# benchmake
#
# Written by Paul Caskey on 20 Jan 1997.
# Compiles Al Aburto's suite of benchmarks.
# See also benchunpack, benchfrob, and benchrun.
#
# I always run the entire suite of benchmarks with a "standard" set of
# compiler options which I know work well on my system.  Usually this is
# a basic optimization flag like -O plus the required -DUNIX.  Then, if
# I have time, I go in by hand and start tweaking.
#
# This script does the massive make with the standard options.  If you
# have a few different optimization methods, I recommend using benchmake
# plus benchrun to run the entire suite with each set of flags, and save
# each one to a different output file for easy comparison.
#
# A "benchmake clean" is desparately needed, but I'm too lazy to hack
# it, so I just "rm -r bench ; benchunpack ; benchfrob" every time.
#
# Just modify the "flags" line below and goferit.  It'll probably crash.
# I haven't written this to be universally portable.  Sorry if it causes
# you more grief than just doing it all by hand.  Give it a shot.

$flags = "CC=cc -O -DUNIX";
