From d78f65cd6cf04dafcf50b4014de9d28546badcfb Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 2 Nov 2006 21:43:06 +0000 Subject: Fix fragment program fog problems found with Glean. 1. add PROGRAM_CONSTANT to switch() in src_vector(). 2. use _mesa_append_fog_code() to handle fog options in i915ProgramStringNotify(). 3. Re-enable some vertex attribute emit code that was previously disabled in i915ValidateFragmentProgram(). --- src/mesa/drivers/dri/i915tex/i915_fragprog.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'src/mesa/drivers/dri/i915tex') diff --git a/src/mesa/drivers/dri/i915tex/i915_fragprog.c b/src/mesa/drivers/dri/i915tex/i915_fragprog.c index 2ddcbc43255..8772e702307 100644 --- a/src/mesa/drivers/dri/i915tex/i915_fragprog.c +++ b/src/mesa/drivers/dri/i915tex/i915_fragprog.c @@ -39,6 +39,7 @@ #include "program_instruction.h" #include "program.h" +#include "programopt.h" @@ -127,6 +128,7 @@ src_vector(struct i915_fragment_program *p, Index]); break; + case PROGRAM_CONSTANT: case PROGRAM_STATE_VAR: case PROGRAM_NAMED_PARAM: src = @@ -928,6 +930,12 @@ i915ProgramStringNotify(GLcontext * ctx, */ ctx->Driver.Enable(ctx, GL_FRAGMENT_PROGRAM_ARB, ctx->FragmentProgram.Enabled); + + if (p->FragProg.FogOption) { + /* add extra instructions to do fog, then turn off FogOption field */ + _mesa_append_fog_code(ctx, &p->FragProg); + p->FragProg.FogOption = GL_NONE; + } } _tnl_program_string(ctx, target, prog); @@ -1001,7 +1009,10 @@ i915ValidateFragmentProgram(struct i915_context *i915) EMIT_PAD(1); } -#if 0 + /* XXX this was disabled, but enabling this code helped fix the Glean + * tfragprog1 fog tests. + */ +#if 1 if ((inputsRead & FRAG_BIT_FOGC) || i915->vertex_fog != I915_FOG_NONE) { EMIT_ATTR(_TNL_ATTRIB_FOG, EMIT_1F, S4_VFMT_FOG_PARAM, 4); } -- cgit v1.2.3
