./avm [input_file]

Grammar of the pseudo assembly

S := INSTR [SEP INSTR]* #

INSTR := push VALUE
| pop
| dump
| assert VALUE
| add
| sub
| mul
| div
| mod
| print
| exit

VALUE := int8(N)
| int16(N)
| int32(N)
| float(Z)
| double(Z)

N := [-]?[0..9]+

Z := [-]?[0..9]+.[0..9]+

SEP := '\n'+

Bonus

• Binary operator: and ('&'), or ('|'), xor ('^')
• Drop the stack entirely.
• Sort from smallest to biggest operand.
• Reverse the stack, can be combine to sort to have it both ways.
• Display the instructions parsed.
