proper linking. Previously, programs were translated independently during validation. The problem is the translation to TGSI format, which packs shader input/outputs into continuous slots, depends on which vertex program is being paired with which fragment shader. Now, we look at the outputs of the vertex program in conjunction with the inputs of the fragment shader to be sure the attributes match up correctly. The new 'linked_program_pair' class keeps track of the associations between vertex and fragment shaders. It's also the place where the TGSI tokens are kept since they're no longer per-program state but per-linkage. Still a few loose ends, like implementing some kind of hash/lookup table for linked_program_pairs.

2007-09-20checkpoint: TGSI_ATTRIB_x tokens no longer usedBrian
2007-09-19Checkpoint: replacement of TGSI_ATTRIB_x tokens with input/output semantics.Brian
TGSI_ATTRIB_x tokens still present and used in a few places. Expanded set of TGSI_SEMANTIC_x tokens for describing the meaning of inputs/outputs. These tokens are in a crude state ATM. Lots of #if 0 / disabled code to be removed yet, etc... Softpipe and i915 drivers should be in working condition but not heavily tested.
2007-09-18Checkpoint: rework shader input/output register mapping.Brian
This is a step toward removing TGSI_ATTRIB_ tokens. Basically, when translating Mesa programs to TGSI programs, pass in input and output register re-maps, plus interpolation info. There's some known breakage (cubemap.c) so more to be done...
2007-09-18Fix some issues with perspective-corrected interpolation.Brian
In mesa_to_tgsi.c, use TGSI_INTERPOLATE_PERSPECTIVE by default (to match post-transform vertex info convention). More to be done there... In sp_quad_fs.c, interpolate W in addition to Z. This fixes the divide by zero happening in perspective_interpolation() tgsi_exec.c As it was, we were only getting perspective correction of texture coords used by the TGSI_TEX instruction since it does a homogeneous divide. Other coords/varyings were incorrect.

Fix softpipe vertex attribute setup. Also, update vs constants when the projection matrix changes (fixes samples/prim.c)
2007-08-23Checkpoint: new vertex/fragment attribute namingBrian
Replace VF_ATTRIB_x with TGSI_ATTRIB_x When converting mesa programs to TGSI programs, also convert the InputsRead and OutputsWritten to a mask of TGSI_ATTRIB_ bits. Still need to do conversion for vertex programs...
