/* This file is used to reduce a number of runtime tests for AVX512F
   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.  */
