autotools: AX_SSE detects the compiler SSE capabilities
For each SSE feature supported by the compiler * add the corresponding -msse* flag * define HAVE_SSE* Remove AX_EXT because it decides based on the CPU capabilities of the machine compiling the binary which may or may not be the one running them. Signed-off-by: Loic Dachary <loic@dachary.org>

# 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

#

# 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

#
|

# 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".
