2009-02-11glsl: allow setting arrays of samplers in set_program_uniform()Brian Paul
Arrays of sampler vars haven't been tested much and might actually be broken. Will need to be revisited someday. Another fix for bug 20056.
2009-02-11glsl: raise GL_INVALID_OPERATION for glUniform(location < -1)Brian Paul
location = -1 is silently ignored, but other negative values should raise an error. Another fix for bug 20056.
2009-02-11glsl: rework _mesa_get_uniform[fi]v() to avoid using a fixed size ↵Brian Paul
intermediate array
2009-02-11glsl: fix glUniform() array bounds error checkingBrian Paul
If too many array elements are specified, they're to be silently ignored (don't raise a GL error). Fixes another issue in bug 20056.
2009-02-11glsl: fix incorrect size returned by glGetActiveUniform() for array elements.Brian Paul
Fixes one of the issues in bug 20056.
2009-02-11mesa: Use the stdio wrappers.José Fonseca
snprint symbol does not exist in Windows.
2009-02-09re-add MSAA supportBrian Paul
(cherry picked from commit f7d80aa00611917bc8ce637136d982b151b8f44f) This also involved adding the new MSAA fields to driCreateConfigs(). Also, re-add prog_instructions->Sampler field for i965 driver. Will have to revisit that.

2009-02-06glsl: new MESA_GLSL env var for GLSL debugging featuresBrian Paul
Replaces the VERBOSE_GLSL, VERBOSE_GLSL_DUMP flags which only worked in debug builds. MESA_GLSL will work both in debug and non-debug builds. Also add facility to dump glUniform() calls to stdout.
2009-02-06mesa: tweak output of _mesa_write_shader_to_file()Brian Paul
Enclose GPU code in comments to the file can be re-fed back into GLSL compiler.
2009-02-06Revert "mesa: meaningless whitespace change to see if git's working (ignore)"Brian Paul
This reverts commit b2e779988eeb595187933fe2122d86f8ccfe059c. I didn't mean to push this stuff yet. I'm having a bad git day...

2009-02-04glsl: use _slang_var_swizzle() in a few places to simplify the code.Brian Paul
2009-02-04glsl: remove unused prototypeBrian Paul
2009-02-04glsl: replace assertion with conditional in _slang_pop_var_table()Brian Paul
We were hitting the assertion when we ran out of registers, which can happen. Also, add some additional assertions and freshen up some comments.
2009-02-02mesa: fix GLSL issue preventing use of all 16 generic vertex attributesBrian Paul
Only 15 actually worked before since we always reserved generic[0] as an alias for vertex position. The case of vertex attribute 0 is tricky. The spec says that there is no aliasing between generic vertex attributes 0..MAX_VERTEX_ATTRIBS-1 and the conventional attributes. But it also says that calls to glVertexAttrib(0, v) are equivalent to glVertex(v). The distinction seems to be in glVertex-mode versus vertex array mode. So update the VBO code so that if the shader uses generic[0] but not gl_Vertex, route the attribute data set with glVertex() to go to shader input generic[0]. No change needed for the glDrawArrays/Elements() path. This is a potentially risky change so regressions are possible. All the usual tests seem OK though.
2009-02-02glsl: update program->InputsRead when referencing input attributesBrian Paul
This info will be used in the linker for allocating generic vertex attribs.

2009-01-14Treat image units and coordinate units differently.Ian Romanick
Previously MaxTextureUnits was used to validate both texture image units and texture coordinate units in fragment programs. Instead, use MaxTextureCoordUnits for texture coordinate units and MaxTextureImageUnits for texture image units. Fixes bugzilla #19468.

2009-01-10glsl: force creation of new scope for for-loop bodyBrian Paul
Fixes regression in progs/demos/convolution.c due to loop unrolling. This also allows the following to be compiled correctly: for (int i = 0; i < n; i++) { int i; ... } This fix is a bit of a hack, however. The better fix would be to change the slang_shader.syn grammar. Will revisit that...
2009-01-10glsl: replace 0/1 with GL_FALSE/GL_TRUEBrian Paul
2009-01-09glsl: make minimum struct size = 2, not 1Brian Paul
1-component structs such as "struct foo { float x; }" could get placed at any position within a register. This caused some trouble computing the field offset which assumed all struct objects were placed at R.x. It would be unusual to hit this case in normal shaders.
