Chandler Carruth d6a41eacf0 Address one of the original FIXMEs for the new SROA pass by implementing ... integer promotion analogous to vector promotion. When there is an integer alloca being accessed both as its integer type and as a narrower integer type, promote the narrower access to "insert" and "extract" the smaller integer from the larger one, and make the integer alloca a candidate for promotion. In the new formulation, we don't care about target legal integer or use thresholds to control things. Instead, we only perform this promotion to an integer type which the frontend has already emitted a load or store for. This bounds the scope and prevents optimization passes from coalescing larger and larger entities into a single integer. llvm-svn: 164479		2012-09-24 00:34:20 +00:00
