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

[Derek Schuff via Phabricator via cfe-commits]

dschuff added a comment.

The `offset` field of a segment can be a constant expression <https://webassembly.github.io/spec/core/valid/instructions.html#constant-expressions> which can be a `global.get` of an imported global. So we could have an imported global `__tls_base` which is different for each thread, and have an active segment with that as its segment offset?
