From: Eric Anholt Date: Thu, 20 Dec 2018 15:45:58 +0000 (-0800) Subject: v3d: Hook up some shader-db output to GL_ARB_debug_output. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=696f63f1b472acd5efe32910c714469728fb5162;p=mesa.git v3d: Hook up some shader-db output to GL_ARB_debug_output. This allows the original shader-db project's run.c runner to parse things easily, and is probably a good thing to have for GL_ARB_debug_output in general. I formatted it more like Intel's so I can mostly reuse their report script. --- diff --git a/src/broadcom/compiler/nir_to_vir.c b/src/broadcom/compiler/nir_to_vir.c index ada0dd69921..b6dd188778a 100644 --- a/src/broadcom/compiler/nir_to_vir.c +++ b/src/broadcom/compiler/nir_to_vir.c @@ -1895,6 +1895,8 @@ ntq_emit_loop(struct v3d_compile *c, nir_loop *loop) c->loop_break_block = save_loop_break_block;
