Hi Sanjiv,

I don't remember what the discussion was about any more.  The link doesn't
contain much.  Anyway, as you may have noticed I changed the definition of
the target hook "ReplaceNodeResults".  Probably the same method, or one
with a similar definition, should be used for custom lowering in the case
of an illegal operand.  Would this solve your problem?

Ciao,

Duncan.
