From c10a68522c400d48553dbd473b9778140842d9dd Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 13 Jul 2010 11:07:16 -0700 Subject: [PATCH] glsl2: When linking makes a variable not a varying output, make it ir_var_auto. This almost fixes glsl-unused-varying, except that the used varying gets assigned to the first varying slot (position). --- src/glsl/linker.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/glsl/linker.cpp b/src/glsl/linker.cpp index 90dc97bc535..c71c07d6e97 100644 --- a/src/glsl/linker.cpp +++ b/src/glsl/linker.cpp @@ -1052,7 +1052,10 @@ assign_varying_locations(gl_shader *producer, gl_shader *consumer) /* An 'out' variable is only really a shader output if its value is read * by the following stage. */ - var->shader_out = (var->location != -1); + if (var->location == -1) { + var->shader_out = false; + var->mode = ir_var_auto; + } } foreach_list(node, consumer->ir) { -- 2.30.2
