Constants & Variables

clearLoopCutoff const #

clearLoopCutOff is the (somewhat arbitrary) value above which it is better to have a loop of clear instructions (e.g. XCs) rather than just generating multiple instructions (i.e. loop unrolling). Must be between 256 and 4096.

const clearLoopCutoff = 1024

Functions
