[LLVMdev] Vector-select status update
...fects the way
the LLVM Type-Legalizer legalizes vectors.
This flag is not turned on by default because there are still a few open issues with non-x86 targets (mainly ARM).
If you are interested in having vector-select support then there are a few things that you can do to help:
1. Have a look at pr10902 and try to resolve the last few open issues.
2. Compile your application using the -promote-elements flag and report any performance regressions (and performance gains!).

Hi Nadav,
> The new type-legalization mode (-promote-elements) which enables vector-select in LLVM (and a nice perf boost for several workloads), is currently disabled because of a _single_ bug in the ARM codegen which makes a few tests fail. If ARM is not a supported target, can I mark these tests as 'XFAIL' and enable vector-select support in LLVM ?
Which testcase is it?
