_regvar()

arm64-link:
gotplt_entry_type()
create_plt_entry()

72f1dea537 tccelf: use rodata_section, use more rodata in tcc itself 
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
