Phoronix: RISC-V Auto-Vectorization Support For The GCC Compiler Started

A set of patches sent out this morning lay out the initial foundation for RISC-V auto-vectorization support within the GNU Compiler Collection (GCC)...

LLVM's RISC-V support is years ahead.

But unfortunately, most Linux distributions are built with gcc.

Not surprising. But if you really do run Linux on a RISC-V processor, you're probably best compiling the most performance critical packages yourself.

You could use Gentoo or NixOS.

This stuff is not measured in years, and the techniques of interest are documented. The GCC RVV vectorizer will not take as long as the LLVM one did to become useful.
