2009-12-12swrast: Silence uninitialized variable warnings in s_triangle.cVinson Lee1-0/+6
2009-12-12swrast: Initialize tex_coords in handle_sample_op.Vinson Lee1-1/+1
2009-10-07swrast: s/GLfloat/GLuint/ in bzero()Brian Paul1-1/+1
2009-10-07swrast: add missing returnsBrian Paul1-0/+2
2009-09-24Merge branch 'mesa_7_5_branch' into mesa_7_6_branchBrian Paul1-3/+8
2009-09-23swrast: add lod bias when texture samplingBrian Paul1-2/+7
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()
2009-09-23swrast: fix typo in partial derivatives parameter passingBrian Paul1-1/+1
2009-09-21Merge branch 'mesa_7_5_branch' into mesa_7_6_branchBrian Paul1-2/+2
2009-09-21swrast: fix cube face selectionBrian Paul1-2/+2
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.
2009-09-03swrast: wrap comment to 80 columns, remove dead codeBrian Paul1-57/+6
2009-09-03mesa: consolidate PBO map/unmap helpersBrian Paul3-6/+6
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 Paul1-1/+1
This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
2009-08-31swrast: can't use deferred texture/shading if using KIL instructionBrian Paul1-0/+3
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.

2009-08-27swrast: fix incorrect tri culling in selection/feedback mode.Brian Paul2-7/+9
See bug 16866.
2009-08-12Merge branch 'new-frag-attribs'Brian Paul2-18/+15
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.
2009-08-08swrast: replace GLenum, GLint with GLbitfield for buffer varsBrian Paul1-3/+3

2009-08-05mesa: make _mesa_clip_blit() a shared functionBrian Paul1-180/+3
2009-07-31swrast: fix incorrect texcoord attribute testBrian Paul1-3/+3
2009-07-29mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul2-17/+14
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...
2009-06-16mesa: fix REMAINDER() macroBrian Paul1-1/+1
The results were incorrect for some negative values of A. See bug 21872.

2009-06-10swrast: fix state validation bug for changing program constantsBrian Paul1-0/+1
Add _NEW_PROGRAM_CONSTANTS to _SWRAST_NEW_DERIVED. This makes sure that we update the fragment shader's constants when state vars (such as point size) changes. Fixes the progs/glsl/points.c demo.
2009-06-03swrast: always do span clipping in _swrast_write_rgba_span()Brian Paul1-14/+4
It's possible for mis-behaving vertex programs to produce vertex data with very large/NaN values. This doesn't get handled reliably by the clipper code so we may try to rasterize triangles that extend beyond the viewport/window. Always clip spans to avoid invalid memory accesses later.
2009-05-12swrast: update/restore the opt_sample_rgb/rgba_2d() functionsBrian Paul1-15/+9
2009-05-07mesa: move the NullBufferObj from GLcontext to gl_shared_stateBrian Paul1-5/+5
Since shared array objects may point to the null/default buffer object, the null/default buffer object should be part of the shared state.
2009-05-07swrast: fix span clipping bugBrian Paul2-22/+71
If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
2009-04-28swrast: add missing break in clamp_rect_coord_linear()Brian Paul1-0/+1
See bug 21461.
2009-04-21swrast: simplify state update logic for fragment shader const buffersBrian Paul1-25/+2
2009-04-20swrast: fix pointer arithmetic error in get_texel_array()Brian Paul1-2/+1
This came from commit 1b2ab023673261b4b942e1126c0b599d02fbd4a0
2009-04-09swrast: remove some unneeded CHAN_TYPE!=GL_FLOAT codeBrian Paul1-7/+0
2009-04-07swrast: fix point rendering function selectionBrian Paul1-1/+4
Need to clamp default point size to min/max range before checking if it's one. Fixes glean pointAtten test.
2009-04-07swrast: restore !shader check around add_specular()Brian Paul1-4/+6
Fixes a regression from commit 76ac75af8e5481b498981c133836efa2101be2dc.
2009-04-06swrast: more texcombine clean-upsBrian Paul1-21/+10
2009-04-06swrast: asst. clean-ups in texcombine codeBrian Paul1-26/+19
2009-04-06swrast: fix secondary color add for glBitmapBrian Paul3-11/+30
Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
2009-04-06swrast: fix incorrect arithmetic for GL_ADD_SIGNED/GL_COMBINE4_NV modeBrian Paul1-6/+6
2009-04-06swrast: fix texture border color interpretationBrian Paul1-30/+68
The texture border color must be interpreted according to the texture's base format. For example, for a GL_ALPHA texture, sampling the border color should return (0,0,0,borderAlpha). This wasn't an issue here until I removed the legacy texenv code (we always use the combiner path now).
2009-04-03mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul1-2/+2
It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
2009-04-01swrast: remove unused integer lerp functionsBrian Paul1-43/+1
2009-04-01swrast: remove old texture_apply() code; always use texture combine codeBrian Paul3-403/+22
