* mesa/glsl: Separate parsing logic from _mesa_get_uniform_location.Paul Berry2013-02-042-61/+28
| | | | | | | | | | | | | | | | The parsing logic is moved to a new function in the GLSL module, parse_program_resource_name(). This name was chosen because it should eventually be useful for handling everything that OpenGL 4.3 calls "program resources" (e.g. uniforms, vertex inputs, fragment outputs, and transform feedback varyings). Future patches will make use of this function for linking transform feedback varyings. NOTE: This is a candidate for the 9.1 branch.

* mesa: don't use format chooser code for glCompressedTexImageBrian Paul2013-02-041-2/+12
| | | | | | | | | | When glCompressedTexImage is called the internalFormat is a specific format for the incoming image and the the hardware format should be the same (since we never do format transcoding). So use the simpler _mesa_glenum_to_compressed_format() function. This change is also needed for the next patch. Note: This is a candidate for the stable branches.

| | | | | | | | | | | | This reverts commit 2906e2034c9d674601960a5b586b6e986e6ef04f. Fixes a regression in the glean depthStencil test. Reverting this does not affect any tests in es3conform, so a more recent patch must have also fixed the failure this one was intended to fix.

Add check for extension enable in get_tex_level_parameter_buffer. v5: Fix position in gl_API.xml.

* mesa: Remove rounding bias in _mesa_float_to_half()Chad Versace2013-01-241-29/+37
| | | | | | | | | | | | | | | | | | | | | | | Not all float32 values can be exactly represented as a float16. _mesa_float_to_half() rounded such intermediate float32 values to zero by truncating unrepresentable bits in the mantissa. This patch improves _mesa_float_to_half() by rounding intermediate float32 values to the nearest float16; when the float32 is exactly between two float16 values we round to the one with an even mantissa. This behavior is preferred over the old behavior because: - It has reduced bias relative to the old behavior. - It reproduces the behavior of real hardware: opcode F32TO16 in Intel's GPU ISA. - By reproducing the behavior of the GPU (at least on Intel hardware), compile-time evaluation of constant packHalf2x16 GLSL expressions will result in the same value as if the expression were executed on the GPU.

* glsl: Eliminate ambiguity between function ins/outs and shader ins/outsPaul Berry2013-01-241-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the three ir_variable_mode enums: - ir_var_in - ir_var_out - ir_var_inout with the following five: - ir_var_shader_in - ir_var_shader_out - ir_var_function_in - ir_var_function_out - ir_var_function_inout This eliminates a frustrating ambiguity: it used to be impossible to tell whether an ir_var_{in,out} variable was a shader in/out or a function in/out without seeing where the variable was declared in the IR. This complicated some optimization and lowering passes, and would have become a problem for implementing varying structs. In the lisp-style serialization of GLSL IR to strings performed by ir_print_visitor.cpp and ir_reader.cpp, I've retained the names "in", "out", and "inout" for function parameters, to avoid introducing code churn to the src/glsl/builtins/ir/ directory. Note: a couple of comments in the code seemed to indicate that we were planning for a possible future in which geometry shaders could have shader-scope inout variables. Our GLSL grammar rejects shader-scope inout variables, and I've been unable to find any evidence in the GLSL standards documents (or extensions) that this will ever be allowed, so I've eliminated these comments.

| | | | | | | | | | | | | | | | | | | | | | When performing a ReadPixels operation, we may be reading from a buffer that stores alpha values, but that is actually representing a buffer with no alpha channel. In this case, while rebasing the values, touch up all alpha values read to 1.0.

Regardless, as far as I can tell now, these functions don't get changed, by grepping for calls to SET_* to change the dispatch table (we do change functions in GLvertexformat at runtime, but those don't overlap with this set of functions).
