* meta: Drop the src == dst restriction on meta glBlitFramebuffer().Eric Anholt2014-02-121-20/+0
| | | | | | | | | | | | | | From the GL_ARB_fbo spec: If the source and destination buffers are identical, and the source and destination rectangles overlap, the result of the blit operation is undefined. As far as I know, that's the only thing that would have been of concern for this. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* mesa: Make TexImage error cases about internalFormat more informative.Eric Anholt2014-02-121-7/+13
| | | | | | | | | | I tripped over one of these when debugging meta, and it's a lot nicer to just see the internalFormat being complained about. v2: Drop a note in the other errors path that there is one early return.

* meta: Rename the "sampler" stuff to "blit shader".Eric Anholt2014-02-121-41/+40

* i965/vec4: Fix confusion between SWIZZLE and BRW_SWIZZLE macros.Francisco Jerez2014-02-123-4/+4
| | | | | | | | | | | | Most of the VEC4 back-end agrees on src_reg::swizzle being one of the BRW_SWIZZLE macros defined in brw_reg.h, except in two places where we use Mesa's SWIZZLE macros. There is even a doxygen comment saying that Mesa's macros are the right ones. They are incompatible swizzle representations (3 bits vs. 2 bits per component), and the code using Mesa's works by pure luck. Fix it.

* i965/fs: Remove fs_reg::sechalf.Francisco Jerez2014-02-124-12/+16
| | | | | | | | | The same effect can be achieved using ::subreg_offset. Remove the less flexible alternative and define a convenience function to keep the fs_reg interface sane. Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>
* i965/fs: Remove fs_reg::smear.Francisco Jerez2014-02-127-24/+30
| | | | | | | | | The same effect can be achieved using a combination of ::stride and ::subreg_offset. Remove the less flexible ::smear to keep the data members of fs_reg orthogonal. Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>

| | | | | | | | | | | v2: Some improvements for copy propagation with non-contiguous register strides and mismatching types. v3: Add example of the situation that the copy propagation changes are intended to avoid.

* i965/fs: Add support for sub-register byte offsets to the FS back-end IR.Francisco Jerez2014-02-125-21/+46
| | | | | | | | | | | | | It would be nice if we could have a single 'reg_offset' field expressed in bytes that would serve the purpose of both, but the semantics of 'reg_offset' are quite complex currently (it's measured in units of one, eight or sixteen dwords depending on the register file and the dispatch width) and changing it to bytes would be a very intrusive change at this stage. Add a separate 'subreg_offset' field for now. Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Paul Berry <[email protected]>

* glsl: Add image built-in function generator.Francisco Jerez2014-02-121-0/+251
| | | | | | | | | | | | | | | | | | Because of the combinatorial explosion of different image built-ins with different image dimensionalities and base data types, enumerating all the 242 possibilities would be annoying and a waste of .text space. Instead use a special path in the built-in builder that loops over all the known image types. v2: Generate built-ins on GLSL version 4.20 too. Rename '_has_float_data_type' to '_supports_float_data_type'. Avoid duplicating enumeration of image built-ins in create_intrinsics() and create_builtins(). v3: Use a more orthodox approach for passing image built-in generator parameters. v4: Cosmetic changes.

* glsl/ast: Forbid declaration of image variables in structures and uniform ↵Francisco Jerez2014-02-121-0/+10
| | | | | | | | | | | | | | | | | blocks. Aggregating images inside uniform blocks is explicitly disallowed by the standard, aggregating them inside structures is not (as of GL 4.4), but there is a similar problem as with atomic counters: image uniform declarations require either a "writeonly" memory qualifier or an explicit format qualifier, which are explicitly forbidden in structure member declarations. In the resolution of Khronos bug #10903 the same wording applied to atomic counters was decided to mean that they're not allowed inside structures -- Rejecting image member declarations within structures seems the most reasonable option for now.
