            Bug ID: 18744
           Summary: FAIL: elf/tst-ld-sse-use when using -march=native in
                    CFLAGS
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: markus at trippelsdorf dot de
                CC: carlos at redhat dot com
  Target Milestone: ---

With:
CFLAGS="-march=native -g -O2 -pipe" CXXFLAGS="-march=native -g -O2 -pipe"
../glibc/configure --prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib
--with-headers=/usr/include --enable-add-ons --enable-kernel=4.0 --with-tls
--with-__thread --enable-bind-now --without-gd --without-cvs --disable-profile
--disable-multi-arch --disable-werror

I get:
