[llvm-dev] questions about backport to 3.8/3.9/4.0

[陳韋任 via llvm-dev]

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.
