> gcc -O3 -fira -fno-pic -S ira-ice.i ira-ice.i: In function 'MPV_motion_lowres': ira-ice.i:201: internal compiler error: in save_con_fun_n, at caller-save.c:1389 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Without -fno-pic there's a different ICE, and with a lower -O it compiles. Besides these three ICEs there are several miscompiles of ffmpeg r14025, all of which cause it to crash on startup or enter infinite loops, so I guess I can't benchmark IRA for now. -- Summary: IRA -O3 -fno-pic ICE in save_con_fun_n, at caller- save.c:1389 Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: rtl-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: astrange at ithinksw dot com GCC target triplet: i?86-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36673
