Hi everyone,

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

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

Can anyone review and commit it?


Thanks.
