From 04902d4cb5ca18954cf2c32c4f776e53162a0e8f Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Mon, 6 Jun 2011 19:14:31 +0200 Subject: [PATCH] re PR c++/49264 (Internal compiler error: segmentation fault) PR c++/49264 * gimple-fold.c (fold_stmt_1): Don't try to fold *& on the lhs if stmt folded into nothing. * tree-inline.c (fold_marked_statements): If a builtin at the end of a bb folded into nothing, just update cgraph edges and move to next bb. * cgraph.c (cgraph_update_edges_for_call_stmt_node): Allow new_stmt to be NULL. Don't compute count and frequency if new_call is NULL. * g++.dg/opt/pr49264.C: New test.
