More OpenMP Support Has Been Hitting LLVM's Clang

For full OpenMP support in LLVM/Clang that's hoped for Clang 3.7 after some OpenMP pragmas made it in for LLVM Clang 3.6. It looks like the 3.7 release will indeed deliver better OMP support with more functionality having been implemented in recent days.

Intel has been largely leading the recent OpenMP push in LLVM/Clang and it's starting to pan out for mainline LLVM/Clang developers. Alexey Bataev of Intel in Russia has been landing some of the OpenMP enablement within mainline Clang. OpenMP is a popular parallel programming API that with OpenMP 4.0 also supports targeting GPUs and other devices beyond just CPUs. Ultimately with LLVM/Clang OpenMP the goal is to support all targets.

Among the fresh additions are code generation for "omp sections" and "omp section" directives, code generation for the "omp task" directive, improved generating debug info, code generation for the #pragma omp atomic write, and various other work.

LLVM Clang 3.7 is expected for release later this year.
