Hal Finkel cd9acde7f3 Use AA in LoadCombine ... LoadCombine can be smarter about aborting when a writing instruction is encountered, instead of aborting upon encountering any writing instruction, use an AliasSetTracker, and only abort when encountering some write that might alias with the loads that could potentially be combined. This was originally motivated by comments made (and a test case provided) by David Majnemer in response to PR21448. It turned out that LoadCombine was not responsible for that PR, but LoadCombine should also be improved so that unrelated stores (and @llvm.assume) don't interrupt load combining. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221203 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-03 23:19:16 +00:00
