Date: Sun, 01 Aug 2004 16:09:00 -0000 [thread overview] Message-ID: <20040801160946.13399.qmail@sourceware.org> (raw) In-Reply-To: <20040627065304.16225.debian-gcc@lists.debian.org> ------- Additional Comments From zhangjie at magima dot com dot cn 2004-08-01 16:09 ------- I add the following check in verify_flow_insensitive_alias_info (). It shows that there are some other mark_call_clobbered () call sites, which will fail the check. I'm going to look them closer.
