From 4379dcc12d36bf9993a06c628c9426d4f54ba58d Mon Sep 17 00:00:00 2001 From: Erico Nunes Date: Sat, 10 Aug 2019 22:46:02 +0200 Subject: [PATCH] lima/ppir: enable vectorize optimization pp has vector units and some operations can be optimized when bundled together. Benchmarking this with piglit shaders shows that the instruction count can be greatly reduced on many examples with vectorize.
