* Revert "mesa: Remove pointless comparison of unsigned integer with a ↵Vinson Lee2010-03-041-4/+9
| | | | | | | | | | | | | | negative constant." This reverts commit a05fdbcb719ac64e6be842372813f0f4ca2f4f93. Removing the comparison is wrong. The comparison with -1 should be changed to another value (probably PROGRAM_UNDEFINED) along with another change in the shader assembler. Conflicts: src/mesa/shader/prog_execute.c

* glsl: implement support for GL_EXT_texture_arrayBrian Paul2010-02-259-83/+246
| | | | | | | | GL_EXT_texture_array is different from the existing GL_MESA_texture_array support in that the former is only supported for GLSL, not fixed-function. The shadow compare versions of the sampler functions haven't been tested yet. The non-shadow versions have been tested with a new piglit test.

| | | | | | glapi/dispatch.h is a core Mesa header file. Move the header file to main/ to make this clear. It also becomes clear after this change that IN_DRI_DRIVER is only used in core Mesa to enable the remap table.

* mesa: Fix compiler warningsKarl Schultz2010-02-135-12/+12
| | | | | Add explicit casts, fix constant types, fix variable types. Fixes about 340 warnings in MSFT Visual Studio.
* glsl: implement layout qualifiersBrian Paul2010-02-131-19/+110
| | | | | | | | | | | | | For GL_ARB_fragment_coord_conventions. This only applies to gl_FragCoord and controls pixel center origin and pixel center integer. For example: layout (origin_upper_left, pixel_center_integer) varying vec4 gl_FragCoord; This features introduces the idea of re-declaring variables with a changed type. This may also apply to arrays in some cases but that's not implemented at this time.
* glsl: added type layout field and new type compare funcBrian Paul2010-02-132-2/+45
| | | | | Note: because of a weird dependency checking bug, a 'make clean' may be needed before recompiling.

| | | | | | | | | Both the #extension directive name and the preprocessor symbol start with the GL_ prefix. For example: ... New glean/glsl1 tests have been added to test the #extension feature.
* Merge branch 'gallium-nopointsizeminmax'Roland Scheidegger2010-02-092-0/+66

| * gallium: add point size clamp to implementation limits in vertex shaderRoland Scheidegger2010-02-042-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | mesa: add back-door support for cylindrical texture wrap modeBrian Paul2010-02-091-0/+1
| | | | | | | | | | | | | | | | | | If the texture priority field is 0.125 set the PROG_PARAM_BIT_CYL_WRAP flag. The gallium state tracker will look for this flag. This feature is only for testing purposes and may be remove at some point. But if it's useful we could write a GL/Mesa extension to expose it properly.

* | mesa: change ctx->Driver.ProgramStringNotify() to return GLbooleanBrian Paul2010-02-044-12/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | GL_TRUE indicates that the driver accepts the program. GL_FALSE indicates the program can't be compiled/translated by the driver for some reason (too many resources used, etc). Propogate this result up to the GL API: set GL_INVALID_OPERATION error if glProgramString() was called. Set shader program link status to GL_FALSE if glLinkProgram() was called. At this point, drivers still don't do any program checking and always return GL_TRUE.
* | mesa: check/clamp texture/program matrix accessesBrian Paul2010-02-031-2/+6
| | | | | | | | Further testing should reveal if any these assertions are hit...
* | mesa: change _mesa_find_free_register() to find multiple free regsBrian Paul2010-02-013-29/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
