From 2e853ca23c8670246dd4efcee0706f68097652f7 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 5 Aug 2010 10:09:12 -0700 Subject: glsl2: Add a pass for removing unused functions. For a shader involving many small functions, this avoids running optimization across all of them after they've been inlined post-linking. Reduces the runtime of linking and running a fragment shader from Yo Frankie from 1.6 seconds to 0.9 seconds (-44.9%, +/- 3.3%). --- src/glsl/linker.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src/glsl/linker.cpp') diff --git a/src/glsl/linker.cpp b/src/glsl/linker.cpp index 94db57d6a5..f9e24ca0f1 100644 --- a/src/glsl/linker.cpp +++ b/src/glsl/linker.cpp @@ -1286,6 +1286,7 @@ link_shaders(struct gl_shader_program *prog) progress = false; progress = do_function_inlining(ir) || progress; + progress = do_dead_functions(ir) || progress; progress = do_if_simplification(ir) || progress; progress = do_copy_propagation(ir) || progress; progress = do_dead_code_local(ir) || progress; -- cgit v1.2.3
