It's a pity though, based on what I understood from the website, that it's only producing binaries which can be linked to other than actually generating C / C++ code. That would be great for LTO, but also allow for better inspection of the generated SIMD code prior to compilation to ensure that all code is compiled by the same compiler. I guess the best way to inspect the artefacts prior to assembly is via LLVM IR.
I'm pretty happy that Intel chose to implement this based on LLVM. I'd have expected this to be sitting on top of icc.
