# SYNOPSIS
|
||||
#
|
||||
# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Check whether the given FLAG works with the current language's compiler
|
||||
# or gives an error. (Warnings, however, are ignored)
|
||||
#
|
||||
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
||||
# success/failure.
|
||||
#
|
||||
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
||||
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
||||
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
||||
# force the compiler to issue an error when a bad flag is given.
|
||||
#
|
||||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
||||
#
|
||||
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
||||
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

# Find supported SIMD extensions by requesting cpuid. When an SIMD

# 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.
