From d5be2acae379783c4aa31243e0a88a9e67e6ca7e Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Tue, 20 Jul 2010 11:29:46 -0700 Subject: linker: Link built-in functions instead of including them in every shader This is an invasive set of changes. Each user shader tracks a set of other shaders that contain built-in functions. During compilation, function prototypes are imported from these shaders. During linking, the shaders are linked with these built-in-function shaders just like with any other shader. --- src/glsl/glsl_parser_extras.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/glsl/glsl_parser_extras.h') diff --git a/src/glsl/glsl_parser_extras.h b/src/glsl/glsl_parser_extras.h index b50d9eea67..56f6e18e0b 100644 --- a/src/glsl/glsl_parser_extras.h +++ b/src/glsl/glsl_parser_extras.h @@ -125,6 +125,10 @@ struct _mesa_glsl_parse_state { /** Extensions supported by the OpenGL implementation. */ const struct gl_extensions *extensions; + + /** Shaders containing built-in functions that are used for linking. */ + struct gl_shader *builtins_to_link[16]; + unsigned num_builtins_to_link; }; typedef struct YYLTYPE { -- cgit v1.2.3
