* mesa: change _mesa_find_free_register() to find multiple free regsBrian Paul2010-02-011-2/+9
| | | | | | | | | | | | | | | | | Before, _mesa_find_free_register() would scan the given shader to find a free/unused register of the given type. But subsequent calls would return the same register again. This caused a failure in the _mesa_remove_output_reads() function which sometimes needs several free temps. Now use a new function which build a vector of 'used' flags and another function which searches that vector for an unused register starting at a position that's incremented for each call. Fixes fd.o bug 26317. Note that a regression test for this has been added to the glean/glsl1 test. (cherry picked from commit e0d01c9d7f46ccd531f8dd1a04c5ac067200ef1e)

* | Merge branch 'outputswritten64'Ian Romanick2009-11-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul2009-07-291-1/+0
| | | | | | | | | | Previously, the FOGC attribute contained the fragment fog coord, front/back- face flag and the gl_PointCoord.xy values. Now each of those things are separate fragment program attributes. This simplifies quite a few things in Mesa and gallium. Need to test i965 driver and fix up point coord handling in the gallium/draw module...
* mesa: ensure UsesFogFragCoord value is set for non-glsl shadersKeith Whitwell2009-07-021-0/+1
| | | | | | With recent changes to support frontfacing in glsl, it is necessary to ensure that the UsesFogFragCoord value is accurate in all shaders. We were previously not setting it for fixed-function and ARB_fs shaders.
* mesa: more complete fix for transform_invarient glitchesKeith Whitwell2009-05-081-2/+117
| | | | | | 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.
* mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul2009-04-141-1/+1
| | | | | | 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.

| | | | | | | | | | | | | | use the same internal state as for vertex fog. From the old implemenentation, this changes a SUB+MUL into a MAD for linear fog, and saves a MUL for EXP/EXP2, plus saves a (constant) parameter. While here, fix the broken (forgotten) swizzling. (untested)
