Bill Seurer <seurer at linux dot vnet.ibm.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |seurer at linux dot vnet.ibm.com --- Comment #6 from Bill Seurer <seurer at linux dot vnet.ibm.com> --- Looks like the simd3/4 tests now work with this patch but g++.dg/vect/pr70729.cc now fails: FAIL: g++.dg/vect/pr70729.cc -std=c++98 (test for excess errors) FAIL: g++.dg/vect/pr70729.cc -std=c++11 (test for excess errors) FAIL: g++.dg/vect/pr70729.cc -std=c++14 (test for excess errors) In the log I see /tmp/cc3mxFhd.s: Assembler messages: /tmp/cc3mxFhd.s:29: Error: unrecognized opcode: `xsxexpdp' compiler exited with status 1 and also /home/seurer/gcc/gcc-test/gcc/testsuite/g++.dg/vect/pr70729.cc:7:10: fatal error: xmmintrin.h: No such file or directory compilation terminated. compiler exited with status 1 Maybe some of the options you removed weren't really redundant?
