it seems moderation didn't approve the phabricator mails for D12834.
(I have no intention to be subscribed to the list just to get
phabricator mails through. For now I am subscribed but disabled
mail delivery -.-)
So the patch is available at http://reviews.llvm.org/D12834
I also added a test case which shows that substitution is not
working correctly right now.
PS: I think contributing to llvm is way to complex. First I attatch
patches in the bug tracker, and it takes ages to get a reaction - and
them I'm simply told to send to the ML. Then you want me to use
phabricator, and then I get no feedback again - because moderation
blocked emails from an internal system, and it seems nobody is looking
at phabricator directly.
This is not something I look forward to go through again; my
motiviation to contribute further is rather low.
