[PATCH] CSKY： About PC relative diff relocation

[Lifang Xia]

Hi everyone,

Here is a patch about PC relative diff relocation in CSKY.

bfd:
            * elf32-csky.c (csky_elf_howto_table): Fill special_function of
            R_CKCORE_PCREL32.
            (csky_elf_relocate_section): Add R_CKCORE_PCREL32 process.
gas:
            * config/tc-csky.c (md_apply_fix): Transmit
            BFD_RELOC_32_PCREL to BFD_RELOC_CKCORE_PCREL32.
            (tc_gen_reloc): Trasmit BFD_RELOC_CKCORE_ADDR32 to
            BFD_RELOC_CKCORE_PCREL32 while pc-relative.
            * config/tc-csky.h (DIFF_EXPR_OK): Define to enable PC relative
            diff relocs.

Can anyone review and commit it?


Thanks.

Lifang.

Hi everyone,

I have already requested a account to access bintuils-gdb, what should I
do next if I want to push this patch?
Can I push it to the master directly by "git push"?

Thanks.
