From 2e1b00367abaf8b6dbb47fd8518d9ac69c326a06 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Wed, 2 Mar 2022 10:48:14 +0100 Subject: [PATCH] cfgrtl: Fix up -g vs. -g0 code generation -flto differences in fixup_reorder_chain [PR104589] This is similar to PR104237 and similarly to that, no testcase included for the testsuite, as we don't have a framework to compile/link with -g -flto and -g0 -flto and compare -fdump-final-insns= results from the lto1 compilations. With -flto, whether two location_t compare equal or not and just express the same location is a lottery. 2022-03-02 Jakub Jelinek PR rtl-optimization/104589 * cfgrtl.cc (fixup_reorder_chain): Use loc_equal instead of direct INSN_LOCATION comparison with goto_locus. --- gcc/cfgrtl.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/cfgrtl.cc b/gcc/cfgrtl.cc index 5675751..74ea14e 100644 --- a/gcc/cfgrtl.cc +++ b/gcc/cfgrtl.cc @@ -4090,7 +4090,7 @@ fixup_reorder_chain (void) && (!NONDEBUG_INSN_P (insn) || !INSN_HAS_LOCATION (insn))) insn = PREV_INSN (insn); if (insn != end - && INSN_LOCATION (insn) == e->goto_locus) + && loc_equal (INSN_LOCATION (insn), e->goto_locus)) continue; if (simplejump_p (BB_END (e->src)) && !INSN_HAS_LOCATION (BB_END (e->src))) @@ -4112,7 +4112,7 @@ fixup_reorder_chain (void) while (insn != end && !NONDEBUG_INSN_P (insn)) insn = NEXT_INSN (insn); if (insn != end && INSN_HAS_LOCATION (insn) - && INSN_LOCATION (insn) == e->goto_locus) + && loc_equal (INSN_LOCATION (insn), e->goto_locus)) continue; } nb = split_edge (e); -- 2.7.4
