2007-03-19r300: Fix WRITEMASK handling when writing to result.depthNicolai Haehnle
This is a necessary change to emit the right instructions when writing to result.depth. However, even with this test, Z-write doesn't work properly, and I don't fully understand why. In addition to this, we'll at least have to disable early-Z, but even that doesn't seem to be enough.
2007-03-19r300: Streamlined fragment program LIT implementationNicolai Haehnle
Fix a bug in the LIT implementation (clamp exponent to 128, not 0.5) and change the implementation around. In theory, the new implementation needs as little as 5 instruction slots. Unfortunately, the dependency analysis in find_and_replace_slot is not strong enough to look at individual components of a register yet.
2007-03-19r300: Fix fragment program reorderingNicolai Haehnle
Do not move an instruction that writes to a temp forward past an instruction that reads the same temporary.
2007-03-19r300: Fragment program dumps format tex instructionsNicolai Haehnle
2007-03-19r300: Fix hw fragment program dumpNicolai Haehnle
Dumps of fragment programs were incorrect when the program consisted of multiple nodes. Also, improved the formatting a bit.
2007-03-19r300: Fix fragment program instruction pairing and register allocationNicolai Haehnle
There were a number of bugs related to the pairing of vector and scalar operations where swizzles ended up using the wrong source register, or an instruction was moved forward and ended up overwriting an aliased register. The new algorithm for register allocation is quite conservative and may run out of registers before necessary. On the plus side, It Just Works. Pairing is done whenever possible, and in more cases than before, so in practice this change should be a net win.

Making modifications while the editor spawned by git-commit was suspended didn't have the intended effect.
2007-03-19i915tex: Fix triple buffering after recent Mesa core changes.Michel Dänzer
Remove superfluous _mesa_resize_framebuffer call which is now harmful because it causes the third renderbuffer to have width/height 0, so Mesa refuses to render to it. In the long term, it would be nice to remove the hack in intel_alloc_window_storage in favour of a proper Mesa interface for flipping between more than two colour buffers.

2007-03-16Assorted fixes for dealing with zero-size frame/renderbuffers.Brian
In xmesa_check_and_update_buffer_size() handle xmctx==NULL correctly: still call _mesa_resize_framebufer(). If we don't we can wind up in a situation where the framebuffer size is non-zero but an attached renderbuffer size is still initialized to zero. This inconsistancy can later cause problems. Check for zero-size renderbuffers in update_color_draw_buffers() and update_color_read_buffer(). See bug 7205.
2007-03-16Colortable re-org.Brian
The pixel transfer path has three color table lookups. Use an array [3] to store that info, rather than separate variables.

Note that insert_wpos in r300_vertexprog.c is still a little flaky and could be improved.

2007-03-14Re-org of gl_pixel_attrib struct.Brian
Reorder fields according to the order in which the pixel transfer operations take place. Improve comments. Move the pixel maps out of gl_pixel_attrib since they're not supposed to be pushed/popped by glPush/PopAttrib. New gl_pixelmap and gl_pixelmaps structs to contain the pixelmaps.

2007-03-13sync up t_vp_build.c brw_vs_tnl.c a bitRoland Scheidegger
Bring over the optimizations for fog and normalized spot dir from t_vp_build.c to brw_vs_tnl.c. Likewise, port a fix for point size calc from brw_vs_tnl.c to t_vp_build.c (use ABS(eyez) instead of -eyez). Leave the now differing point size calcs alone though, not sure what's better (it's basically MOV, ABS, MUL, DP3 vs. ABS, MAD, MAD).
2007-03-13enable ARB_vertex_buffer_object for more dri driversRoland Scheidegger
ARB_vertex_buffer_object looks like a useful extension even for old chips. The drivers should not need any code to be able to use this extension since they just use mesa's vbo code anyway. Newly enabled for i810, mach64, mga, r128, radeon, savage, sis and unichrome.
