#  Modification Log: 7/28/89 cleaned out workload files
#                    4/17/90 added routines for installing from shar mess
#                    7/23/90 added compile for dhrystone version 2.1
#                          (this is not part of Run file. still use old)
#                          removed HZ from everything but dhry.
#                          HZ is read from the environment, if not
#                          there, you must define it in this file
#                    10/30/90 moved new dhrystone into standard set
#                          new pgms (dhry included) run for a specified
#                          time rather than specified number of loops
#                    4/5/91 cleaned out files not needed for
#                          release 3 -- added release 3 files -ben
#                    10/22/97 added compiler options for strict ANSI C
#                          checking for gcc and DEC's cc on
#                          Digital Unix 4.x (kahn@zk3.dec.com)
#                    09/26/07 changes for UnixBench 5.0
#                    09/30/07 adding ubgears, GRAPHIC_TESTS switch
#                    10/14/07 adding large.txt
#                    01/13/11 added support for parallel compilation
#                    01/07/16 [refer to version control commit messages and
#                              cease using two-digit years in date formats]

SHELL = /bin/sh

# GRAPHIC TESTS: Uncomment the definition of "GRAPHIC_TESTS" to enable
# the building of the graphics benchmarks.  This will require the
# X11 libraries on your system. (e.g. libX11-devel mesa-libGL-devel)
#
# Comment the line out to disable these tests.
# GRAPHIC_TESTS = defined

# Set "GL_LIBS" to the libraries needed to link a GL program.
GL_LIBS = -lGL -lXext -lX11


# COMPILER CONFIGURATION: Set "CC" to the name of the compiler to use
# to build the binary benchmarks.  You should also set "$cCompiler" in the
# Run script to the name of the compiler you want to test.
CC=gcc

# OPTIMISATION SETTINGS:

## Very generic
#OPTON = -O

## For Linux 486/Pentium, GCC 2.7.x and 2.8.x
#OPTON = -O2 -fomit-frame-pointer -fforce-addr -fforce-mem -ffast-math \
#	-m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2

## For Linux, GCC previous to 2.7.0
#OPTON = -O2 -fomit-frame-pointer -fforce-addr -fforce-mem -ffast-math -m486

#OPTON = -O2 -fomit-frame-pointer -fforce-addr -fforce-mem -ffast-math \
#	-m386 -malign-loops=1 -malign-jumps=1 -malign-functions=1

## For Solaris 2, or general-purpose GCC 2.7.x
#OPTON = -O2 -fomit-frame-pointer -fforce-addr -ffast-math -Wall

## For Digital Unix v4.x, with DEC cc v5.x
#OPTON = -O4
#CFLAGS = -DTIME -std1 -verbose -w0

## gcc optimization flags
## (-ffast-math) disables strict IEEE or ISO rules/specifications for math funcs
OPTON = -O3 -ffast-math

## OS detection.  Comment out if gmake syntax not supported by other 'make'.
