Subject: [PATCH] sh-dsp REPEAT support: opcodes:
* sh-opc.h (sh_nibble_type): Remove DISP_8 and DISP_4.
Split IMM_[48]{,BY[24]} into IMM[01]_[48]{,BY[24]}. Add REPEAT.
(sh_arg_type): Add A_PC.
(sh_table): Update entries using immediates. Add repeat.
* sh-dis.c (print_insn_shx): Remove DISP_8 and DISP_4.
Split IMM_[48]{,BY[24]} into IMM[01]_[48]{,BY[24]}. Add REPEAT.
gas:
* config/tc-sh.c (immediate): Delete.
(sh_operand_info): Add immediate member.
(parse_reg): Use A_PC for pc.
(parse_exp): Add second argument 'op'. All callers changed.
(parse_at): Expect pc to be coded as A_PC.
Use immediate field in *op.
(insert): Add fourth argument 'op'. All callers changed.
(build_relax): Add second argument 'op'. All callers changed.
(insert_loop_bounds): New function.
(build_Mytes): Remove DISP_4.
Split IMM_[48]{,BY[24]} into IMM[01]_[48]{,BY[24]}. Add REPEAT.
(assemble_ppi): Use immediate field in *operand.
(sh_force_relocation): Handle BFD_RELOC_SH_LOOP_{START,END}.
(md_apply_fix): Likewise.
(tc_gen_reloc): Likewise. Check for a pcrel BFD_RELOC_SH_LABEL.
include/coff:
* sh.h (R_SH_LOOP_START, R_SH_LOOP_END): Define.
include/elf:
* sh.h (R_SH_LOOP_START, R_SH_LOOP_END): New RELOC_NUMBERs.
bfd:
* reloc.c (_bfd_relocate_contents): Add BFD_RELOC_SH_LOOP_START and
BFD_RELOC_SH_LOOP_END.
* elf32-sh.c (sh_elf_howto_tab): Change special_func to
sh_elf_ignore_reloc for all entries that sh_elf_reloc used to ignore.
Add entries for R_SH_LOOP_START and R_SH_LOOP_END.
(sh_elf_reloc_loop): New function.
(sh_elf_reloc): No need to test for always-to-be-ignored relocs
any more.
(sh_rel): Add entries for BFD_RELOC_SH_LOOP_{START,END}.
(sh_elf_relocate_section): Handle BFD_RELOC_SH_LOOP_{START,END}.
* bfd-in2.h, libbfd.h: Regenerate.
