* mesa: Change "BRIAN PAUL" to "THE AUTHORS" in license text.Kenneth Graunke2013-04-231-1/+1

I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

* 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.

| | | | | | The clamping for these values depends on whether we're drawing AA or non-AA points, lines. Defer clamping until drawing time. Drivers could compute and keep clamped AA and clamped non-AA values if desired.

| | | | | | | Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.

| | | | | | | | | | | which is automatically generated to match the current texture environment state. Introduces a new value ctx->FragmentProgram._Active which is true when either _Enabled is true or there is such a fragment program ready to run. To test out on a driver running the software rasterizer, set MESA_TEX_PROG=t in the environment. It goes without saying that performance is lower for the software rasterizer in this mode.
