Hi Chris

I sent an e-mail a while ago but I made a mistake when transforming it from
daily digest into a single e-mail and you may not have seen it.

lomp is already used for the "lightweight OpenMP" (LOMP) implementation,
which is for PPC64, BlueGene, and Z-series systems.
Here are some references to it:


One important note is that LOMP supports the KMP* interface and can be (and
currently is) used as a OpenMP library for LLVM.
Unless you feel strongly for re-using the name, I would rather prefer LLOMP
to avoid confusion.

      What name is desirable instead of iomp?  Do we want to link via…
      -lnotintelomp ( just kidding J )
      … Some other name?  I get the feeling someone outside of Intel should
      make this choice.

Why not -lomp?
