From 265459441cc4d0b2123f2266b183e10d97aad639 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Thu, 1 Aug 2013 20:40:24 +0000 Subject: [PATCH] include/opcode/ * mips.h (MIPS16_INSN_WRITE_SP, MIPS16_INSN_READ_31) (MIPS16_INSN_READ_PC, MIPS16_INSN_UNCOND_BRANCH) (MIPS16_INSN_COND_BRANCH): Delete. opcodes/ * mips16-opc.c (UBR, CBR, RD_31, RD_PC): Redefine as INSN2_* flags. (WR_SP): Replace with... (MOD_SP): ...this. (mips16_opcodes): Update accordingly. * mips-dis.c (print_insn_mips16): Likewise. gas/ * config/tc-mips.c (compact_branch_p, uncond_branch_p): Use the same flags for MIPS16 and non-MIPS16 instructions. (gpr_mod_mask): Move the INSN2_MOD_SP case outside the micromips block. (gpr_read_mask): Use INSN2_READ_GPR_31 for MIPS16 instructions too. (gpr_write_mask): Remove MIPS16_INSN_WRITE_SP handling. (can_swap_branch_p, get_append_method): Use the same flags for MIPS16 and non-MIPS16 instructions.
