If so, use this method. + * partially DONE - one can always add more, but we have the most important stuff * Implement some basic utilities for us to use (memcpy, printf, etc...) * partailly DONE - svc works; once we implement processes we could also kill them on aborts * develop userspace process supervision (handling of interrupt caused by svc instruction, proper handling of other data abort, undefined instruction, etc.) -- cgit v1.2.3
