From 1ee2ad584c95233b5cdbbed9fa5997533dc80276 Mon Sep 17 00:00:00 2001 From: Hyunjun Ko Date: Tue, 19 Nov 2019 07:20:10 +0000 Subject: [PATCH] freedreno/ir3: enable nir_opt_loop_unroll on a6xx If precision lowering happens at GLSL IR, loop_analysis at IR doesn't work as expected since it can't handle things like: "(expression bool < (expression float16_t f2fmp (var_ref ndx) ) (constant float16_t (1.000000)) )" So we'd rather do this optimization at the NIR stage.
