[PATCH] D66199: [docs] loop pragmas

[Michael Kruse via Phabricator via cfe-commits]

Meinersbur added a comment.

Since this is user documentation, we should only add it here once it is true.



================
Comment at: docs/LanguageExtensions.rst:3068-3069
 
+There are loop hints that control transformations (e.g. vectorization, loop
+unrolling) and there loop hints that set transformation options (e.g.
+``vectorize_width``, ``unroll_count``).  Pragmas setting transformation options
----------------
`vectorize_width` also "controls" a transformation. Is it that in our interpretation, `vectorize(enable)` overrides the profitability heuristic by taking out the "do not apply at all" option without setting any other option?
