Subject: Remove code to adjust the iterator for llvm.readio and llvm.writeio.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=53b54be5fcbc396c95939ad6069f35700d455713;p=oota-llvm.git

Remove code to adjust the iterator for llvm.readio and llvm.writeio.
The iterator is pointing at the next instruction which should not disappear
when doing the load/store replacement.
