> Subject: [PATCH] i386/testsuite: Correct res_ref2 array size for avx512bw-
> vpmov{,us}wb-2.c
>
> Both of the tests under 128 bit are raising:
>
> warning: writing 16 bytes into a region of size 8 [-Wstringop-overflow=]
>
> when compiling, leading to a test fail. The warning is caused by the incorrect
> array size for res_ref2. The wrong size caused the overflow.
>
> Correct them in this patch to fix the test fail.
>
> Ok for trunk?
