-# SYNOPSIS
-#
-# AX_EXT
-#
-# DESCRIPTION
-#
-# Find supported SIMD extensions by requesting cpuid. When an SIMD
-# extension is found, the -m"simdextensionname" is added to SIMD_FLAGS if
-# compiler supports it. For example, if "sse2" is available, then "-msse2"
-# is added to SIMD_FLAGS.
-#
-# This macro calls:
-#
-# AC_SUBST(SIMD_FLAGS)
-#
-# And defines:
-#
-# HAVE_MMX / HAVE_SSE / HAVE_SSE2 / HAVE_SSE3 / HAVE_SSSE3 / HAVE_SSE4.1 / HAVE_SSE4.2 / HAVE_AVX

-# AX_GCC_X86_AVX_XGETBV
-#
-# DESCRIPTION
-#
-# On later x86 processors with AVX SIMD support, with gcc or a compiler
-# that has a compatible syntax for inline assembly instructions, run a
-# small program that executes the xgetbv instruction with input OP. This
-# can be used to detect if the OS supports AVX instruction usage.
-#
-# On output, the values of the eax and edx registers are stored as
-# hexadecimal strings as "eax:edx" in the cache variable
-# ax_cv_gcc_x86_avx_xgetbv.
-#
-# If the xgetbv instruction fails (because you are running a
-# cross-compiler, or because you are not using gcc, or because you are on
-# a processor that doesn't have this instruction),
-# ax_cv_gcc_x86_avx_xgetbv_OP is set to the string "unknown".
-#
-# This macro mainly exists to be used in AX_EXT.

-# DESCRIPTION
-#
-# On Pentium and later x86 processors, with gcc or a compiler that has a

-# ax_cv_gcc_x86_cpuid_OP.
-#
-# If the cpuid instruction fails (because you are running a
-# cross-compiler, or because you are not using gcc, or because you are on
-# a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
-# is set to the string "unknown".
