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.

2009-10-29mesa: Mostly fix swrast's ARB_depth_clamp support.Eric Anholt
I'd written a testcase for the hard part of the extension enablement, so naturally the easy stuff was completely broken. There are still issues, as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets piglit depth-clamp-range closer to success.

2009-10-28swrast: fix RGB, RGBA texturing codeBrian Paul
Fix backward component ordering for RGB textures. Only optimize RGBA texture case if running little endian. This restriction could be lifted with a little work.
2009-10-28swrast: check for single texture unit in _swrast_choose_triangle()Brian Paul
2009-10-28swrast: clean up and remove dead code in triangle functionsBrian Paul
2009-10-28swrast: fix texel decoding in opt_sample_rgba_2d()Brian Paul
2009-10-08mesa: remove a bunch of gl_renderbuffer fieldsBrian Paul
_ActualFormat is replaced by Format (MESA_FORMAT_x). ColorEncoding, ComponentType, RedBits, GreenBits, BlueBits, etc. are all replaced by MESA_FORMAT_x queries.

2009-10-03swrast: Move up state validation in _swrast_ReadPixels.Michel Dänzer
This ensures the driver won't map the wrong set of textures.
2009-09-30swrast: fix some texformat regressionsBrian Paul
Need to be careful with component ordering for MESA_FORMAT_RGB888 and MESA_FORMAT_RGBA8888.
2009-09-30mesa: remove GLchan-based formats; use hw 8-bit/channel formats insteadBrian Paul
Removed: MESA_FORMAT_RGBA, RGB, ALPHA, LUMINANCE, LUMINANCE_ALPHA, INTENSITY.
2009-09-30mesa: replace gl_texture_format with gl_formatBrian Paul
Now gl_texture_image::TexFormat is a simple MESA_FORMAT_x enum. ctx->Driver.ChooseTexture format also returns a MESA_FORMAT_x. gl_texture_format will go away next.
2009-09-30mesa/main: New feature FEATURE_queryobj.Chia-I Wu
It merges FEATURE_ARB_occlusion_query and FEATURE_EXT_timer_query, and follows the feature conventions.

2009-09-23swrast: add lod bias when texture samplingBrian Paul
Mostly fixes progs/demos/lodbias when MESA_TEX_PROG=1. But the LOD still seems off by -1 or so. May be an issue with the params passed to _swrast_compute_lambda()

2009-09-21swrast: fix cube face selectionBrian Paul
If arx and ary are equal, we still want to choose from one of them, and not arz. This is the same as Michal's softpipe fix.

2009-09-08mesa: Add support for ARB_depth_clamp.Eric Anholt
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.
2009-09-03swrast: wrap comment to 80 columns, remove dead codeBrian Paul
2009-09-03mesa: consolidate PBO map/unmap helpersBrian Paul
Instead of _mesa_map_readpix_pbo() use _mesa_map_pbo_source(). Instead of _mesa_map_drawpix_pbo() and _mesa_map_bitmap_pbo() use _mesa_map_pbo_dest().
2009-08-31swrast: fix selection/feedback regressionBrian Paul
This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
2009-08-31swrast: can't use deferred texture/shading if using KIL instructionBrian Paul
If the fragment program uses KIL, we have to execute it before z/stencil testing. Otherwise, deferred texture/shading lets us skip shading for pixels that fail z/stencil testing.

2009-08-12Merge branch 'new-frag-attribs'Brian Paul
This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these attributes were packed with the FOG attribute. That made things complicated elsewhere.

2009-07-29mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul
Previously, the FOGC attribute contained the fragment fog coord, front/back- face flag and the gl_PointCoord.xy values. Now each of those things are separate fragment program attributes. This simplifies quite a few things in Mesa and gallium. Need to test i965 driver and fix up point coord handling in the gallium/draw module...
