[PATCH] D155193: [LangRef] vscale_range implies the vscale is power-of-two

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

The approach taken here seems fine.  It gives the optimization opportunities we want now, but leaves open an escape hatch for non-power-of-two widths if some target does end up needing them.  (SVE does require power-of-two lengths, but they made that decision very late; there seems to be some room for other architectures to make a different choice.)
