In brief: Mu is a memory-safe statement-oriented language where most +statements translate to a single instruction of machine code. Blocks consist of +flat lists of instructions.

Variables can be literals ('n'), or live in a register ('var/reg') or in memory ('var') at some 'stack-offset' from the 'ebp' register. Outputs must be registers. To modify a variable in memory, pass it in by reference as an input. (Inputs are more precisely called 'inouts'.) |
