Subject: add overloads for SelectionDAG::getLoad, getStore, getTruncStore that take a
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5c5cb2a1717f8e30b1849d7ec1cf269bc5d66877;p=oota-llvm.git

add overloads for SelectionDAG::getLoad, getStore, getTruncStore that take a
MachinePointerInfo.  Among other virtues, this doesn't silently  truncate the
svoffset to 32-bits.
