[PATCH] D53927: [AArch64] Enable libm vectorized functions via SLEEF

[Naoki Shibata via Phabricator via llvm-commits]

> Where, when, how and by whom are these #pragmas inserted? Are they silently inserted by clang? Do they have to be manually inserted in existing code?
>  What is the effect of these #pragmas? The ARM closed-source commercial compiler requires OpenMP. How will these #pragmas be implemented in the open-source clang? Will they import OpenMP interfaces in the open-source clang as well?
>  If importing OpenMP interfaces is not triggered by the insertion of these #pragmas, why is the argument to -fveclib called 'openmp'? I would find it baffling to have to type -fveclib=openmp on compile-line, but ending up not using OpenMP.

I think you should post these questions as a reply to the RFC.
