Dan Gohman 43873d4f73 Use range metadata instead of introducing selects. ... When GlobalOpt has determined that a GlobalVariable only ever has two values, it would convert the GlobalVariable to a boolean, and introduce SelectInsts at every load, to choose between the two possible values. These SelectInsts introduce overhead and other unpleasantness. This patch makes GlobalOpt just add range metadata to loads from such GlobalVariables instead. This enables the same main optimization (as seen in test/Transforms/GlobalOpt/integer-bool.ll), without introducing selects. The main downside is that it doesn't get the memory savings of shrinking such GlobalVariables, but this is expected to be negligible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204076 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-17 19:57:04 +00:00
