Tim Northover d5561bb1f0 ARM: tell LLVM about zext properties of ldrexb/ldrexh ... Implementing this via ComputeMaskedBits has two advantages: + It actually works. DAGISel doesn't deal with the chains properly in the previous pattern-based solution, so they never trigger. + The information can be used in other DAG combines, as well as the trivial "get rid of truncs". For example if the trunc is in a different basic block. rdar://problem/16227836 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205540 91177308-0d34-0410-b5e6-96231b3b80d8		2014-04-03 15:10:35 +00:00
