spim is a self-contained simulator that will run MIPS32 assembly language programs. It reads and executes assembly language programs written for this processor. spim also provides a simple debugger and minimal set of operating system services. spim does not execute binary (compiled) programs.

The current version of spim is 7.3 (August 2006), which is a minor release that cleans up a number of bugs in 7.2:

• Fix for flex 2.5.33 (internal change broke spim's scanner).

• Exception handler can be a semicolon-separated list of files that will be loaded in order. On Unix, SPIM_EXCEPTION_HANDLER environment variable is consulted before command line arguments.

• Memory corruption caused spim to crash when label was defined twice in succession.

• PCSpim updates register and memory display after a parse error while reading a file.

• Eliminated unnecessary null char between strings in list of strings produced by .asciiz.

• Makefiles (in spim/ and xspim/) now contain clearly defined paths for installing executables, exception handler, and man pages. The man pages are no longer installed by the "make install" command.

• Change psfig to epsfig in spim.tex (does anyone still use this obsolete documentation?).
