Create a separate sysroot for coop threads - #647
Merged
Conversation
This commit creates a separate sysroot for coop threads for the `wasm32-wasip3` target. This is explicitly labeled with `experimental` in the name and isn't passed anywhere by default. The intention is to assist with testing of this sysroot by making it reasonably easy to use it and test that everything works. Using it requires passing `--sysroot` to the folder generated here, and a simple "hello world" with threads completes locally. This necessitated a minor update to an LLVM patch which reflects the updated state of a PR upstream.
