* glsl: serialize data from glTransformFeedbackVaryingsTapani Pälli2018-06-261-0/+20
| | | | | | | | | | While XFB has been enabled for cache, we did not serialize enough data for the whole API to work (such as glGetProgramiv).

| | | | | | | | | | | | | System values are never arrays or structs so we can assume a direct var deref. This simplifies things a bit and prevents us from accidentally throwing away an array index.

| | | | | | | | | | | | | | | | | | 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 legacy pass will be removed in a future commit.

* nir,spirv: Rework function callsJason Ekstrand2018-06-2216-534/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit completely reworks function calls in NIR. Instead of having a set of variables for the parameters and return value, nir_call_instr now has simply has a number of sources which get mapped to load_param intrinsics inside the functions. It's up to the client API to build an ABI on top of that. In SPIR-V, out parameters are handled by passing the result of a deref through as an SSA value and storing to it. This virtue of this approach can be seen by how much it allows us to delete from core NIR. In particular, nir_inline_functions gets halved and goes from a fairly difficult pass to understand in detail to almost trivial. It also simplifies spirv_to_nir somewhat because NIR functions never were a good fit for SPIR-V. Unfortunately, there is no good way to do this without a mega-commit. Core NIR and SPIR-V have to be changed at the same time. This also requires changes to anv and radv because nir_inline_functions couldn't handle deref instructions before this change and can't work without them after this change.

* spirv: Allow pointers to have a deref at the baseJason Ekstrand2018-06-222-43/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, pointers fell into two categories: index/offset for UBOs, SSBOs, etc. and var + access chain for logical pointers. This commit adds another logical pointer mode that's deref + access chain. It's tempting to think that we can just replace variable-based pointers with deref-based or at least replace the access chain with a deref chain. Unfortunately, there are a few sticky bits that prevent this: 1) We can't return deref-based pointers from OpVariable because those opcodes may come outside of a function so there's no place to emit the deref instructions. 2) We can't always use variable-based pointers because we may not always know the variable. (We do now, but he upcoming function rework will take that option away.) 3) We also can't replace the access chain struct with a deref. Due to the re-ordering we do in order to handle loop continues, the derefs we would emit as part of OpAccessChain may not dominate their uses. We normally fix this up with nir_repair_ssa but that generates phi nodes which we don't want in the middle of our deref chains. All in all, we have no real better option than to support partial access chains while also re-emitting the deref instructions on the spot.

* spirv: Make push constants an offset-based pointerJason Ekstrand2018-06-222-28/+17
| | | | | | | | | | | | | | | | | | Push constants have been a weird edge-case for a while in that they have explitic offsets but we've been internally building access chains for them. This mostly works but it means that passing pointers to push constants through as function arguments is broken. The easy thing to do for now is to just treat them like UBOs or SSBOs only without a block index. This does loose a bit of information since we no longer have an accurate access range and any indirect access will look like it could read the whole block. Unfortunately, there's not much we can do about that. Once NIR derefs get a bit more powerful, we can plumb these through as derefs and be able to reason about them again.
