[Openmp-commits] [PATCH] D46842: [OpenMP][libomptarget] Make bitcode library building depend on clang and llvm-linker being available

Can we double check this LLVM IR backward compatible thing? My understanding is that it is not that good, at least for the major versions.

So in my mind, we have two scenarios when the bc file is involved.

1. when we do in-tree build, the runtime bc file should be compiled by the just-built compiler (the runtime should always as new if not newer than the compiler it intends for.)
2. when we do out-of-tree build, the runtime bc file will be compiled by the building compiler, and hoping the runtime will work with that version (i.e you are using a newer runtime than the building compiler.)
