Fix sh-elf linker relaxation:
gcc:
* config/sh/sh.h (EXTRA_SPECS): Add subtarget_asm_relax_spec and
subtarget_asm_isa_spec.
(SUBTARGET_ASM_RELAX_SPEC, SUBTARGET_ASM_ISA_SPEC): Define.
(ASM_SPEC): Define as SH_ASM_SPEC.
(SH_ASM_SPEC): New; take the role of ASM_SPEC, but safe from svr4.h.
Use subtarget_asm_relax_spec and subtarget_asm_isa_spec.
* config/sh/elf.h (ASM_SPEC): Use SH_ASM_SPEC.
(SUBTARGET_ASM_ISA_SPEC): Undef / define.
gcc/testsuite:
gcc.dg/sh-relax.c: New test.
include/elf:
* sh.h (EF_SH_MERGE_MACH): Make sure SH2E & SH3/SH3E merge to SH3E,
and SH2E & SH4 merge to SH4, not SH2E.
gas:
* config/tc-sh.c (sh_dsp): Replace with preset_target_arch.
(md_begin): Use preset_target_arch.
(md_longopts): Make isa option unconditional.
(md_parse_option): Make OPTION_DSP and OPTION_ISA sh4 / any
set preset_target_arch.
(md_apply_fix3): If BFD_ASSEMBLER, adjust SWITCH_TABLE fixups
by -S_GET_VALUE (fixP->fx_subsy).
(tc_gen_reloc): For SWITCH_TABLE fixups, the symbol is fixp->fx_subsy,
and the addend is 0.
Adjust addend of R_SH_IND12W relocations by fixp->fx_offset - 4.
* config/tc-sh.h (TC_FORCE_RELOCATION_SUB_LOCAL): Define.
bfd:
elf32-sh.c (sh_elf_howto_tab): Make R_SH_IND12W into an ordinary
relocation (no special function), and make it non-partial_inplace.
(sh_elf_relax_section): When creating a bsr, use a consistent value
no matter if the symbol is extern or not; set addend to -4.
Don't swap load / non-load instructions for SH4.
(sh_elf_relax_delete_bytes): In R_SH_IND12W case, check the offset
rather than if the symbol is external to determine if adjusting the
offset makes sense. Adjust the addend too if appropriate.
(sh_elf_relocate_section): In R_SH_IND12W, don't fiddle with the
relocation.
