[LLVMdev] Policy for applying fixes to released branches?

[Dan Liew]

Hi,

I was wondering what the policy is for applying fixes to released branches.

In particular I have fix that would be useful to have in LLVM 3.5. I
recently found and fixed a bug [1] in the way CMake files are
generated by the Autoconf/Makefile system and fixed this in r217484.

I figured it would be more sensible to ask about this in a thread
separate from [2] because this is a much more general question.

So what should I do here?

Should I also commit this patch to the branches/release_35 or am I not
allowed to do this and instead should downstream (e.g. Debian, Arch..
etc) just apply the patch when building their packages?

Even if I add the patch to the release branch I don't think most
distributions will get it because they'll probably use the tarballs
which won't have the patch. I'm pretty sure it would be unhelpful
rebuild the tarballs because downstream won't know that they need to
rebuild their packages.

@Sylvestre : IIRC you maintain LLVM Debian packages so I figured your
insight would be helpful.
