2010-03-18gallivm/llvmpipe: added lp_rast_shader_inputs::facing and pass throughBrian Paul
The triangle rasterizer sets this field to indicate front/back-facing. It gets passed into the generated fragment code as another parameter. Used now for stencil front/back selection but will also be used for fragment shaders in general (see TGSI_SEMANTIC_FACE). With this commit two-sided stenciling mostly works but there's still a bug or two...
2010-03-13llvmpipe: Obey rasterization rules.José Fonseca
Replicates softpipe.
2010-03-13llvmpipe: setup_context -> lp_setup_contextJosé Fonseca
Otherwise IDEs and debuggers have trouble distinguishing from softpipe's setup_context.
2010-03-03llvmpipe: Store the original triangle coordinates in the debug build.José Fonseca
For debugging purposes only.
2010-02-11llvmpipe: Clamp both extremes of triangles to framebuffer size.José Fonseca
Fix segmentation fault when triangles crossed the axis.

2010-01-21llvmpipe: consolidate lp_scene_alloc_aligned() callsBrian Paul
Use just one call instead of four. Good for a few more fps.
2010-01-21llvmpipe: re-use a1 var in linear_coef()Brian Paul
2010-01-21llvmpipe: area is an int here, not floatBrian Paul
2010-01-21llvmpipe: manually unroll the inputs.step[] setup codeBrian Paul
Good for a few more fps in some tests.
2010-01-21llvmpipe: added simple perf/statistics counting facilityBrian Paul
Currently counting number of tris, how many tiles of each size are fully covered, partially covered or empty, etc. Set LP_DEBUG=counters to enable. Results are printed upon context destruction.

2010-01-15llvmpipe: implement scissor test in triangle setupBrian Paul
2010-01-15llvmpipe: remove lp_rast_triangle::min/max fieldsBrian Paul
These values aren't needed outside the do_triangle_ccw() function.

2010-01-13llvmpipe: minor assorted clean-upsBrian Paul
2010-01-13llvmpipe: Reset the bin when shading a whole tile with an opaque shader.José Fonseca
2010-01-13llvmpipe: tweak subpixel_snap() arithmeticBrian Paul
This adjustment fixes some rasterization differences between llvmpipe and softpipe (and other renderers).
2010-01-12llvmpipe: clamp maxx,maxy to framebuffer size (in terms of tiles)Brian Paul
In some corner cases the right-most / bottom-most vertex can be right on the edge of the framebuffer. Because the maxx, maxy vals are computed with a series of float/int, pixel/tile transformations we can end up with maxx >= scene->x_tiles or maxy >= scene->y_tiles. This leads to putting data into bins that never get processed, or reset. This becomes stale data that can lead to segfaults. Clamping fixes this.

2009-12-16llvmpipe: do final the pixel in/out triangle test in the fragment shaderBrian Paul
The test to determine which of the pixels in a 2x2 quad is now done in the fragment shader rather than in the calling C code. This is a little faster but there's a few more things to do. Note that the step[] array elements are in a different order now. Rather than being in row-major order for the 4x4 grid, they're in "quad-major" order. The setup of the step arrays is a little more complicated now. So is the course/intermediate tile test code, but some lookup tables help with that. Next steps: - early-cull 2x2 quads which are totally outside the triangle. - skip the in/out test for fully contained quads - make the in/out comparison code tighter/faster.
2009-12-13llvmpipe: rename bins to sceneKeith Whitwell
It was pretty confusing having an entity named "bin" and another named "bins", not least because sometimes there was a need to talk about >1 of the "bins" objects, which couldn't be pluralized any further... Scene is a term used in a bunch of places to talk about what a binner operates on, so it's a decent choice here.
2009-12-09llvmpipe: use new lp_setup_get_current_bins() functionBrian Paul
This stub function will interface to the queue system...
2009-12-04llvmpipe: reorganization of binning data structions and funtionsBrian Paul
New lp_bins struct contains all bin information. More move bin-related code into lp_bin.[ch] Use new/updated bin-access functions to hide implementation details. The result is more/cleaner separation between the setup and rast components. This will make double-buffering of the bins easier, etc.
2009-12-04llvmpipe: move bin-related structures and functions into new lp_bin.[ch]Brian Paul
And put lp_ prefixes on some functions.
2009-12-04llvmpipe: remove lp_rast_triangle::oneoverarea fieldBrian Paul
Makes lp_rast_triangle a little smaller (now 280 bytes on a 32-bit system).
2009-12-04llvmpipe: bin state-change commandsBrian Paul
Previously, each triangle had a pointer to the state to use for shading. Now we insert state-change commands into the bins. When we execute one of those commands we just update a 'current state' pointer and use that pointer when calling the jit shader. When inserting state-change commands into a bin we check if the previous command was also a state-change command and simply replace it. This avoids accumulating useless/redundant state-change commands.
2009-12-04llvmpipe: fix typo, whitespaceBrian Paul
2009-12-04llvmpipe: dynamic allocation of triangle a0/dadx/dady arraysBrian Paul
Much less memory per triangle now.

2009-10-09llvmpipe: use union lp_cmd_rast_arg directly, rather than through a pointerKeith Whitwell
The union itself consists of pointers. We don't need to be passing pointer to pointers.
