Erik,<br>
<br>
I've fixed this in my local repository; so this will be fixed in the next patchset release.<br>
<br>
The cause of this error was that I did not understand that the 'index' argument of LLVM's extract-vector-element operation could be non-constant. I've added an implementation for this 'general' case as sldi (left shift by 5) -> qvlpclsx<br>
-> qvfperm. The constant index case is still handled by qvesplati as it was before.<br>
<br>
Thanks again,<br>
Hal<br>
