FT32B is a new FT32 family member. It has a code compression scheme, which requires the use of linker relaxations. The change is quite large, so submission is in several parts.
Part 2 adds a relaxation pass, which actually implements the code compression scheme.
bfd * archures.c: Add bfd_mach_ft32b.
* cpu-ft32.c: Add arch_info_struct.
* elf32-ft32.c: Add R_FT32_RELAX, SC0, SC1,
DIFF32. (ft32_elf_relocate_section): Add clauses
for R_FT32_SC0, SC1, DIFF32. (ft32_reloc_shortable,
elf32_ft32_is_diff_reloc, elf32_ft32_adjust_diff_reloc_value,
elf32_ft32_adjust_reloc_if_spans_insn,
elf32_ft32_relax_delete_bytes, elf32_ft32_relax_is_branch_target,
ft32_elf_relax_section): New function.
* reloc.c: Add BFD_RELOC_FT32_RELAX, SC0, SC1, DIFF32.
* bfd-in2.h: Regenerate.
* libbfd.h: Regenerate.
gas * config/tc-ft32.c (md_assemble): add relaxation reloc
BFD_RELOC_FT32_RELAX. (md_longopts): Add "norelax" and
"no-relax". (md_apply_fix): Add reloc BFD_RELOC_FT32_DIFF32.
(relaxable_section, ft32_validate_fix_sub, ft32_force_relocation,
ft32_allow_local_subtract): New function.
* config/tc-ft32.h: remove unused MD_PCREL_FROM_SECTION.
* testsuite/gas/ft32/insnsc.s: New test exercising all FT32B
shortcodes.
include * elf/ft32.h: Add R_FT32_RELAX, SC0, SC1, DIFF32.
