22#
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

46# This function simply returns the desired lib directory. With portage
47# 2.0.51, we now have support for installing libraries to lib32/lib64
48# to accomidate the needs of multilib systems. It's no longer a good idea
49# to assume all libraries will end up in lib. Replace any (sane) instances
50# where lib is named directly with $(get_libdir) if possible.
