* Merge branch 'outputswritten64'Ian Romanick2009-11-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

* Revert "Store clipping distance for user clip planes as part of vertex ↵Ian Romanick2009-10-221-15/+0
| | | | | | | | | | processing" This reverts commit f058b25881e08c9d89a33345e5c84e1357396932. This change is completely wrong in so many ways. When clip distances are generated as part of vertex processing, they must be interpolated to perform clipping. Geometric clipping goes right out the window.
* Store clipping distance for user clip planes as part of vertex processingIan Romanick2009-10-131-0/+15
| | | | | | | | | | | | | | Once the clipping distance is calculated and stored per vertex, the distances can be re-used when clipping is actually performed. This doesn't have any immediate benefit, but it paves the way for implementing gl_ClipDistance in vertex shaders and result.clip[] in vertex programs. This has not produces any oglconform regressions on my G31 system which uses software TNL. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Brian Paul <brianp@vmware.com>
* mesa: move call to init_c_cliptest() from enable.c to tnl module.Brian Paul2009-09-091-0/+2
| | | | Fixed gallium build breakage.
* mesa: Add support for ARB_depth_clamp.Eric Anholt2009-09-081-2/+4
| | | | | This currently doesn't include fixing up the cliptests in the assembly paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.

* Enable texture sampling for vertex programs/shaders.Brian2007-04-171-11/+47
| | | | | | | This is a bit of a hack for now because the tnl module is using the swrast module to fetch texels. The texture fetch/filter code should probably be moved into the main/ module since it doesn't really depend upon other swrast code.
* cleanups for t_vb_program.cRoland Scheidegger2007-04-171-13/+19
| | | | | | use VertexProgram._Current instead of VertexProgram.Current in a few more places. Only fixup fogc and psiz in case this is really a nv program (others are fine if undefined), and fix this case up so the values actually get written.

* GLSL fixes:Michal Krol2006-03-211-1/+1
| | | | | | | | | | | | | | | | | | - generate error on NULL pointers in glShaderSourceARB; - reinstall program object, if current, in glLinkProgramARB; - vertex and fragment shaders are optional in program object; - floor asm was wrongly computed for x86 back-end; - allow for (void) idiom in function prototypes; - all fixed-state uniforms are updated; - local variable initializers are working; - implement texture* and shadow* functions for vertex processor; - generate error if too many arguments in general constructor; - trim unused data in general constructor; - struct r-value field select was badly relocated; Changes: - add derived state gl_fog_attrib::_Scale; - add derived state gl_light::_CosCutoffNeg;

* Unify vertex/fragment program instuctions.Brian Paul2005-11-051-1/+1

* Store compiled vertex program representations in a pointer in theKeith Whitwell2005-06-091-1/+2
| | | | | | | | | | | | | vertex_program struct. Allow switching between regular and vertex_program implementations of fixed function TNL with the MESA_TNL_PROG environment var (previously this required recompilation). Ensure program compilation only references program data, not the wider context. This means that compiled programs only need to be invalidated when the program string changes, not on other state changes.
* Simplify the pipeline_stage structureKeith Whitwell2005-04-221-97/+10
| | | | | | | | | | - remove input/output fields, input tracking removed. - remove state fields, the validate function now called on every statechange. - add an explicit 'create' function. Add in code to build vertex program to implement current t&l state. Still disabled, but turn on with a #define in t_vp_build.h.
