In principle 4.0.0's optimization should be a good thing, but once more register pressure makes the code worse because N is not kept in a register. -- What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed| |1 Last reconfirmed|0000-00-00 00:00:00 |2004-09-27 08:52:03 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17647
