# 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.
