gas/config : tc-arm.c
Log message:
* tc-arm.c (struct asm_opcode): Delete comp_suffix and flags. Add
cond_offset. Rename variants->variant.
(insns): Adjust for new format. Explicitly code each variant that
takes flags. Remove temporary instructions.
(struct arm_it): Remove redundant field suffix.
(s_flag, ldr_flags, str_flags, byte_flag, cmp_flags, ldm_flags)
(stm_flags, lfm_flags, sfm_flags, round_flags, fix_flags, except_flag)
(long_flag): Delete.
(struct asm_flg): Delete.
(LONGEST_INST): Delete.
(V4_STR_BIT): Define.
(struct thumb_opcode): Rename variants->variant.
(do_empty): Renamed from do_nop.
(ldst_extend): Delete argument hwse. Split code for half-word and
signed byte instructions to ...
(ldst_extend_v4): ... here.
(ld_mode_required_here): Use ldst_extend_v4.
(do_ldrd): Simplify now that this is only called for ldrd. No
need to test for XScale, which was wrong anyway. Don't reject r12
as a target register. Add test that ldrd doesn't update an index
register.
(do_pld): Don't allow post-indexed or write-back addressing modes.
Adjust call to ldst_extend.
(do_adr): Split code for adrl to ...
(do_adrl): ... here.
(do_cmp): No need to fold in COND_BIT.
(do_ldst): Simplify. Split code for ldrt/strt into do_ldstt. Split
code to handle half-word and signed byte instructions to ...
(do_ldstv4): ... here.
(do_ldstt): New function. Handle load/store with translate.
(do_ldmstm): Write feature modification bits directly into
inst.instruction.
(do_fpa_ldst): Remove suffix handling code.
(do_fpa_dyadic, do_fpa_monadic, do_fpa_from_reg): Likewise.
(do_fpa_ldmstm): Type of access is now held in inst.instruction.
(build_arm_ops_hsh): New function.
(md_begin): Call it. Don't build the ARM opcode directly.
(md_assemble): Simplify ARM instruction handling.
