<br>
This is a continuation of r167064 ( <a href="http://llvm.org/viewvc/llvm-project?view=revision&revision=167064" target="_blank">http://llvm.org/viewvc/llvm-project?view=revision&revision=167064</a> ).<br>
That patch started to fix PR14221 ( <a href="http://llvm.org/bugs/show_bug.cgi?id=14221" target="_blank">http://llvm.org/bugs/show_bug.cgi?id=14221</a> ), but was not completed, so we have a chunk of extra code that is preventing further improvements.<br>
<br>
If everything looks ok here, I can submit a follow-on patch to fix sqrtsd (double-precision square root).<br>
<br>
I'm not locating a Phab address for Manman Ren, so I'll send a follow-on mail.<br>
