mips-simulator

A MIPS simulator written in Rust

Currently it can perform most common instructions.

Usage

Sample final output for input (includes both final data segment memory and register values):

j main
foobar:
addi $t0, $zero, 1
jr $ra

main:
addi $t1, $zero, 2
jal foobar
addi $t2, $zero, 3
lui $s0, 0x1001
sw $t2, ($s0)
lw $t3, ($s0)
