Use opt -S instead of piping bitcode output through llvm-dis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81257 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-08 22:34:10 +00:00			`; RUN: opt < %s -instcombine -S \| not grep ashr`
Fix a ValueTracking rule: RHS means operand 1, not 0. Add a simple ashr instcombine to help expose this code. And apply the fix to SelectionDAG's copy of this code too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65364 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-24 02:00:40 +00:00
