Update: progress slow on the PR. Right now I’m testing changes to address feedback. Then I’m going to rebase to incorporate the nodejs detection from https://github.com/rust-lang/rust/pull/36256. Then merge. There are two major issues with asmjs/wasm support:
- When enabling asmjs/wasm, jemalloc is disabled for all targets. This must be fixed before we can create nightlies. This would be a useful thing for somebody to look into. I don’t see myself doing it today.
- Unwinding of course is busted. Good thing for somebody to look into. I probably won’t be able to prioritize this myself for a long time. A possible approach here is to add an unwinder implementation that targets libcxxabi (which emscripten does support) instead of targeting libunwind directly.
