This test has never worked on this target, where the port lacks vector insns (the target actually has them, but the point is that the open-code variant should work alternatively the test should not try to execute.)
It used to be a compilation failure, for example with "Fri Jul 4 22:17:01 GMT 2003" as PASS: gcc.dg/compat/vector-1 c_compat_main_tst.o compile FAIL: gcc.dg/compat/vector-1 c_compat_x_tst.o compile FAIL: gcc.dg/compat/vector-1 c_compat_y_tst.o compile (rest unresolved) then with "Thu Oct 9 03:06:11 GMT 2003" as PASS: gcc.dg/compat/vector-1 c_compat_x_tst.o compile PASS: gcc.dg/compat/vector-1 c_compat_y_tst.o compile PASS: gcc.dg/compat/vector-1 c_compat_x_tst.o-c_compat_y_tst.o link FAIL: gcc.dg/compat/vector-1 c_compat_x_tst.o-c_compat_y_tst.o execute which is the same as today; with LAST_UPDATED: "Sat Nov 6 19:25:03 GMT 2004" I get: FAIL: gcc.dg/compat/vector-1 c_compat_x_tst.o-c_compat_y_tst.o execute with the message in the .log being: *** EXIT code 4242 (an abort call) -- Summary: mmix-knuth-mmixware testsuite failure: gcc.dg/compat/vector-1 c_compat_x_tst.o-c_compat_y_tst.o execute Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: hp at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: i686-pc-linux-gnu GCC target triplet: mmix-knuth-mmixware http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18332
