* glsl: add support for explicit locations inside interface blocksTimothy Arceri2015-12-154-9/+105
| | | | | | | This change also adds explicit location support for structs and interfaces which is currently missing in Mesa but is allowed with SSO and GLSL 1.50+. Reviewed-by: Edward O'Callaghan <[email protected]>
* glsl: simplify interface matchingTimothy Arceri2015-12-151-108/+46
| | | | | | | | | | | | This makes the code easier to follow, should be more efficient and will makes it easier to add matching via explicit locations in the following patch. This patch also replaces the hash table with the newer resizable hash table this should be more suitable as the table is likely to only contain a small number of entries.

* nir: Fix number of indices on shared variable store intrinsics.Kenneth Graunke2015-12-141-1/+1
| | | | | | | | | | | | | Shared variables and input reworks landed around the same time. Presumably, this was some sort of mistake in rebase conflict resolution. This really only affects the num_indices field in nir_intrinsic_infos, which is rarely used. However, it's used by the printer. Found by inspection.

* glsl: assign varying locations to tess shaders when doing SSOIlia Mirkin2015-12-131-4/+4
| | | | | | | | | | | GRID Autosport uses SSO shaders. When a tessellation evaluation shader is passed through this, it triggers assertion failures down the line with unassigned varying locations. Make sure to do this when the first shader in the pipeline is not a vertex shader.

* nir: Get rid of *_indirect variants of input/output load/store intrinsicsJason Ekstrand2015-12-108-185/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is some special-casing needed in a competent back-end. However, they can do their special-casing easily enough based on whether or not the offset is a constant. In the mean time, having the *_indirect variants adds special cases a number of places where they don't need to be and, in general, only complicates things. To complicate matters, NIR had no way to convdert an indirect load/store to a direct one in the case that the indirect was a constant so we would still not really get what the back-ends wanted. The best solution seems to be to get rid of the *_indirect variants entirely. This commit is a bunch of different changes squashed together: - nir: Get rid of *_indirect variants of input/output load/store intrinsics - nir/glsl: Stop handling UBO/SSBO load/stores differently depending on indirect - nir/lower_io: Get rid of load/store_foo_indirect - i965/fs: Get rid of load/store_foo_indirect - i965/vec4: Get rid of load/store_foo_indirect - tgsi_to_nir: Get rid of load/store_foo_indirect - ir3/nir: Use the new unified io intrinsics - vc4: Do all uniform loads with byte offsets - vc4/nir: Use the new unified io intrinsics - vc4: Fix load_user_clip_plane crash - vc4: add missing src for store outputs - vc4: Fix state uniforms - nir/lower_clip: Update to the new load/store intrinsics - nir/lower_two_sided_color: Update to the new load intrinsic NIR and i965 changes are Reviewed-by: Kenneth Graunke <[email protected]> NIR indirect declarations and vc4 changes are Reviewed-by: Eric Anholt <[email protected]> ir3 changes are Reviewed-by: Rob Clark <[email protected]> NIR changes are Acked-by: Rob Clark <[email protected]>
