Dan Gohman 61ffa8e373 Instcombine's ShrinkDemandedConstant may strip bits out of constants, ... obscuring what would otherwise be a low-bits mask. Use ComputeMaskedBits to compute what ShrinkDemandedConstant knew about to reconstruct a low-bits mask value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73540 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-16 19:52:01 +00:00
