To make our lives a little easier, could you tell us what you tested
and how we can reproduce your results?

Also: Is your patch expected to be bit-exact? If yes, do you
have a script that allows to compare C and vsx code?
If not, how did you test your code?
(Or does fate cover these conversions? I wouldn't expect so.)

Thank you, Carl Eugen
