Description

In HLSL parameter passing is copy-in/copy-out as specified by the in, inout and out parameter modifier keywords.

A proposal for how this will be implemented is documented in the Clang HLSL docs.

Deliverable

A full implementation of the solution in the document above and any required updates to the document.

Acceptance Criteria

  • Documentation reflects the implementation
  • Implementation is fully tested with codegen tests for DXIL and SPIR-V code generation.
