[LLVMdev] LLC ARM Backend maintainer

No. Note the qualifying phrase "for releases" on Tanya's statement. 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.
