From: "jakub at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/41305] New: ICE with -O3 -floop-interchange Date: Tue, 08 Sep 2009 09:16:00 -0000 [thread overview] Message-ID: <bug-41305-87@http.gcc.gnu.org/bugzilla/> (raw) [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #1: Type: text/plain, Size: 1079 bytes --] The following testcase ICEs on x86_64-linux on branches/gcc-4_4-branch with -O3 -floop-interchange: Unable to coalesce ssa_names 99 and 106 which are marked as MUST COALESCE. xi$data_$size__99(ab) and xi$data_$size__106(ab) /tmp/rh520785.ii: In function âvoid foo(int)â: /tmp/rh520785.ii:321: internal compiler error: SSA corruption Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Couldn't reproduce this on the trunk, but that doesn't mean the bug isn't latent there. Doesn't reproduce without -floop-interchange, so I assume it is graphite which is at fault here. -- Summary: ICE with -O3 -floop-interchange Product: gcc Version: 4.4.2 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41305
