A basic computer simulator web application using React Bootstrap for the interface.
The computer model has 12 registers and a stack. The zero register always stores zero even though it can be used as a write destination. Despite their names, the bp, sp, and pc registers are no different from the general purpose rN registers.
Most operations can write their result to any register and take their inputs from any combination of registers, the stack, and immediate values. Stack inputs are taken by popping the stack and are populated in order from left to right.
The stack arithmetic operations read their inputs from the stack and push the result back onto the stack. One notable difference between stack arithmetic operations and regular arithmetic operations with stack inputs is that the stack arithmetic operations read their inputs from right to left. As a result, push 5; push 3; ssub will push 5 - 3 onto the stack, but push 5; push 3; sub r1, stack, stack will set r1 to 3 - 5.
