[cfe-dev] System z vector language extensions for 3.7 branch?

[Ulrich Weigand]

Hi Hans,

thanks!   Just a quick update: it turns out the sanitizer build bots
uncovered an uninitialized variable access.  I've now fixed this in
r243644, and the build bot is green again.  So if this feature is
backported, please add that revision as well.

Sorry for the extra confusion ...

Bye,
Ulrich
