Macro Definition Documentation

#define OP_ADD   1

OpCode values. The names are straight from the MIPS manual except for the following special ones:

OP_UNIMP - means that this instruction is legal, but hasn't been implemented in the simulator yet. OP_RES - means that this is a reserved opcode (it isn't supported by the architecture).
