# Makefile include fragment to simplify use of cpuflags in pkgsrc
# abs@netbsd.org - freely distributable, no warrenties, stick no bills.
# Try to optimise based on CPU
# Does not affect Imakefiles, and any package that overrides CFLAGS/CXXFLAGS
# Sets four variables:
#
# CPU_FLAGS The output of cpuflags
# CPU_DIR CPU_FLAGS with spaces stripped (eg: for use in PACKAGES)
# CFLAGS Has CPU_FLAGS appended
# CXXFLAGS Has CPU_FLAGS appended
#
.if ! defined(CPU_FLAGS)
