[RFA:] sim/cgen-ops.h: Add ADDCQI, ADDCFQI, ADDOFQI, SUBCQI, SUBCFQI, SUBOFQI

[Hans-Peter Nilsson]

I thought this was supposed to go to gdb, but I got no reaction
there and I see a recent patch went to cgen & sid, hence
forwarded.

Subject: [RFA:] sim/cgen-ops.h: Add ADDCQI, ADDCFQI, ADDOFQI, SUBCQI, SUBCFQI, SUBOFQI

These functions looked missing.  At least I get undefined
references to these for a CGEN port in progress, and they look
like they *should* be there.  CCNOL (CC me; I'm not on this
list), please.

Ok to commit?

2002-01-28  Hans-Peter Nilsson  <hp@axis.com>

	* cgen-ops.h (ADDCQI, ADDCFQI, ADDOFQI, SUBCQI, SUBCFQI, SUBOFQI):
	New functions.
