From: "jakub at redhat dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/23478] [3.4 regression] Miscompilation due to reloading of a var that is also used in EH pad Date: Fri, 19 Aug 2005 18:54:00 -0000 [thread overview] Message-ID: <20050819185123.7601.qmail@sourceware.org> (raw) In-Reply-To: <20050819110806.23478.jakub@redhat.com> ------- Additional Comments From jakub at redhat dot com 2005-08-19 18:51 ------- It can't be inserted just on abnormal critical edges: gcc_assert (!((e->flags & EDGE_ABNORMAL) && EDGE_CRITICAL_P (e))); So I guess we could insert it on the EH edges if !EDGE_CRITICAL_P and only only avoid caller-saving it if EDGE_CRITICAL_P. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23478
