- Subject: [patch] h8300.md: Remove an ungly hack for udivmod[sh]i4
Hi,
Attached is a patch to remove an ungly hack for udivmod[sh]i4.
The mask off performed at the beginning of the expander is no longer
needed due to a recent patch to optabs.c.
Tested on h8300 port. Committed.

* config/h8300/h8300.md (udivmodqi4): Do not use an expander.
(udivmodhi4): Likewise.
