This is a continuation of r167064 ( http://llvm.org/viewvc/llvm-project?view=revision&revision=167064 ). That patch started to fix PR14221 ( http://llvm.org/bugs/show_bug.cgi?id=14221 ), but it was not completed. Differential Revision: http://reviews.llvm.org/D6330 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224624 91177308-0d34-0410-b5e6-96231b3b80d8

; There is a mismatch between the intrinsic and the actual instruction.
|
|
; The actual instruction has a partial update of dest, while the intrinsic
|
|
; passes through the upper FP values. Here, we make sure the source and
|
|
; destination of each scalar unary op are the same.
