From e0e94026a0648d6b33d6b7cf2b9b01429cf945e4 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 11 Mar 2011 09:25:22 -0700 Subject: mesa: move location of some geometry program limits The gl_program_constants struct is for limits that are applicable to any/all shader stages. Move the geometry shader-only fields into the gl_constants struct. Remove redundant MaxGeometryUniformComponents field too. --- src/mesa/main/context.c | 18 ++++++++++-------- src/mesa/main/get.c | 12 ++++++------ src/mesa/main/mtypes.h | 21 +++++++++++---------- src/mesa/main/shaderapi.c | 2 +- src/mesa/program/ir_to_mesa.cpp | 2 +- 5 files changed, 29 insertions(+), 26 deletions(-) diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 5d581c84002..ca74284ca89 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -486,7 +486,6 @@ init_program_limits(GLenum type, struct gl_program_constants *prog) prog->MaxTemps = MAX_PROGRAM_TEMPS;
