-# 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

-# SYNOPSIS
-#
-#   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.
