Thanks.
I have another query related to type legalizer.
Can a target ignore certain nodes during legalize? Probably a hook for
target that can be called inside IgnoreNodeResults ()?
We want to keep certain nodes illegal, especially the pointer nodes.
Our target has 16-bit pointer and a few 16-bit insns to perform
arithmetic.
Rest of the stuff is 8-bit so we want to use legalizer to expand them.

while this could be done, I don't like the idea of doing an end-run
around the whole type legalization infrastructure. So you would have
to come up with a pretty convincing argument as to why this can't be
done another way!

[LLVMdev] Type Legalizer Question.
All the sub methods called inside ExpandIntegerOperand like
ExpandInOp_STORE etc have access to the expanded operands map.
Why they aren't passed to target LowerOperation? A target may also want
to use the already expanded Lo and Hi parts.

You don't really need access to the map; just
