[LLVMdev] LLC ARM Backend maintainer

[Tanya Lattner]

Exactly as Jim said :) 

I'm only talking about releases and release blockers. Its also a bit of a grey area when you are talking about just ARM codgen tests in the regression test suite because those should always be passing regardless of what target/os you are testing on (assuming you built the arm backend which the release team typically does). As it stands now we don't have ARM as a supported target just because there is no qualification plan for it (ie. no one running the test suite or some other benchmarks on an ARM device for example) and no real support to qualify it. If someone wants to initiate this process, it can be talked about post-3.0.

If, during release testing, a regression is found on ARM compared to 2.9 results, it is not required by process to be considered a release blocker. That does not mean features can or should be enabled which knowingly break ARM. That's an entirely different situation.

If ARM is not a supported target, can I mark these tests as 'XFAIL' and enable vector-select support in LLVM ?

Maybe I just need to better understand LLVM release process, I've seen a mail in this list about it.
