[llvm-dev] questions about backport to 3.8/3.9/4.0
Hi, I want to backport the following three patches (currently in trunk 5.0) to 3.8/3.9/4.0: https://reviews.llvm.org/rL305560 https://reviews.llvm.org/rL305608 https://reviews.llvm.org/rL306685 Some BPF users want them since their product needs to work on old linux distribution which has older versions of LLVM. Could somebody (maybe Tom Stellard or others) help clarify whether it is possible and what is the procedure/timeline for backporting? Thanks! Yonghong
I have no experience on backporting. However, the patches you want only involves BPF backend itself, I don't see any particular trouble of backporting. I would suggest you start working on the latest LLVM release, i.e., 4.0, then run the testsuite to make sure there is no regression.

[llvm-dev] questions about backport to 3.8/3.9/4.0
Thanks. That is good suggestion. I will start to work on 4.0 now. It would be good to know the 4.0.x patch release schedule and how to contribute. I found this email containing backporting timeline for 4.0.1 (already done): http://lists.llvm.org/pipermail/llvm-dev/2017-March/111530.html>From email, it is not clear to me whether we have upcoming4.0.2 or not.
