2009-12-29glsl: added uniform initializer checkBrian Paul
GLSL 1.10 disallows initializers for uniforms but GLSL 1.20 and later allows them. This patch uses the #version directive to allow/disallow uniform initializers. This addresses bug 25807, but piglit also needs to be fixed to specify the GLSL version in the shader.

2009-12-18glsl: clear out shader code before compilingBrian Paul
When we start compiling a shader, first free the existing gl_program. This (mostly) fixes the piglit glsl-reload-source test. Without this change, we were actually appending the new GPU code onto the previous program.

2009-09-29glsl: rewrite sqrt(x) intrinsic to handle x=0Brian Paul
Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a divide by zero if x=0 and wind up with unpredictable results. Now use CMP instruction to test for x<=0 and return zero in that case.

2009-09-14glsl: remove extra #version directives from concatenated shader sourcesBrian Paul
When we concatenate shaders to do our form of poor-man linking, if there's multiple #version directives, preprocessing fails. This change disables the extra #version directives by changing the first two chars to //. This should help with some Wine issues such as bug 23946.

2009-08-12glsl: remove duplicate frag input entryBrian Paul
2009-08-12Merge branch 'new-frag-attribs'Brian Paul
This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these attributes were packed with the FOG attribute. That made things complicated elsewhere.
2009-08-12glsl: add gl_Vertex, gl_Normal, etc to list of active attributesBrian Paul
If a vertex shader uses gl_Vertex, gl_Normal, etc, we need to include them when the user queries the list of active attributes. Before this we were just including the user-defined attributes.
2009-08-12glsl: move predefined shader input/output info/code to slang_builtin.cBrian Paul
This is a more logical place for this code. Also add some functions for querying vertex shader input names, types, etc.
2009-07-29mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul
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...

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.

These options can be used to force vertex/fragment shaders to be no-op shaders (actually, simple pass-through shaders). For debug/test purposes.

2009-07-09glsl: do const parameter optimization for array element actual parametersBrian Paul
When a function parameter is const-qualified we can avoid making a copy of the actual parameter (we basically do a search/replace when inlining). This is now done for array element params too, resulting in better code (fewer MOV instructions). We should allow some other types of function arguments here but let's be conservative for the moment.

gl_NormalMatrix is the inverse transpose of the modelview matrix, but as every matrix here needs to be transposed, we end up with {MODELVIEW_MATRIX, INVERSE}.

2009-06-26glsl: overhaul 'return' statement handlingBrian Paul
A new node type (SLANG_OPER_RETURN_INLINED) is used to denote 'return' statements inside inlined functions which need special handling. All glean glsl1 tests pass for EmitContReturn=FALSE and TRUE.
2009-06-26glsl: predicate assignments according to __returnFlagBrian Paul
Fixes glean "function with early return (3)" case (when EmitContReturn=FALSE).
