Dear All,

I am working on Cortex-A15 using latest GCC toolchain.
As we know that VFPv4 and SIMDv2 are the Cortex-A15 CPU Features,
so, compared to VFPv3/ SIMDv1, in VFPv4/SIMDv2 has following
additional instruction support
 * VFMA, VFMS - Fused multiply accumulate, Fused multiply subtract.
 * VFNMA, VFNMS - Fused multiply accumulate with negation, Fused
multiply subtract with negation.

To check whether these instructions are generated or not. I took  the
GCC-4.8  branch (snapshot) from FSF.

I noticed there are following testcases available for  VFMA, VFMS instructions
 * gcc/testsuite/gcc.target/arm/neon-vfma-1.c
 * gcc/testsuite/gcc.target/arm/neon-vfms-1.c

But for the VFNMA, VFNMS  instructions there are no test case
available. So I have created the patch to test these instruction.
Please find the attached patch

I have tested these instruction with GCC and these instructions are generated.
Please review and marge this test support patch in gcc main trunk.

Thank You,
Amol Pise
