🐢 Another virtual machine that sucks

FWM Virtual machine

FWM is a shitty virtual machine that crashes if you try to sum two numbers. Written using c2rust utility so just ignore over 4000 lines of output on cargo clippy.

Concepts

1. Be shitty
2. Be shitty
3. Be shitty

It doesn't supports many things because it made just for fun. I got F for my project but made this!

Hello world

FWM assembler (fwm-as crate and fwmc binary) support strings but fwm not, so...

xor %r0, %r0

# write "hello world" to stack
mov [%r0; 0], 104 # h
mov [%r0; 1], 101 # e
mov [%r0; 2], 108 # l
mov [%r0; 3], 108 # l
mov [%r0; 4], 111 # o
mov [%r0; 5], 32  # space
mov [%r0; 6], 119 # w
mov [%r0; 7], 111 # o
mov [%r0; 8], 114 # r
mov [%r0; 9], 108 # l
mov [%r0; 10], 100 # d

# write the string to stdout
write 0, 11 # write 11 bytes from string that starts in 0th stack byte to stdout

By the way, it faster than python! (idk how)

to-do...

Do cargo b -r and run target/release/rustc. Also try cargo doc --open and read about fwm_base...
