[PATCH] D26149: [DAGCombiner] Match load by bytes idiom and fold it into a single load

[Artur Pilipenko via Phabricator via llvm-commits]

apilipenko added a comment.

We see load by bytes (with optional bswap) patterns in Java code originating from ByteBuffers from the standard library. This is the main motivator for the change. I don't have any numbers for C/C++ code but I expect it's not uncommon.

As of matching patterns like rotate, we don't see it the the code we are interested about, so it's more like "this is where this code can evolve in the future".
