RISC-V: Use pc-relative relocation for FDE initial location
The symbol address in .eh_frame may be adjusted in _bfd_elf_discard_section_eh_frame, and the content of .eh_frame will be adjusted in _bfd_elf_write_section_eh_frame. Therefore, we cannot insert a relocation whose addend symbol is in .eh_frame. Othrewise, the value may be adjusted twice. bfd/ChangeLog 2017-06-26 Kuan-Lin Chen <rufus@andestech.com> * elfnn-riscv.c (perform_relocation): Support the new R_RISCV_32_PCREL relocation. (riscv_elf_relocate_section): Likewise. * elfxx-riscv.c (howto_table): Likewise. (riscv_reloc_map): Likewise. * bfd-in2.h (BFD_RELOC_RISCV_32_PCREL): New relocation. * libbfd.h: Regenerate. gas/ChangeLog 2017-06-26 Kuan-Lin Chen <rufus@andestech.com> * config/tc-riscv.c (md_apply_fix) [BFD_RELOC_32]: Convert to a R_RISCV_32_PCREL relocation. include/ChangeLog 2017-06-26 Kuan-Lin Chen <rufus@andestech.com> * elf/riscv.h (R_RISCV_32_PCREL): New.
