Add dwarf support 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
