Hello,
In GCC testsuite the MVE scalar shift execution tests (mve_scalar_shifts[1-4].c) are failings
because of executing them on target hardware which doesn't support MVE instructions. This patch
restricts those tests to execute only on target hardware that support MVE instructions.
Regression tested on arm-none-eabi and found no regressions.
Ok for GCC-10 branch?
Thanks,
Srinath.
