2023-07-03Refactor "meta" decls for stdlib texture types (#2932)Theresa Foley
We use some ad-hoc "template engine" code generation / metaprogramming to generate many of the declarations in the Slang standard library. In many cases the level of meta-ness is (relatively) manageable, but one of the biggest tangles in the whole thing is the generation of the texture-related types. We basically have a single set of nested `for` loops that generate all types of the form: (RW|RasterizerOrdered|/**/)(Texture|Sampler)(1D|2D|...)Array?MS? Inside that loop we then have tons of conditional logic to determine: * Which points in the cross-product space should be skipped, rather than emitted as a type. * Which methods to emit, or not. * The type signature(s) of those methods. * The translation of those methods for each target (via `__target_intrinsic`) The code ends up being long, complicated, and very hard to maintain or extend. This change takes a first small step to try to help us get the complexity more under control. The basic approach is that the data that defines each point in the cross-product space is aggregated into a `TextureTypeInfo` structure in the meta-level code, and then the logic for emitting the declarations related to a given texture type is expressed as a member function of that type. The intention is that this design will more easily allow the meta-level code to be factored into distinct subroutines, and enable us to clean up and re-use recurring bits of text that need to appear in the output. It is possible (though I am not yet predicting it) that we will end up wanting to utilize a bit of an inheritance hierarchy on `TextureTypeInfo` to allow us to more cleanly factor out code that is specific to certain cases (e.g., there is only a small amount of sharing between `RW`/`RasterizerOrdered` and read-only texture types). It is intentional that this step introduces no significant changes to the logic that used to be inside the loop (and is now inside of a method). Instead, the goal is to minimize the scale of the diffs that reviewers might be expectecd to deal with in follow-on changes. Co-authored-by: Yong He <yonghe@outlook.com>
