loadstring - 0x01 loads a string from the storage in the accumulator
store - 0x02 stores the accumulator in a cell
mov - 0x03 moves the value of one to another cell
add - 0x04 adds sth. to the accumulator
sub - 0x05 substracts
mul - 0x06 multiplication (repeats strings)
div - 0x07 division
not - 0x08 binary not

crappy-compiler's Issues

add floating point ops

Separate constant (aka hardcoded) values and instructions.

This will optimize the runtime. Also this can be used to fix the size one instruction takes in the executable and it makes gotos in static instruction set easier to implement.
