From ea99c7a1262ad596b6c1a4f64fbe85eeda3a2e66 Mon Sep 17 00:00:00 2001 From: vmakarov Date: Fri, 26 Apr 2013 18:11:35 +0000 Subject: 2013-04-26 Vladimir Makarov * rtl.h (struct rtx_def): Add comment for field jump. (LRA_SUBREG_P): New macro. * recog.c (register_operand): Check LRA_SUBREG_P. * lra.c (lra): Add note at the end of RTL code. Align non-empty stack frame. * lra-spills.c (lra_spill): Align stack after spilling pseudos. (lra_final_code_change): Skip subreg change for operators. * lra-eliminations.c (eliminate_regs_in_insn): Make return earlier if there are no operand changes. * lra-constraints.c (curr_insn_set): New. (match_reload): Set LRA_SUBREG_P. (emit_spill_move): Ditto. (check_and_process_move): Use curr_insn_set. Process only single set insns. Don't initialize sec_mem_p and change_p. (simplify_operand_subreg): Use LRA_SUBREG_P. (reg_in_class_p): New function. (process_alt_operands): Use it. Use #if HAVE_ATTR_enabled instead of #ifdef. Add code to remove cycling. (process_address): Check EXTRA_CONSTRAINT_STR. Process even if non-null disp. Reload inner instead of disp when base and index are null. Try to put lo_sum into register. (EBB_PROBABILITY_CUTOFF): Redefine probability in percents. (check_and_process_move): Move code for move cost check to simple_move_p. Remove equiv_substitution. (simple_move_p): New function. (curr_insn_transform): Initialize sec_mem_p and change_p. Set up curr_insn_set. Call check_and_process_move only for single set insns. Use the new function. Move call of check_and_process_move after operand equiv substitution and address process. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@198344 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/lra-eliminations.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) (limited to 'gcc/lra-eliminations.c') diff --git a/gcc/lra-eliminations.c b/gcc/lra-eliminations.c index 5aa0cb82ba2..24a0dc7523d 100644 --- a/gcc/lra-eliminations.c +++ b/gcc/lra-eliminations.c @@ -977,6 +977,9 @@ eliminate_regs_in_insn (rtx insn, bool replace_p) } } + if (! validate_p) + return; + /* Substitute the operands; the new values are in the substed_operand array. */ for (i = 0; i < static_id->n_operands; i++) @@ -984,16 +987,13 @@ eliminate_regs_in_insn (rtx insn, bool replace_p) for (i = 0; i < static_id->n_dups; i++) *id->dup_loc[i] = substed_operand[(int) static_id->dup_num[i]]; - if (validate_p) - { - /* If we had a move insn but now we don't, re-recognize it. - This will cause spurious re-recognition if the old move had a - PARALLEL since the new one still will, but we can't call - single_set without having put new body into the insn and the - re-recognition won't hurt in this rare case. */ - id = lra_update_insn_recog_data (insn); - static_id = id->insn_static_data; - } + /* If we had a move insn but now we don't, re-recognize it. + This will cause spurious re-recognition if the old move had a + PARALLEL since the new one still will, but we can't call + single_set without having put new body into the insn and the + re-recognition won't hurt in this rare case. */ + id = lra_update_insn_recog_data (insn); + static_id = id->insn_static_data; } /* Spill pseudos which are assigned to hard registers in SET.
