From 296fde31aadcb021a76295597a7d1ac366c1c62b Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Fri, 21 Jan 2022 13:10:55 +0100 Subject: [PATCH] broadcom/compiler: allow vectorization to larger scalar type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Allow to vectorize operations from a smaller bit-size into scalar operations of a larger bit-size. This allows us to turn 2x8-bit into a equivalent scalar 16-bit load/store.
