Intel ditches own compiler infrastructure and moves to LLVM

Intel is right now in the process of embracing LLVM and ditching their own compiler infrastructure. Affected languages are C, C++ and FORTRAN at least. This means that new Intel compilers will be under the hood re-branded LLVM ones, with some Intel additions on top.

Intel claims that benefits of that move are faster build time with Clang, and that they will add their own secret sauce to LLVM in terms of optimization technics. Most of these will get upstreamed, but not all if they are either too new or very specific to the Intel architecture. Intel also claims that their LLVM compilers beat the previous Intel compiler generation performance wise always by a good margin.

This is really ground breaking. It also means that as relevant compiler implementations there will be only left now GCC, LLVM and Microsoft's VisualStudio. This for sure is a big thing for the LLVM community.

 
There are also still the Portland Group compilers, now owned by someone else. I think they also use the LLVM framework as a frontend.
