# SYNOPSIS

#

# AX_CONFIGURE_ARGS

#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Helper macro for AX_ENABLE_BUILDDIR.
|
||||
#
|
||||
# The traditional way of starting a subdir-configure is running the script
|
||||
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
|
||||
# to rely on eval'ing $ac_configure_args however some old autoconf
|
||||
# versions do not provide that. To ensure maximum portability of autoconf
|
||||
# extension macros this helper can be AC_REQUIRE'd so that
|
||||
# $ac_configure_args will alsways be present.
|
||||
#
|
||||
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
|
||||
# spoiled now and must be replaced by "eval + exit $?".
|
||||
#
|
||||
# Example:
|
||||
#
|
||||
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
|
||||
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
|
||||
# eval $SHELL $ac_configure_args || exit $?
|
||||
# ...])

# SYNOPSIS
|
||||
#
|
||||
# AX_GCC_X86_CPUID(OP)
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# On Pentium and later x86 processors, with gcc or a compiler that has a
|
||||
# compatible syntax for inline assembly instructions, run a small program
|
||||
# that executes the cpuid instruction with input OP. This can be used to
|
||||
# detect the CPU type.
|
||||
#
|
||||
# On output, the values of the eax, ebx, ecx, and edx registers are stored
|
||||
# as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
|
||||
# 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".
|
||||
#
|
||||
# This macro mainly exists to be used in AX_GCC_ARCHFLAG.
