[PATCH] D139010: [clang][WebAssembly] Implement support for table types and builtins

[Thomas Lively via Phabricator via cfe-commits]

tlively added a comment.

It looks like the LLVM-side changes are generally moving Wasm type classification functions to a more global location. Since no other backend should care about these things, it would be better if we could get away without these changes.



================
Comment at: llvm/include/llvm/IR/Type.h:23
 #include "llvm/Support/TypeSize.h"
+#include "llvm/CodeGen/WasmAddressSpaces.h"
 #include <cassert>
----------------
I don't know if things in IR are supposed to depend on things in CodeGen. Is there precedent here?


================
Comment at: llvm/include/llvm/IR/Type.h:220-232
+  bool isWebAssemblyReferenceType() const { return isWebAssemblyExternrefType() || isWebAssemblyFuncrefType(); }
+
+  /// Return true if this is a WebAssembly Externref Type.
+  bool isWebAssemblyExternrefType() const {
+    return getPointerAddressSpace() ==
+             WebAssembly::WasmAddressSpace::WASM_ADDRESS_SPACE_EXTERNREF;
+  }
----------------
Do these need to be in Type.h? If not, it would be good to keep them in a more Wasm-specific location.
