-Instructions with arguments *must* be followed by a minimum number of register

+Instructions that modify values on registers may be followed by up to 3
+register modifiers (`r[0]`, `r[1]` and `r[2]`). When not enough modifiers are
+present after a given instruction, remaining registers are set to `rax` (table
