Class SPIM

java.lang.Object
jminusminus.SPIM
public class SPIM extends Object
This is a Java wrapper class for the SPIM runtime file SPIM.s. Any j-- program that's compiled for the SPIM target must import this class for console IO operations. Note that the functions have no implementations here which means that if the programs using this class are compiled using j--, they will compile fine but won't function as desired when run against the JVM. Such programs must be compiled using the j-- compiler for the SPIM target and must be run against the SPIM simulator.
