LLVM 3.7 Delivers OpenMP 3.1 Support, ORC JIT API, New Optimizations

Posted by Soulskill on from the onward-and-upward dept.

An anonymous reader writes: LLVM 3.7 was released today as the newest six-month update. LLVM 3.7 has OpenMP 3.1 support via Clang, a new On-Request Compilation JIT API, the Berkeley Packet Filter back-end was added, the AMDGPU back-end now supports OpenGL 4.1 when paired with Mesa 11.0, and many other functional changes. Early benchmarks against GCC show its performance quite competitive with GCC5, even superior in some workloads, and should be more competitive in scientific applications with there now being OpenMP support.

  1. Oooh, OpenMP support ... nice ! by UnknownSoldier · · Score: 3, Interesting

    I've been forced to manually install gcc 5.x on OSX simply because clang didn't support OpenMP.

    This is great news. Now I can support both compilers on OSX.

  2. OpenMP 4.0 by tanderson92 · · Score: 4, Interesting

    They *just now* implemented OpenMP 3.1, a standard 4 years old. OpenMP 4.0 which is now more than 2 years old is unaddressed while GCC has had it for some time(indeed, they recently added support for OpenACC).

    Somehow I don't think scientific users are going to be lining up to use it
