Detailed Description
Opaque handle types for the CppInterOp C and C++ API.
Each handle wraps a single void* and is a distinct type so the compiler rejects cross-kind misuse (e.g. passing a TypeRef where a DeclRef is expected). Layout is identical across all handles — a single pointer — so they are trivially copyable and ABI-stable.
The C and C++ views are declared independently:
- C sees
struct CppDeclRef { void* data; }etc. at global scope, prefixed so they don't collide with generic names from other C libraries. - C++ sees
Cpp::DeclRefetc. in namespaceCpp, no prefix — the namespace already disambiguates. Both have identical layout, so a C-linkage function exchanging these structs across the boundary is byte-identical regardless of which view names it. The TableGen-emitted C-API .inc adds C++ typedef aliases (using CppDeclRef = Cpp::DeclRef;) so the generated C wrappers compile under C++ using the prefixed C-side names.
