Dan Gohman	56b6885104	When doing the very-late shift-and address-mode optimization, create a new DAG node to represent the new shift to keep the DAG consistent, even though it'll almost always be folded into the address. If a user of the resulting address has multiple uses, the nodes may get revisited by a later MatchAddress call, in which case DAG inconsistencies do matter. This fixes PR2849. llvm-svn: 57465	2008-10-13 20:52:04 +00:00

When doing the very-late shift-and address-mode optimization,

create a new DAG node to represent the new shift to keep the
DAG consistent, even though it'll almost always be folded into
the address.

If a user of the resulting address has multiple uses, the
nodes may get revisited by a later MatchAddress call, in which
case DAG inconsistencies do matter.

This fixes PR2849.
