From e54e3d9f21e2a0833c44d1638dcb1a137f441fa7 Mon Sep 17 00:00:00 2001 From: bernds Date: Sun, 27 Sep 2009 16:56:57 +0000 Subject: [PATCH] * loop-iv.c (iv_analyze_op): Use function_invariant_p, not CONSTANT_P, to test for GRD_INVARIANT. (simple_rhs_p): Anything that's function_invariant_p is fine. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@152226 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/ChangeLog | 6 ++++++ gcc/loop-iv.c | 4 ++-- 2 files changed, 8 insertions(+), 2 deletions(-) diff --git a/gcc/ChangeLog b/gcc/ChangeLog index eb87556ddaa..7a2cce6a6ea 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,9 @@ +2009-09-27 Bernd Schmidt + + * loop-iv.c (iv_analyze_op): Use function_invariant_p, not CONSTANT_P, + to test for GRD_INVARIANT. + (simple_rhs_p): Anything that's function_invariant_p is fine. + 2009-09-27 Rafael Avila de Espindola * gengtype.c (main): Use plunge_files instead of plugin_output. diff --git a/gcc/loop-iv.c b/gcc/loop-iv.c index 2f8650a82f7..af25d02ed61 100644 --- a/gcc/loop-iv.c +++ b/gcc/loop-iv.c @@ -1120,7 +1120,7 @@ iv_analyze_op (rtx insn, rtx op, struct rtx_iv *iv) print_rtl_single (dump_file, insn); } - if (CONSTANT_P (op)) + if (function_invariant_p (op)) res = GRD_INVARIANT; else if (GET_CODE (op) == SUBREG) { @@ -1329,7 +1329,7 @@ simple_rhs_p (rtx rhs) { rtx op0, op1; - if (CONSTANT_P (rhs) + if (function_invariant_p (rhs) || (REG_P (rhs) && !HARD_REGISTER_P (rhs))) return true; -- 2.11.0
