Re: [RFA:] CGEN sim operation extension fix; frv adjustment needed.


Hi Hans-Peter,

src/cpu:
	* frv.cpu (mabshs): Explicitly sign-extend arguments of abs to DI.
	(DI-ext-HI, DI-ext-UHI, DI-ext-DI): New pmacros.
	(media-arith-sat-semantics): Explicitly sign- or zero-extend
	arguments of "operation" to DI using "mode" and the new pmacros.

Approved - please apply.


Cheers
  Nick
