2010-03-08i965: Fix up the handling of point sprite coordinate replacement.Eric Anholt
The code was walking over the regs of pairs of attributes and checking whether the attribute with a given reg index had point sprite enabled. So the point sprite setup code was rarely even getting executed. Instead, we need to determine which channels of a reg need point sprite coordinate replacement. In addition, it was multiplying the attribute by 1/w, when it's supposed to cover (0, 1) in each direction regardless of w, and it wasn't filling in the Z and W components of the texcoord as specified. Fixes piglit point-sprite and the spriteblast demo. Bug #24431, #22245.
2009-11-17Merge branch 'outputswritten64'Ian Romanick
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.

2009-10-29i965: make brw_sf_prog_key::sprite_origin_lower_left one bitBrian Paul
Shrinks size of key to 8 bytes from 12. Note that progs/demos/spriteblast.c is still broken.
2009-06-12i965: interpolate colors with perspective correction by defaultBrian Paul
...rather than with linear interpolation. Modern hardware should use perspective-corrected interpolation for colors (as for texcoords). glHint(GL_PERSPECTIVE_CORRECTION_HINT, mode) can be used to get linear interpolation if mode = GL_FASTEST.

it ensures there are sufficient registers for all subroutines.
