GCC mainline for powerpc-linux segfaults compiling 175.vpr with "-O2 -ftree-vectorize -maltivec"; this is 32-bit code generation. The failure starts with this patch from rth on 2005-09-17:
http://gcc.gnu.org/ml/gcc-cvs/2005-09/msg00635.html The failure was hidden for awhile by another bug that caused a build failure for 175.vpr with the same options. The segfault is in operand_equal_p at fold_const.c:2413, with a NULL value for TREE_TYPE (arg0). I'll attach a minimized test case. -- Summary: segfault in operand_equal_p with -ftree-vectorize Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24300
