I made a few minor fixups (using G_UNMERGE_VALUES instead of creating shift/trunc to extract the two halves, and zexting an inverted compare instead of select_cc). This also does not include the fast math expansion the DAG which converts to f32 and then to f16. I think that belongs in a pre-legalize combine instead.	2020-02-14 10:46:58 -08:00
