[PATCH] D66035: [WebAssembly] WIP: Add support for reference types

Mon Oct 7 13:28:14 PDT 2019

tlively added a comment.

Another approach to reference types we should look at is clang's upcoming sizeless types support (https://reviews.llvm.org/D62962, RFC: http://lists.llvm.org/pipermail/cfe-dev/2019-June/062523.html). This would allow reference types to be constructed at the source level but most operations such as `sizeof`, loading, and storing would be disallowed because they would be treated as incomplete types.

I don't think that approach is inconsistent with this one, though. This patch deals mostly with the backend while sizeless types are a frontend concept. I'm not sure what the codegen and lowering would look like, though.
