# Makefile for nbench, December 11, 1997, Uwe F. Mayer <mayer@tux.org>
# Updated February 18, 2003
default: nbench

# If you are using gcc-2.7.2.3 or earlier:
# The optimizer of gcc has a bug and in general you should not specify
# -funroll-loops together with -O (or -O2, -O3, etc.)
# This bug is supposed to be fixed with release 2.8 of gcc.
#
# This bug does NOT seem to have an effect on the correct compilation
# of this benchmark suite on my Linux box. However, it leads to
# the dreaded "internal compiler error" message on our alpha
# running DEC Unix 4.0b. The Linux-binary that was used to obtain
# the baseline results was nevertheless compiled with
# CFLAGS = -s -static -Wall -O3 -fomit-frame-pointer -funroll-loops
#
# You should leave -static in the CFLAGS so that your sysinfo can be
# compiled into the executable.
CC = gcc
# generic options for gcc
#CFLAGS = -s -static -Wall -O3
CFLAGS = -Wall -O2
# if your gcc lets you do it, then try this one
#CFLAGS = -s -static -Wall -O3 -fomit-frame-pointer -funroll-loops
# for gcc on an older Pentium type processor you can try the following
#CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall -m486 \
# -fforce-addr -fforce-mem -falign-loops=2 -falign-functions=2 \
# -falign-jumps=2 -funroll-loops
# for a newer gcc on a newer Pentium type processor you can try the following
#CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall -march=i686 \
# -fforce-addr -fforce-mem -falign-loops=2 -falign-functions=2 \
# -falign-jumps=2 -funroll-loops
# for a newer gcc on an Athlon XP type processor you can try the following
#CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall -march=athlon-xp \
# -fforce-addr -fforce-mem -falign-loops=2 -falign-functions=2 \
# -falign-jumps=2 -funroll-loops
# For debugging using gcc
#CFLAGS = -g -O3 -Wall -DDEBUG
