[SPIR-V] Support arrays of RW/append/consume structured buffers #3164

Closed mattruschnv closed 1 year ago

mattruschnv commented 3 years ago

Currently I'm trying to port a shader which uses the following to Vulkan: RWStructuredBuffer VisTLASInstances[] : register(u0, space3);

It would be awesome if this were supported for spirv as well as dxil.

@mattruschnv thank you for reporting this issue. First of all, we want to understand exactly what you want. Could you please share a full shader that I can compile?

In addition, if this is not supported for DXIL, then I recommend you not specifying it as "SPIRV" issue. If it is in that case, we need a dicussion with DXIL developers to understand what we are missing (I guess probably AST parser does not support it) and it is possible (or reasonable) to support it.

To clarify, it IS supported for DXIL.

We'd very much like to see support for this too to enable a bindless model for RWStructuredBuffers in vulkan as well as dx.

With will be handled under #5440. I want all of the issues in a central place with a fresh conversation.
