* nir: Add a pass for gathering transform feedback infoJason Ekstrand2018-10-291-1/+3

* nir: Separate dead write removal into its own passCaio Marcelo de Oliveira Filho2018-10-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of doing this as part of the existing copy_prop_vars pass. Separation makes easier to expand the scope of both passes to be more than per-block. For copy propagation, the information about valid copies comes from previous instructions; while the dead write removal depends on information from later instructions ("have any instruction used this deref before overwrite it?"). Also change the tests to use this pass (instead of copy prop vars). Note that the disabled tests continue to fail, since the standalone pass is still per-block. v2: Remove entries from dynarray instead of marking items as deleted. Use foreach_reverse. (Caio) (all from Jason) Do not cache nir_deref_path. Not worthy for this patch. Clear unused writes when hitting a call instruction. Clean up enumeration of modes for barriers. Move metadata calls to the inner function. v3: For copies, use the vector length to calculate the mask. (all from Jason) Use nir_component_mask_t when applicable. Rename functions for clarity. Consider local vars used by a call to be conservative (SPIR-V has such cases). Comment and assert the assumption that stores and copies are always to a deref that ends with a vector or scalar.

* nir: Add an array copy optimizationJason Ekstrand2018-08-231-0/+1
| | | | | | | | | | | | This peephole optimization looks for a series of load/store_deref or copy_deref instructions that copy an array from one variable to another and turns it into a copy_deref that copies the entire array. The pattern it looks for is extremely specific but it's good enough to pick up on the input array copies in DXVK and should also be able to pick up the sequence generated by spirv_to_nir for a OpLoad of a large composite followed by OpStore. It can always be improved later if needed. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* nir: Add a structure splitting passJason Ekstrand2018-08-231-0/+1
| | | | | | | | | | | This pass doesn't really do much now because nir_lower_vars_to_ssa can already see through structures and considers them to be "split". This pass exists to help other passes more easily see through structure variables. If a back-end does implement arrays using scratch or indirects on registers, having more smaller arrays is likely to have better memory efficiency.

| | | | | | | | | | | | | | | | | | To simplify the transition, and make things bisectable, split out a legacy copy or lower_samplers. This way the i965 and gallium drivers can independently switch over to deref instructions. Since the lower_samplers_as_deref pass is only used by gallium drivers, it can be converted in lock-step with moving the lower_deref_instrs pass, and so does not need a corresponding _legacy clone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function will be the entry point for linking the uniforms from the nir_shader objects associated with the gl_linked_shaders of a program. This patch includes initial support for linking uniforms from NIR shaders. It is tailored for the ARB_gl_spirv needs, and it is far from complete, but it should handle most cases of uniforms, array uniforms, structs, samplers and images. There are some FIXMEs related to specific features that will be implemented in following patches, like atomic counters, UBOs and SSBOs. Also, note that ARB_gl_spirv makes mandatory explicit location for normal uniforms, so this code only handles uniforms with explicit location. But there are cases, like uniform atomic counters, that doesn't have a location from the OpenGL point of view (they have a binding), but that Mesa assign internally a location. That will be handled on following patches. A nir_linker.h file is also added. More NIR-linking related API will be added in subsequent patches and those will include stuff from Mesa, so reusing nir.h didn't seem a good idea. v2: move from compiler/nir to compiler/glsl (Timothy Arceri) v3: sets var->driver.location if the uniform was found from a previous stage (Neil Roberts).

* nir: mako all the intrinsicsRob Clark2018-03-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | I threatened to do this a long time ago.. I probably *should* have done it a long time ago when there where many fewer intrinsics. But the system of macro/#include magic for dealing with intrinsics is a bit annoying, and python has the nice property of optional fxn params, making it possible to define new intrinsics while ignoring parameters that are not applicable (and naming optional params). And not having to specify various array lengths explicitly is nice too. I think the end result makes it easier to add new intrinsics. v2: couple small fixes found with a test program to compare the old and new tables v3: misc comments, don't rely on capture=true for meson.build, get rid of system_values table to avoid return value of intrinsic() and *mostly* remove side-effects, add autotools build support v4: scons build Signed-off-by: Rob Clark <[email protected]> Acked-by: Dylan Baker <[email protected]> Acked-by: Jason Ekstrand <[email protected]>

* glsl: fix derived cs variablesIlia Mirkin2017-10-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are two issues with the current implementation. First, it relies on the layout(local_size_*) happening in the same shader as the main function, and secondly it doesn't work for variable group sizes. In both cases, the simplest fix is to move the setup of these derived values to a later time, similar to how the gl_VertexID workarounds are done. There already exist system values defined for both of the derived values, so we use them unconditionally, and lower them after linking is performed. While we're at it, we move to using gl_LocalGroupSizeARB instead of gl_WorkGroupSize for variable group sizes. Also the dead code elimination avoidance can be removed, since there can be situations where gl_LocalGroupSizeARB is needed but has not been inserted for the shader with main function. As a result, the lowering code has to insert its own copies of the system values if needed.
