[PATCH] D57504: RFC: EVL Prototype & Roadmap for vector predication in LLVM

[David Greene via Phabricator via llvm-commits]

greened added inline comments.


================
Comment at: docs/Proposals/VectorPredication.rst:19
+
+The Explicit Vector Length (EVL) extension [EvlRFC]_ can be a first step towards native vector predication.
+The EVL prototype in this patch demonstrates the following concepts:
----------------
This document seems to overload "EVL" to mean both predication and an explicit vector length.  Of course predication can be used to simulate the effects of a vector length value on targets that don't have a way to specify an explicit vector length.

Can we keep the two concepts distinct in this document?  It's confusing to see "EVL" when discussing predication.  In particular, everything in `SelectionDAG` uses the "EVL" name to represent both concepts.  Can we come up with something more accurate?
