* Pointer layout support (#2930)jsmall-nvidia2023-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * WIP looking at reflection with pointers. * Added GetPointerLayout. * Initial test via reflection with layout of ptr type. * WIP handles ptrs to types that have layout that hasn't been completed. * Move tests to ptr. * WIP try to take into account lowering correctly between AggTypeDecl and Type, but doesn't quite work. * WIP a different path to handling recursive lowering problem with Ptr. * Fix issues with reflection output. * Small tidy. * Fix for infinite recursion issue. * Lower IRPointerTypeLayout * Working with generics. Has a hack to work around Layout around Ptr in IR. The reflection around the generic - the name isn't much use, it should probably have the generic parameters, but that would require getName to do something more sophisticated. * Fix issue around calling finishOuterGenerics to early. * Remove feature/ptr test. * Fix type legalization being an infinite loop with Ptr self referencing. * Disable the pointer self reference test because produces an infintie loop on emit. * Fixed comment based on review. * Fix for issue with emit and pointers causing infinite recursion.
* fixed incorrect handling of D3D12_RENDER_TARGET_VIEW_DESC.ViewDimensi… (#2897)kopaka18222023-05-23
| | | | | | | | | | * fixed incorrect handling of D3D12_RENDER_TARGET_VIEW_DESC.ViewDimension for arrays (needs to be set based on the underlying resource and not the requested view. Otherwise members like FirstArraySlice can not be set properly). Also fixes problems with D3D12_RENDER_TARGET_VIEW_DESC.PlaneSlice since Texture2DArray.PlaneSlice and Texture2D.PlaneSlice do not share the same memory location (unlike the MipSlice). * fixed isArray definition for d3d12 texture views --------- Co-authored-by: Yong He <yonghe@outlook.com>
