2010-04-13ffvertex: don't touch tex coords if coord replace is enabled.Dave Airlie
The fixed function vertex program shouldn't need to deal or touch tex coords if stuffing is enabled. Though I'm not 100% this won't break assumption made elsewhere it seems like the correct thing to do, and makes r300g point sprites a lot easier to implement. draw: fix point-sprite when vertex program is used. This commit regressed draw, so fix it as well to help bisection. Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-02-19Replace the _mesa_*printf() wrappers with the plain libc versionsKristian Høgsberg

This may break the SUNOS4 build, but it's no longer relevant.
2010-02-04gallium: add point size clamp to implementation limits in vertex shaderRoland Scheidegger
The point size min/max registers (unused by mesa state tracker) were removed since most hardware couldn't do much with them. However, we don't want to have to rely on hw to do point size clamping correctly to implementation dependent limits, hence have to do that in the vertex shader. This should also solve a potential problem with (non-AA) points smaller than 1.0 which according to OGL still have size 1.0. Note that OGL point rendering is odd, in particular point sprites are rasterized differently to points. Some hardware might support those different modes, but in any case the different clamping values used for smooth/multisampled/sprite enabled points might help a bit for hw which rasterizes points the same as point sprites. Also tweak mesa's ff to vertex shader translation so don't have to clamp twice in case of point attenuation.
2009-12-22mesa: Remove _mesa_exit wrapper for exit().Eric Anholt
It does nothing else while being less useful than exit() because it lacks attributes that real exit() has.
2009-11-19mesa: Remove gratuitous padding in prog_dst_register.Eric Anholt
The padding was there to indicate the amount of space left from the number of expected bytes in the struct minus allocated bits. But uint bitfields get packed so that they don't cross uint boundaries, and we ended up allocating an extra dword to hold the pad field!
2009-11-17Merge branch 'outputswritten64'Ian Romanick
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.

2009-06-30mesa: fix material inputs in ffvertex_prog.cKeith Whitwell
Varying material inputs were not being picked up from the same slots where the VBO code is currently placing them (GENERIC0 and above). Most often they were just being ignored.
2009-05-08mesa: more complete fix for transform_invarient glitchesKeith Whitwell
Add a new flag mvp_with_dp4 in the context, and use that to switch both ffvertex.c and programopt.c vertex transformation code to either DP4 or MUL/MAD implementations.
2009-05-08mesa/main: set PREFER_DP4 to match position_invarient codeKeith Whitwell
This is a quick fix for z fighting in quake4 caused by the mismatch between vertex transformation here and in the position_invarient code. Full fix would be to make this driver-tunable and adjust both position_invarient and ffvertex_prog.c code to respect driver preferences.
2009-04-14mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul
There's really no need for two negation fields. This came from the GL_NV_fragment_program extension. The new, unified Negate bitfield applies after the absolute value step.
2009-03-31mesa: fix bug in GPU codegen for fixed-function two-sided lightingBrian Paul
The 'dots' register wasn't getting properly un-negated and un-swizzled after emitting the code for back-face lighting. So, if more than one light source was enabled, the specular exponent for the next light source was wrong. During execution we were evaluating pow(x, y) where y was negative instead of positive. This led to the outcome being zero or NaN. This fixes the occasional black triangles seen in isosurf when hacked to enable two-sided lighting.

2008-12-31mesa: increase max texture image units and GLSL samplers to 16Brian Paul
The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.
