This PR defines `reverse` for bitvectors and implements a first subset of theorems (`getLsbD_reverse, getMsbD_reverse, reverse_append, reverse_replicate, reverse_cast, msb_reverse`). We also include some necessary related theorems (`cons_append, cons_append_append, append_assoc, replicate_append_self, replicate_succ'`) and deprecate theorems`replicate_zero_eq` and `replicate_succ_eq`. --------- Co-authored-by: Alex Keizer <alex@keizer.dev> Co-authored-by: Kim Morrison <kim@tqft.net> |
