             Bug #: 50150
           Summary: misc vect.exp failures for target arm
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: carrot@google.com
              Host: x86_64-build_pc-linux-gnu
            Target: arm-unknown-linux-gnueabi


When I built an arm compiler and run tests on qemu with following command

make check-gcc RUNTESTFLAGS="--target_board=arm-sim/thumb/arch=armv7-a
vect.exp"

I got

Both gcc 4.7 and 4.6 have these failures. But x86-64 compiler doesn't have
these failures.

So how was this toolchain configured by default ?

That's then an inconsistency in the test infrastructure in the non
--with-fpu=neon --with-float=softfp configuration case.

After adding '--with-fpu=neon' '--with-float=softfp' to my configuration, most
of the failure disappeared, but there are still several
