Intel in 2016.  Intel has switched to a LLVM-based compiler back end.  The
migration to LLVM was just getting started when I retired.  Intel has been
contributing to LLVM, particularly in the areas of parallelization, loop
transformation, and interprocedural optimization.  Some of this technology
has Multiflow roots.
