* swrast: Fix fixed-function fragment processingChad Versace2012-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i965, _mesa_ir_link_shader is never called. As a consequence, the current fragment program (ctx->FragmentProgram->_Current) exists but is invalid because it has no instructions. Yet swrast continued to attempt to use the empty program. To avoid using the empty program, this patch 1) defines a new function, _swrast_use_fragment_program, which checks if the current fragment program exists and differs from the fixed function fragment program, and, when appropriate, 2) replaces checks of the form if (ctx->FragmentProgram->_Current == NULL) with if (_swrast_use_fragment_program(ctx)) Fixes the following oglconform regressions on i965/gen6: api-fogcoord(basic.allCases.log) api-mtexcoord(basic.allCases.log) api-seccolor(basic.allCases.log) api-texcoord(basic.allCases.log) blend-separate(basic.allCases) colorsum(basic.allCases.log) The tests were ran with the GLXFBConfig: visual x bf lv rg d st colorbuffer sr ax dp st accumbuffer ms cav id dep cl sp sz l ci b ro r g b a F gb bf th cl r g b a ns b eat ---------------------------------------------------------------------------- 0x021 24 tc 0 32 0 r y . 8 8 8 8 . . 0 24 8 0 0 0 0 0 0 None (Note: I originally believed that the hunk in _swrast_update_fragment_program was unnecessary. But it is required to fix blend-separate.) Note: This is a candidate for the 8.0 branch.

| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.

| | | | | | | | | Replace struct gl_texure_object's Dimension w/ Target field. Added _EnabledUnits to struct gl_texture_attrib - the _ReallyEnabled field is obsolete, but still present for now. This effectively removes the 8-texture units limit, 32 units now possible, but unlikely! New TEXTURE_1D/2D/3D/CUBE/RECT_BIT tokens for unit->_ReallyEnabled field. Updated device drivers to use ctx->Texture._EnabledUnits.

As a part of this, collapsed the decomposition of quads into triangles inside swrast to be hardwired into _swrast_Quad; removed s_quads.[ch].

Moved several derived values used only by swrast into that directory. Removed direct calls to swrast_flush() from vbrender.c -- pushed into ctx->Driver.RenderFinish. Optimized flat-shading case in swrast_setup.
