Dear All,
I created the LLVM 1.5 release branch this afternoon. It is called release_15.
I would prefer that people hold off on committing non-release changes to the mainline until after the release is complete (as people sometimes request that I fold more mainline changes into the branch). However, if you need to commit something, you can do so.
Within the next day or two, I'll be asking people working on some of the LLVM ports if they can test out the release branch.
