2011-01-31texture_builtins.py: Fix a warning about mixed tabs/spaces.Kenneth Graunke
2011-01-31texture_builtins.py: Generate texture*Offset functions.Kenneth Graunke
2011-01-31texture_builtins.py: Generalize the "use_proj" field to support offsets.Kenneth Graunke
Rather than passing "True", pass a bitfield describing the particular variant's features - either projection or offset. This should make the code a bit more readable ("Proj" instead of "True") and make it easier to support offsets in the future.
2011-01-31texture_builtins.py: Refactor coordinate dimension calculations.Kenneth Graunke
For offsets, we'll want the straight sampler dimensionality, without the +1 for array types. Create a new function to do that; refactor.
2011-01-31glsl: Change texel offsets to a single vector rvalue.Kenneth Graunke
Having these as actual integer values makes it difficult to implement the texture*Offset built-in functions, since the offset is actually a function parameter (which doesn't have a constant value). The original rationale was that some hardware needs these offset baked into the instruction opcode. However, at least i965 should be able to support non-constant offsets. Others should be able to rely on inlining and constant propagation.
2010-08-13glsl2: Rework builtin function generation.Kenneth Graunke
Each language version/extension and target now has a "profile" containing all of the available builtin function prototypes. These are written in GLSL, and come directly out of the GLSL spec (except for expanding genType). A new builtins/ir/ folder contains the hand-written IR for each builtin, regardless of what version includes it. Only those definitions that have prototypes in the profile will be included. The autogenerated IR for texture builtins is no longer written to disk, so there's no longer any confusion as to what's hand-written or generated. All scripts are now in python instead of perl.
2010-08-10texture_builtins.py: Remove useless comments.Kenneth Graunke
2010-08-09texture_builtins.py: Fix cut and paste errors in function names.Kenneth Graunke
Some signatures were being generated with the wrong function name.
