[llvm-dev] buld_vector and shuffle_vector DAG nodes

[Rail Shafigulin via llvm-dev]

I'm not quite clear what BUILD_VECTOR and SHUFFLE_VECTOR instructions do. I
understand that they somehow build a vector and shuffle a vector, but how
exactly it translates into a given target, that I can not figure out. I
also tried reading code for other targets but I really lack experience.
Would anyone be able to give a clear explanation, maybe even an example if
possible?

Any help is appreciated.
