From 895fdc1f4c9ff1dfb18b80af838aa353363edb40 Mon Sep 17 00:00:00 2001 From: Iain Buclaw Date: Sun, 1 Nov 2020 16:39:10 +0100 Subject: [PATCH] ipa: Fix segmentation fault in function_summary::get(cgraph_node*) PR 97660 occurs when cgraph_node::get returns NULL, and this NULL cgraph_node is then passed to clone_info::get. As the original assert prior to the regressing change in r11-4587 allowed for the cgraph_node to be NULL, clone_info::get is now only called when cgraph_node::get returns a nonnull value. gcc/ChangeLog: PR ipa/97660 * cgraph.c (cgraph_edge::redirect_call_stmt_to_callee): Don't call clone_info::get when cgraph_node::get returns NULL. --- gcc/cgraph.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/gcc/cgraph.c b/gcc/cgraph.c index 9f3a7284310..36bdb009bf8 100644 --- a/gcc/cgraph.c +++ b/gcc/cgraph.c @@ -1491,9 +1491,11 @@ cgraph_edge::redirect_call_stmt_to_callee (cgraph_edge *e) } if (flag_checking && decl) { - cgraph_node *node = cgraph_node::get (decl); - clone_info *info = clone_info::get (node); - gcc_assert (!node || !info || !info->param_adjustments); + if (cgraph_node *node = cgraph_node::get (decl)) + { + clone_info *info = clone_info::get (node); + gcc_assert (!info || !info->param_adjustments); + } } clone_info *callee_info = clone_info::get (e->callee); -- 2.30.2
