/* This file is used to reduce a number of runtime tests for AVX512F
and AVX512VL instructions. Idea is to create one file per instruction -
avx512f-insn-2.c - using defines from this file instead of intrinsic
name, vector length etc. Then dg-options are set with appropriate
-Dwhatever options in that .c file producing tests for specific
length. */
