* nir/remove_dead_variables: Properly handle deref castsJason Ekstrand2019-01-081-0/+3
| | | | | | | | | | We already detect any incomplete deref chains (where the deref is used for something other than another deref or a load/store) and flag the variable as used thanks to deref_used_for_not_store. All that's left to do is to properly skip casts when cleaning up. Reviewed-by: Alejandro Piñeiro <[email protected]> Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* nir/deref: Skip over casts in fixup_deref_modesJason Ekstrand2019-01-081-0/+2
| | | | | | | | | | This pass is used when, for instance, we lazily change the mode of variables rather than replacing the variable with a new one. Since we only do this in cases where we know we have full deref chains, it's ok to just skip them in fixup_deref_modes.

* nir/deref: Support casts and ptr_as_array in comparisonsJason Ekstrand2019-01-081-7/+68
| | | | | | | | | | | | The code which constructs deref paths already gives you the path starting at the nearest deref_cast or deref_var. All we need to do for casts is handle the case where the start of the path isn't a deref_var. For ptr_as_array derefs, we just bail if we have any after the divergence point between the two derefs. We may be able to do better in the future but this works for now. Reviewed-by: Alejandro Piñeiro <[email protected]> Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* nir/opt_deref: Properly optimize ptr_as_array derefsJason Ekstrand2019-01-081-6/+91
| | | | | | | | | | | | | | When handling casts, we can't blindly propagate the parent of a cast into a ptr_as_array deref because doing so might loose the stride information from the cast. Instead, before we can propagate into ptr_as_array derefs, we need to check that the cast is a cast of an array deref and that the stride matches. For other types of derefs, we can continue to propagate casts as normal because they don't need the stride. We also add an optimization which can combine a ptr_as_array deref with it parent if it is also an array deref of some form.

* nir: Add a ptr_as_array deref typeJason Ekstrand2019-01-0812-13/+106
| | | | | | | | | | | | | | These correspond directly to SPIR-V's OpPtrAccessChain. As such, they treat whatever their parent gives them as if it's the first element in some array and dereferences that array. If the parent is, itself, an array deref, then the two indices can just be added together to get the final array deref. However, it can also be used in cases where what you have is a dereference to some random vec2 value somewhere. In this case, we require a cast before the ptr_as_array and use the ptr_stride field in the cast to provide a stride for the ptr_as_array derefs.

* spirv: Propagate layout decorations to created glsl_typesJason Ekstrand2019-01-083-14/+78
| | | | | | | | | | | | | | | Instead of just storing the decorations in the vtn_type, propagate them all the way through to the glsl_type. For array strides, this means we need to handle them earlier so we break array stride handling into it's own function and explicitly call it for both pointer and array types. Due to type deduplication in the SPIR-V, we may have explicit layout decorations on all sorts of types that don't actually want them. In order to prevent these leaking into unfortunate places in NIR, we explicitly strip them off before creating NIR variables and when casting pointers to non-external memory.

* glsl_type: Add support for explicitly laid out matrices and arraysJason Ekstrand2019-01-0815-56/+258
| | | | | | | | | | | | | | | | | | | | | | SPIR-V allows for matrix and array types to be decorated with explicit byte stride decorations and matrix types to be decorated row- or column-major. This commit adds support to glsl_type to encode this information. Because this doesn't work nicely with std430 and std140 alignments, we add asserts to ensure that we don't use any of the std430 or std140 layout functions with explicitly laid out types. In SPIR-V, the layout information for matrices is applied to the parent struct member instead of to the matrix type itself. However, this is gets rather clumsy when you're walking derefs trying to compute offsets because, the moment you hit a matrix, you have to crawl back the deref chain and find the struct. Instead, we take the same path here as we've taken in spirv_to_nir and put the decorations on the matrix type itself. This also subtly adds support for strided vector types. These don't come up in SPIR-V directly but you can get one as the result of taking a column from a row-major matrix or a row from a column-major matrix.

* nir: Distinguish between normal uniforms and UBOsJason Ekstrand2019-01-0813-38/+44
| | | | | | | | | | | | | | | | Previously, NIR had a single nir_var_uniform mode used for atomic counters, UBOs, samplers, images, and normal uniforms. This commit splits this into nir_var_uniform and nir_var_ubo where nir_var_uniform is still a bit of a catch-all but the nir_var_ubo is specific to UBOs. While we're at it, we also rename shader_storage to ssbo to follow the convention. We need this so that we can distinguish between normal uniforms and UBO access at the deref level without going all the way back variable and seeing if it has an interface type.

* spirv: Emit NIR deref instructions on-the-flyJason Ekstrand2019-01-083-71/+34
| | | | | | | | | | | | | | | This simplifies our deref handling by emitting the actual NIR deref instructions on-the-fly instead of of building up a deref chain and then emitting them at the last moment. In order for this to work with the parts of the compiler that assume they can chase deref chains, we have to run nir_rematerialize_derefs_in_use_blocks_impl to put the derefs back in the right places. Otherwise, in cases such as loop continues where the SPIR-V blocks are not in the same order as the NIR blocks, we may end up with a deref chain with a parent that does not dominate it's child and nir_repair_ssa_impl will insert phis in the deref chain.

* nir: Make gl_nir_lower_samplers use gl_nir_lower_samplers_as_derefKenneth Graunke2019-01-071-47/+28
| | | | | | | | | | | | | | | | | | | | | | | | These days, we have two sampler lowering passes. The newer one, gl_nir_lower_samplers_as_deref, is used by radeonsi. It rewrites variables to drop structures out of sampler deref chains, to make life simpler. It then sets var->data.binding for non-bindless sampler and image variables based on the GL uniform storage's opaque index values. The older one converts sampler deref chains (nir_tex_src_texture_deref) to a numerical offset (nir_tex_src_texture_offset). It also stores the constant-valued portion of that number in tex->texture_index, making life really simple for drivers that don't support indirects. It too pokes at GL uniform storage's opaque index values. Logically, we can do the first pass (simplify derefs, set bindings) then the second (turn derefs to offsets, set texture_index). This patch does exactly that, eliminating some redundancy (only one pass has to poke at GL uniform storage), and gaining proper var->data.binding values for drivers using the full lowering.

* nir: Fix gl_nir_lower_samplers_as_deref's structure type handling.Kenneth Graunke2019-01-071-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | We recurse to remove structures, and at each step, re-modify the resulting type for our link in the deref chain. For arrays, the result of recursion is the new underlying type - so we wrap it with the array dimensionality again. For structs, we want to simply use the new underlying type, skipping the struct altogether. The correct way to do this is to do nothing at all. Previously, we had reset type to next->type, which is the /old/ field type, not the new field type we obtained by recursing. This undid our recursive work. Fixes about 338 tests with nested structs, such as: dEQP-GLES2.functional.uniform_api.value.initial.get_uniform.nested_structs_arrays.sampler2D_samplerCube_fragment Note that currently only radeonsi uses this pass, and NIR support is disabled there by default, so the breakage was likely not seen by most people.
