Benjamin Kramer 2f7228b80c Generalize the and-icmp-select instcombine further by allowing selects of the form ... (x & 2^n) ? 2^m+C : C we can offset both arms by C to get the "(x & 2^n) ? 2^m : 0" form, optimize the select to a shift and apply the offset afterwards. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121609 91177308-0d34-0410-b5e6-96231b3b80d8		2010-12-11 10:49:22 +00:00
