* 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.
