Hi Sanjiv,<BR>

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