* swrast: add missing call to _swrast_depth_bounds_test()Brian Paul2010-01-151-0/+7
| | | | | | | | We were calling this from the CI span function, but not the RGBA span function. I don't know of a test program for the GL_EXT_depth_bounds_test extension...
* swrast: fix broken _swrast_depth_clamp_span()Brian Paul2010-01-151-14/+27
| | | | | | | | | | The integer Z clamping range depends on the number of bits in the Z buffer because that's the scale factor used when we transform NDC coords by the viewport/depth range. Fixes fd.o bug #25972 but only for Z buffers up to a depth of 30 bits. Beyond that we get into messy integer overflow issues and things fall apart.

* swrast: use different temp array in _swrast_get_dest_rgba()Brian Paul2009-12-311-7/+3
| | | | | When using multiple color drawbuffers with blending/logicop/masking we were overwriting color values which we still needed.

* | Merge branch 'outputswritten64'Ian Romanick2009-11-171-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

* | mesa: Mostly fix swrast's ARB_depth_clamp support.Eric Anholt2009-10-292-12/+26
| | | | | | | | | | | | | | I'd written a testcase for the hard part of the extension enablement, so naturally the easy stuff was completely broken. There are still issues, as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets piglit depth-clamp-range closer to success.

| * | swrast: fix RGB, RGBA texturing codeBrian Paul2009-10-281-5/+11
| | | | | | | | | | | | | | | | | | Fix backward component ordering for RGB textures. Only optimize RGBA texture case if running little endian. This restriction could be lifted with a little work.

| | | | | | | | | | | | | | | | | | _ActualFormat is replaced by Format (MESA_FORMAT_x). ColorEncoding, ComponentType, RedBits, GreenBits, BlueBits, etc. are all replaced by MESA_FORMAT_x queries.
| * | swrast: fix some texformat regressionsBrian Paul2009-09-302-41/+49

| * | mesa: replace gl_texture_format with gl_formatBrian Paul2009-09-302-16/+16
| | | | | | | | | | | | | | | | | | Now gl_texture_image::TexFormat is a simple MESA_FORMAT_x enum. ctx->Driver.ChooseTexture format also returns a MESA_FORMAT_x. gl_texture_format will go away next.

| | * swrast: can't use deferred texture/shading if using KIL instructionBrian Paul2009-08-311-0/+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.
