ARM disassembler was erroneously accepting an invalid LSL instruction.
For register-controlled shifts, we should check that the encoding constraint Inst{7} = 0 and Inst{4} = 1 is satisfied. rdar://problem/9237693 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128941 91177308-0d34-0410-b5e6-96231b3b80d8
