Author: Eric Anholt <e...@anholt.net> Date: Thu Aug 5 10:13:10 2010 -0700 ir_to_mesa: Don't do function inlining until linking. Optimizations at compile time should generally be done with the goal of reducing instruction count so that other work, particularly linking, is less time-consuming if the shader is used multiple times. However, function inlining increases instruction count for the inlined function bodies without removing the original function body, since we don't know if it will be used at link time or not. Reduces the runtime of linking and executing a Yo Frankie fragment shader from 0.9 seconds to 0.5 seconds (-45.9%, +/- 2.2%, n=5). --- src/mesa/program/ir_to_mesa.cpp | 1 - 1 files changed, 0 insertions(+), 1 deletions(-) diff --git a/src/mesa/program/ir_to_mesa.cpp b/src/mesa/program/ir_to_mesa.cpp index 74996ae..299b11d 100644 --- a/src/mesa/program/ir_to_mesa.cpp +++ b/src/mesa/program/ir_to_mesa.cpp @@ -2604,7 +2604,6 @@ _mesa_glsl_compile_shader(GLcontext *ctx, struct gl_shader *shader) do { progress = false; - progress = do_function_inlining(shader->ir) || progress; progress = do_if_simplification(shader->ir) || progress; progress = do_copy_propagation(shader->ir) || progress; progress = do_dead_code_local(shader->ir) || progress; _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-commit
