README FILE FOR SPIM & XSPIM ============================ This directory contains SPIM--an assembly language MIPS R2000/R3000 simulator. SPIM is copyrighted by James R. Larus and distributed under the following conditions: You may make copies of SPIM for your own use and modify those copies. All copies of SPIM must retain my name and copyright notice. You may not sell SPIM or distributed SPIM in conjunction with a commercial product or service without the expressed written consent of James Larus. THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. BUILDING SPIM FOR UNIX SYSTEMS ============================== These instructions explain how to compile and install spim and xspim on a Unix system. It is not necessary to compile spim for PCs, as the web site has precompiled versions. To make SPIM, you must first run the Configure script: % Configure Note: Configure compiles a program with the C compiler (cc). If you want it to use another compiler, set the environment variable CC to its name, e.g.: % setenv CC gcc Next, edit the first few non-comment lines of Imakefile (or Makefile.std, if you use that instead) to set the pathnames for your system: TRAP_DIR -- The full pathname of the directory in which to install the SPIM trap handler. BIN_DIR -- The full pathname of the directory in which spim and xspim should be installed. MAN_DIR -- The full pathname of the directory in which the manual pages for spim and xspim should be installed. In general, the remaining parameters need not be changed. Then type: % xmkmf % make (Note: on RS6000's running AIX, you should edit the Makefile to use the c89 compiler rather than cc.) If you want an X-window version of SPIM, also type: % make xspim If you do not have X-windows or the program xmkmf, edit the makefile in Makefile.std and type: % make -f Makefile.std test % make -f Makefile.std xspim To run spim or xspim, the trap handler code must be installed in the directory specified by the variable TRAP_DIR in the Makefile. If the file trap.handler is not installed, spim and xspim fail with a message before they start running. You can either install this file by hand or by typing % make install which also installs spim, xspim, and the manual pages in the directories that you set (above). To test that spim is correctly built, type % make test and examine the output of the test. (Note: the trap handler must be installed before running the test.) NEW VERSIONS OF SPIM =================== I generally release new version of SPIM before each semester (late August and early January). The new version are available by anonymous ftp from: ftp.cs.wisc.edu in the directory: pub/spim/spim.tar.Z The files in this directory are: BLURB A short description of SPIM. Configure A shell script to configure SPIM. Imakefile Input file for the xmkmf program, which produces Makefile for your system. Makefile.std The descriptor file for make program. Only use this file if you do not have xmkmf (see Imakefile). README This file.

WHAT ABOUT SPIM ON SYSTEM XYZ? ============================== SPIM should run without many changes on many Unix systems. Obviously, I have not tested SPIM on many system, nor can I port SPIM to systems that I don't have. However, I would like to hear about the changes necessary to run SPIM on your favorite system.
