From 972ee845f54839e9bd2e4611bb268d75440f3845 Mon Sep 17 00:00:00 2001 From: Eric Botcazou Date: Wed, 20 Oct 2021 10:42:56 +0200 Subject: Fix PR middle-end/102764 This is a regression present on the mainline in the form of -fcompare-debug failure at -O3 on a compiler-generated testcase. Fixed by disregarding a debug statement in the last position of a basic block to reset the current location for the outgoing edges. gcc/ PR middle-end/102764 * cfgexpand.c (expand_gimple_basic_block): Disregard a final debug statement to reset the current location for the outgoing edges. gcc/testsuite/ * gcc.dg/pr102764.c: New test. --- gcc/cfgexpand.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gcc/cfgexpand.c') diff --git a/gcc/cfgexpand.c b/gcc/cfgexpand.c index 03260b0..8b067f9 100644 --- a/gcc/cfgexpand.c +++ b/gcc/cfgexpand.c @@ -6090,7 +6090,7 @@ expand_gimple_basic_block (basic_block bb, bool disable_tail_calls) /* Expand implicit goto and convert goto_locus. */ FOR_EACH_EDGE (e, ei, bb->succs) { - if (e->goto_locus != UNKNOWN_LOCATION || !stmt) + if (e->goto_locus != UNKNOWN_LOCATION || !stmt || is_gimple_debug (stmt)) set_curr_insn_location (e->goto_locus); if ((e->flags & EDGE_FALLTHRU) && e->dest != bb->next_bb) { -- cgit v1.1
