Getting the following testsuite failures on ppc-linux: FAIL: gcc.dg/vect/vect-20.c execution test FAIL: gcc.dg/vect/vect-20.c scan-tree-dump-times vectorized 3 loops 1 FAIL: gcc.dg/vect/vect-22.c execution test
These testcases actually fail even with vectorization disabled - it aborts when checking that the results for the code that operates on the char arrays are correct (arrays ca, cb). Changing these arrays to "signed char" fixes the problem. i.e: 35,46c35,46 < char ca[N]; < char cb[N] = --- > signed char ca[N]; > signed char cb[N] = will submit a patch along these lines shortly. -- Summary: execution failure in vect-[20,22].c on ppc-linux Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: regression AssignedTo: dorit at il dot ibm dot com ReportedBy: dorit at il dot ibm dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: powerpc-suse-linux GCC host triplet: powerpc-suse-linux GCC target triplet: powerpc-suse-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18172
