Philip Reames ae1f265bf1 [EarlyCSE] DSE of stores which write back loaded values ... Extend EarlyCSE with an additional style of dead store elimination. If we write back a value just read from that memory location, we can eliminate the store under the assumption that the value hasn't changed. I'm implementing this mostly because I noticed the omission when looking at the code. It seemed strange to have InstCombine have a peephole which was more powerful than EarlyCSE. :) Differential Revision: http://reviews.llvm.org/D15397 llvm-svn: 255739		2015-12-16 01:01:30 +00:00
