Also, current mainline is the same as gcc-4.1.1 I can confirm that the difference without -fomit-frame-pointer is much smaller. In fact, 3.4.6 and 4.1.1 are almost the same without it. -- gcc at pdoerfler dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |gcc at pdoerfler dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21676
