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/ir_optimization.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/glsl/ir_optimization.h') diff --git a/src/glsl/ir_optimization.h b/src/glsl/ir_optimization.h index 55ec327193..e0c0715cf5 100644 --- a/src/glsl/ir_optimization.h +++ b/src/glsl/ir_optimization.h @@ -36,6 +36,7 @@ bool do_copy_propagation(exec_list *instructions); bool do_dead_code(exec_list *instructions); bool do_dead_code_local(exec_list *instructions); bool do_dead_code_unlinked(exec_list *instructions); +bool do_dead_functions(exec_list *instructions); bool do_div_to_mul_rcp(exec_list *instructions); bool do_function_inlining(exec_list *instructions); bool do_if_return(exec_list *instructions); -- cgit v1.2.3
