2008-05-14fix some additional program refcounting bugsBrian Paul
cherry-picked from master
2008-05-06gallium: implement full reference counting for vertex/fragment programsBrian
Use _mesa_reference_vert/fragprog() wherever we assign program pointers. Fixes a memory corruption bug found with glean/api2 test. Another memory bug involving shaders yet to be fixed...
2008-04-23gallium: fix potential divide by zero in fog computationBrian Paul
It's legal for Fog.Start == Fog.End and conformance testing does so.
2008-04-16mesa: added internal post color matrix scale/bias varsBrian Paul
2008-04-14fix GL_ARB_texture_rectangle breakageBrian Paul
2008-04-14mesa: define #extension GL_ARB_texture_rectangleDavid Flynn
2008-04-07mesa: call _mesa_remove_varying_reads() after compiling vertex shadersBrian
2008-04-07mesa: new _mesa_remove_varying_reads() functionBrian
We'll apply this function to GLSL vertex programs. In GLSL it's legal to read and write varying (output) vars in a vertex shader. But reading from an output register isn't supported by all hardware. This routine examines the vertex program for that condition and rewrites it to use temporary registers where needed.
2008-04-07mesa: added _mesa_insert_instructions()Brian
Also, use new _mesa_free_instructions() in a few places.
2008-04-07mesa: added _mesa_free_instructions()Brian
2008-04-04mesa: no longer combine vertex/fragment shader parameters/uniformsBrian
GLSL Vertex and fragment shaders now have independent parameter buffers. A new gl_uniform_list is used to keep track of program uniforms and where each uniform is located in each shader's parameter buffer. This makes better use of the space in each buffer and simplifies shader linking.
2008-04-04mesa: new functions for managing list/index of uniformsBrian
2008-04-04gallium: make sure to set the SamplersUsed field for bitmap/drawpixels shadersBrian Paul
Also, make sure that field is copied/updated in the program clone and combine functions. Without this we weren't getting SAMP declarations in the TGSI shaders.

cherry-picked from master
2008-03-27Fix state.texgen parsing error (bug 12313).Brian
Replace *(*inst++) with *(*inst)++ in a few places. Cherry-picked from master.
2008-03-25mesa: fix some issues in _mesa_combine_programs()Brian Paul
Use a temporay register to connect outputs of first program to inputs of second program. Also, fix bug in replace_registers(): didn't search/replace DstReg.
2008-03-25mesa: append fog instructions after parsing if a fog option is setBrian Paul
Drivers don't have to worry about it then.
2008-03-25mesa: when negating scalar src args, use NEGATE_XYZW, not NEGATE_XBrian Paul
This makes things easier on the back-end when generating GPU code.
2008-03-22use ctx->Driver.DeleteProgram() in a few more placesBrian
2008-03-17only set InputsRead bit if input is really usedMarkus Amsler
2008-03-14mesa: init tmpNode to zerosBrian Paul
2008-03-14mesa: fix emit_clamp() so that we don't use an output register as temporaryBrian Paul
IR_CLAMP is decomposed into OPCODE_MIN+OPCODE_MAX. Allocate a temporary register for the intermediate value so we don't inadvertantly use an output register (which are write-only on some GPUs).
2008-03-13mesa: fix (harmless?) assignment in assertKeith Whitwell
2008-03-12mesa: set SamplersUsed bitmask when parsing ARB fragment programsBrian

2008-01-01fix a memleakBrian
2007-12-07Move _mesa_init_glsl_driver_functions() into shader_api.cBrian
This allows making a bunch of functions static, and removes a state tracker dependency on driverfuncs.c

Generic version of cache code from texenvprogram.c and t_vp_build.c Not used by those files just yet, will also be used for pixel_transfer programs.
