From db959e250077ae6b4fc08f53fb322719582c5de6 Mon Sep 17 00:00:00 2001 From: Martin Jambor Date: Wed, 18 Jan 2023 15:29:54 +0100 Subject: [PATCH] ipa: Release body more carefully when removing nodes (PR 107944) The code removing function bodies when the last call graph clone of a node is removed is too aggressive when there are nodes up the clone_of chain which still need them. Fixed by expanding the check. gcc/ChangeLog: 2023-01-18 Martin Jambor PR ipa/107944 * cgraph.cc (cgraph_node::remove): Check whether nodes up the lcone_of chain also do not need the body. --- gcc/cgraph.cc | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/gcc/cgraph.cc b/gcc/cgraph.cc index 5e60c2b73dba..5f72ace9b57b 100644 --- a/gcc/cgraph.cc +++ b/gcc/cgraph.cc @@ -1893,8 +1893,18 @@ cgraph_node::remove (void) else if (clone_of) { clone_of->clones = next_sibling_clone; - if (!clone_of->analyzed && !clone_of->clones && !clones) - clone_of->release_body (); + if (!clones) + { + bool need_body = false; + for (cgraph_node *n = clone_of; n; n = n->clone_of) + if (n->analyzed || n->clones) + { + need_body = true; + break; + } + if (!need_body) + clone_of->release_body (); + } } if (next_sibling_clone) next_sibling_clone->prev_sibling_clone = prev_sibling_clone; -- 2.47.2
