From 8a52f03f5deeb36ea4d58d56fbb711a2004d7587 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 25 Jun 2016 18:45:28 -0700 Subject: [PATCH] vc4: Enable dead CF elimination. Now that we're about to start generating control flow in our NIR, we want this in place. It optimizes things frequently in the CS, when the GL VS has control flow that doesn't affect the vertex position. --- src/gallium/drivers/vc4/vc4_program.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/gallium/drivers/vc4/vc4_program.c b/src/gallium/drivers/vc4/vc4_program.c index 5d036eb2604..8305459454b 100644 --- a/src/gallium/drivers/vc4/vc4_program.c +++ b/src/gallium/drivers/vc4/vc4_program.c @@ -1337,6 +1337,7 @@ vc4_optimize_nir(struct nir_shader *s) NIR_PASS(progress, s, nir_copy_prop); NIR_PASS(progress, s, nir_opt_dce); + NIR_PASS(progress, s, nir_opt_dead_cf); NIR_PASS(progress, s, nir_opt_cse); NIR_PASS(progress, s, nir_opt_peephole_select); NIR_PASS(progress, s, nir_opt_algebraic); -- 2.30.2
