Y86-64 Interpreter

A not very idiomatic interpreter of the y86-64 assembly language described in this textbook.

This particular implementation is based on a class project I did in C.

Usage

y86 'object' files are expected as input, where each line takes the following form:

<ADDRESS>: <BYTE ENCODING> | <READABLE ASM>
    ...

For example, the following y86 asm...

nop
rrmovq %rax, %rbx
xorq %rax, %rax
halt

would produce the following object file:

0x0000: 10                     | nop
0x0001: 2003                   | rrmovq %rax, %rbx
0x0003: 6300                   | xorq %rax, %rax
0x0005: 00                     | halt

There are also examples in yo-files/

Options

-c will stop and print the machine state between every cycle, press Return to advance the machine.

-s has the effect of -c and also stops in between stages of each cycle, press Return to advance.

You can also use an online simulator to produce object code, though not all instructions are supported (breakpoints in particular).
