From f82f2fb3dc770902f1657ab1c22e6004faa3afab Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 2 Aug 2014 05:33:14 -0700 Subject: [PATCH] mesa: Actually use the Mesa IR optimizer for ARB programs. On Haswell, this cuts 1-3 instructions from 183 vertex shaders in "Shadowrun Returns", "Shatter", and "Trine 2." It adds 2 instructions to a single fragment shader in "Closure." total instructions in shared programs: 278803 -> 278546 (-0.09%) instructions in affected programs: 41930 -> 41673 (-0.61%) Signed-off-by: Kenneth Graunke Reviewed-by: Eric Anholt --- src/mesa/program/arbprogparse.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/mesa/program/arbprogparse.c b/src/mesa/program/arbprogparse.c index 5b9665091b6..7dec399a538 100644 --- a/src/mesa/program/arbprogparse.c +++ b/src/mesa/program/arbprogparse.c @@ -60,6 +60,7 @@ having three separate program parameter arrays. #include "prog_parameter.h" #include "prog_statevars.h" #include "prog_instruction.h" +#include "prog_optimize.h" #include "program_parser.h" @@ -84,6 +85,9 @@ _mesa_parse_arb_fragment_program(struct gl_context* ctx, GLenum target, return; } + if ((ctx->_Shader->Flags & GLSL_NO_OPT) == 0) + _mesa_optimize_program(ctx, &prog); + free(program->Base.String); /* Copy the relevant contents of the arb_program struct into the @@ -177,6 +181,9 @@ _mesa_parse_arb_vertex_program(struct gl_context *ctx, GLenum target, return; } + if ((ctx->_Shader->Flags & GLSL_NO_OPT) == 0) + _mesa_optimize_program(ctx, &prog); + free(program->Base.String); /* Copy the relevant contents of the arb_program struct into the -- 2.30.2
