Subject: Add some convenience methods to IRBuilder for constructing aligned loads
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=4d7aa6dbcedfbee7482b8473a63af5ac065380e8;p=oota-llvm.git

Add some convenience methods to IRBuilder for constructing aligned loads
and stores. These will be used in subsequnet patches to SROA to more
systematically manage the alignment on loads and stores.
