* nir: Separate texture from sampler in nir_tex_instrJason Ekstrand2016-02-091-0/+1
| | | | | | | | | | | | | This commit adds the capability to NIR to support separate textures and samplers. As it currently stands, glsl_to_nir only sets the texture deref and leaves the sampler deref alone as it did before and nir_lower_samplers assumes this. Backends can still assume that they are combined and only look at only at the texture index. Or, if they wish, they can assume that they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir all set both texture and sampler index whenever a sampler is required (the two indices are the same in this case).

* nir/tex_instr: Rename sampler to textureJason Ekstrand2016-02-091-4/+4
| | | | | | | | | We're about to separate the two concepts. When we do, the sampler will become optional. Doing a rename first makes the separation a bit more safe because drivers that depend on GLSL or TGSI behaviour will be fine to just use the texture index all the time.

* nir: Get rid of function overloadsJason Ekstrand2015-12-281-2/+1
| | | | | | | | | | | | | | | | | When Connor originally drafted NIR, he copied the same function+overload system that GLSL IR had with a few names changed. However, this double-indirection is not really needed and has only served to confuse people. Instead, let's just have functions which may not have unique names and may or may not have an implementation. If someone wants to do overload resolving, they can hav a hash table based function+overload system in the overload resolving pass. There's no good reason to keep it in core NIR.

* nir: Add a writemask to store intrinsics.Kenneth Graunke2015-12-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tessellation control shaders need to be careful when writing outputs. Because multiple threads can concurrently write the same output variables, we need to only write the exact components we were told. Traditionally, for sub-vector writes, we've read the whole vector, updated the temporary, and written the whole vector back. This breaks down with concurrent access. This patch prepares the way for a solution by adding a writemask field to store_var intrinsics, as well as the other store intrinsics. It then updates all produces to emit a writemask of "all channels enabled". It updates nir_lower_io to copy the writemask to output store intrinsics. Finally, it updates nir_lower_vars_to_ssa to handle partial writemasks by doing a read-modify-write cycle (which is safe, because local variables are specific to a single thread). This should have no functional change, since no one actually emits partial writemasks yet. v2: Make nir_validate momentarily assert that writemasks cover the complete value - we shouldn't have partial writemasks yet (requested by Jason Ekstrand). v3: Fix accidental SSBO change that arose from merge conflicts. v4: Don't try to handle writemasks in ir3_compiler_nir - my code for indirects was likely wrong, and TTN doesn't generate partial writemasks today anyway. Change them to asserts as requested by Rob Clark. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> [v3]

* nir: Get rid of *_indirect variants of input/output load/store intrinsicsJason Ekstrand2015-12-101-24/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]>

| | | | | | | | | | | | | | | | We want to start reworking and expanding this code, but it'll be a lot easier to do once we disentangle it from the rest of the stuff in nir.c. Unfortunately, there are a few unavoidable dependencies in nir.c on methods we'd rather not expose publicly, since if not used in very specific situations they can cause Bad Things (tm) to happen. Namely, we need to do some magical control flow munging when adding/removing jumps. In the future, we may disallow adding/removing jumps in nir_instr_insert_*() and nir_instr_remove(), and use separate functions that are part of the control flow modification code, but for now we expose them and put them in a separate, private header.
