[LLVMdev] Adding masked vector load and store intrinsics
> So %passthrough can *only* be undef or zeroinitializer?
No, it can be any value including undef and zeroinitializer.
We considered, while designing, zero and merge semantics and decided that merge semantics is better because it covers zero semantics if you use zeroinitializer in the %paththru.

[LLVMdev] Adding masked vector load and store intrinsics
Hi,
We would like to add support for masked vector loads and stores by introducing new target-independent intrinsics. The loop vectorizer will then be enhanced to optimize loops containing conditional memory accesses by generating these intrinsics for existing targets such as AVX2 and AVX-512. The vectorizer will first ask the target about availability of masked vector loads and stores. The SLP
