Forked ILGPU

Modified fork of ILGPU, included as private asset reference. Modifying internals (e.g., internal → public, adding intrinsics) is expected and preferred over workarounds.

T4 Templates — CRITICAL

Many .cs files are generated from .tt templates. Before editing any .cs file, check for a matching .tt file. Edits to generated files are silently overwritten on rebuild.

Cross-Backend Impact

Changes here affect ALL 6 backends (CUDA, OpenCL, CPU, WebGPU, WebGL, Wasm). Consider all of them before modifying.

Key Areas

  • IR/Types/StructureType.cs — struct type flattening, DirectFields vs Fields (flattened), GetOffset()
  • IR/Values/ — IR value types (GetField, Store, GenericAtomic, Barrier, etc.)
  • Runtime/Accelerator.cs — AcceleratorType enum (includes .Wasm)
  • Runtime/MemoryBuffer.cs — NativePtr (public setter for Wasm dispatch patching)
  • Runtime/ArrayView*.cs — ArrayView, ArrayView1D struct layouts
  • Stride.cs, StrideTypes.cs — stride definitions (Dense has no instance fields)

ILGPU IR Type System Quick Reference

  • AddressSpaceType — pointer/view type (ArrayView lowers to this)
  • StructureType — flattened struct. DirectFields = top-level fields. Fields = all leaf fields.
  • PrimitiveType — Int32, Int64, Float32, Float64, etc.
  • StructureType.Builder.Add() recursively flattens nested structs (line ~128)
  • StructureType.GetOffset(FieldAccess) returns byte offset of leaf field
