# This file contains common `MI' targets and definitions and it is included
# at the bottom of each `MD' ${MACHINE}/conf/Makefile.${MACHINE}.
#
# Each target in this file should be protected with `if !target(target)'
# or `if !commands(target)' and each variable should only be conditionally
# assigned `VAR ?= VALUE', so that everything can be overridden.
#
# DEBUG is set to -g if debugging.
# PROF is set to -pg if profiling.
#
# To specify debugging, add the config line: makeoptions DEBUG="-g"
# A better way is to specify -g only for a few files.
#
#	makeoptions DEBUGLIST="uvm* trap if_*"
