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.
for floats (currently only). On x86_64 uses built-in fp
constants (in libtcc1.c) to avoid multiple anonymous
instances.
Also: win32/i386: use __alloca for big struct stack store
- use new function int tok_alloc_const(const char*);
- change alloca86.S to preserve EDX
tccelf.c: fix a warning with 'roinf_use'
