            Bug ID: 58641
           Summary: [4.9 Regression] FAIL: gcc.target/i386/pr49002-2.c
                    scan-assembler vmovapd[\t ]*%ymm[0-9]+,[^,]*

Between revisions 202797 and 202814, the following tests have started to fail:

FAIL: gcc.target/i386/pr49002-2.c scan-assembler vmovapd[\t ]*%ymm[0-9]+,[^,]*

for -m32 and -m64, and

FAIL: gcc.target/i386/avx256-unaligned-store-2.c scan-assembler
vmovdqu.*\\*movv16qi_internal/3

for -m64 (see http://gcc.gnu.org/ml/gcc-regression/2013-09/msg00525.html ).
Since the tests are not failing for non-Core targets (see
http://gcc.gnu.org/ml/gcc-testresults/2013-10/msg00376.html ), I suspect
revision 202813:
