[PATCH] D64537: [WebAssembly] Implement thread-local storage (local-exec model)

[Guanzhong Chen via Phabricator via cfe-commits]

quantum added a comment.

@sbc100 As for `__tls_base` being immutable, I am not sure how this will interact with dynamic linking once we implement it. On native platforms, `dlopen`ed libraries have their TLS blocks allocated on first use.

What exactly happens to `dlopen`ed libraries when there are already threads around? Would it be feasible to create TLS blocks for when the library is loaded on existing thread?
