* mesa: Make sure _TexEnvProgram points at the current ff fragment programIan Romanick2012-01-271-0/+9
| | | | | | | | | | | | | | At least one place, the _mesa_need_secondary_color function in state.h, uses this to make decisions. The next patch in this series will add another dependency. Ideally, this field would go away and be replace by a flag or something. NOTE: This is a candidate for the 8.0 branch.

* mesa: Track fixed-function fragment shader as a shaderIan Romanick2012-01-111-0/+10
| | | | | | | | | | | | Previously the fixed-function fragment shader was tracked as a gl_program. This means that it shows up in the driver as a Mesa IR program instead of as a GLSL IR program. If a driver doesn't generate Mesa IR from the GLSL IR, that program is empty. If the program is empty there is either no rendering or a GPU hang.

| | | | | | | | | | | | Replace the distinct struct gl_client_array members in gl_array_object by an array of gl_client_arrays indexed by VERT_ATTRIB_*. Renumber the vertex attributes slightly to keep the old semantics of the distinct array members. Make use of the upper 32 bits in VERT_BIT_*.

| | | | | | | | DD_POINT_SIZE was broken for quite some time, and the only driver (r200) relying on this no longer needs it. Both DD_POINT_SIZE and DD_LINE_WIDTH have no users left outside of debugging output, hence instead of fixing DD_POINT_SIZE setting just drop both of them - there was a plan to remove tricaps flags entirely at some point.

* mesa: new _NEW_PROGRAM_CONSTANTS flagBrian Paul2009-04-211-1/+35
| | | | | | | | | | | | | | | This state flag will be used to indicate that vertex/fragment program constants have changed. _NEW_PROGRAM will be used to indicate changes to the vertex/fragment shader itself, or misc related state. _NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's tracking GL state has changed. For example, if the projection matrix is in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS to be set. This will let to remove the need for dynamic state atoms in some drivers. For now, we still set _NEW_PROGRAM in all the places we used to. We'll no longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.
* mesa: Update texenv program when _NEW_ARRAYS is updated as well.Eric Anholt2009-04-151-1/+2
| | | | | | | | | | This fixes a regression in fbotest1 on 915, where a transition from color+vertex array enabled to texcoord0+vertex array enabled wouldn't trigger program update on the second _mesa_update_state of DrawArrays, and we'd sample a constant texcoord of 0,0,0,1 instead of the array. The double state update in DrawArrays from 1680ef869625dc1fe9cf481b180382a34e0738e7 still needs fixing.
