This document tries to capture and document the named annotations to provide a reference for future contributors. Reviewed By: python3kgae Differential Revision: https://reviews.llvm.org/D134304

Introduction
|
|
============
|
|
|
|
The goal of this document is to provide a reference for all the special purpose
|
|
IR metadata and attributes used by the HLSL code generation path.
|
|
|
|
IR Metadata
|
|
===========
|
|
|
|
``hlsl.uavs``
|
|
-------------
|
|
|
|
The ``hlsl.uavs`` metadata is a list of all the external global variables that
|
|
represent UAV resources.
|
|
|
|
Function Attributes
|
|
===================
|
|
|
|
``hlsl.shader``
|
|
---------------
|
|
|
|
The ``hlsl.shader`` function attribute is a string attribute applied to entry
|
