23# ecpu_check array_of_cpu_flags
24#
25# array_of_cpu_flags - An array of cpu flags to check against USE flags
26#
27# Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28# cpu flag that is not supported in their processor flags, it will warn the
29# user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30# obviously using different cpu flags than their own cpu ). Examples:
31#
32# CPU_FLAGS=(mmx mmx2 sse sse2)
33# ecpu_check CPU_FLAGS
