Chip Davis	6d675ae6a2	Correct carry/borrow bit checks. ... Don't use `addsat()`/`subsat()`; that'll erroneously flag cases where the sum is exactly the maximum integer value, or the difference is exactly 0. Also, correct the condition for the `select()` function; it's basically `mix()` with a boolean factor. (What was I *thinking*?)	2018-11-14 10:13:56 -06:00
