It seems emscripten doesn't have errqueue.h so removed sock_extended_err from emscripten: https://github.com/emscripten-core/emscripten/tree/master/system/include/libc

It seems emscripten doesn't have IPV6_FLOWINFO: https://github.com/emscripten-core/emscripten/blob/2bca083cbbd5a4133db61fbd74d04f7feecfa907/system/include/libc/netinet/in.h#L312-L337
TCP_FASTOPEN_CONNECT is also missing.
The remaining constraints are in errqueue.h.

So, I think all items can be removed from emscripten.

JohnTitor · 2020-04-12T17:28:12Z

Seems the definition of pthread_mutexattr_t was removed in this commit: emscripten-core/emscripten@953e414
But I couldn't find any related change to pthread_condattr_t. So I'd skip it for now and add FIXME to unblock the progress.

JohnTitor · 2020-04-12T23:21:13Z

The errnos were changed in emscripten-core/emscripten@09e9050.
Also somehow max_align_t was changed, I suspect the cause is emscripten-core/emscripten#10145

JohnTitor · 2020-04-13T00:24:11Z

Finally, CI is green!
r? @alexcrichton could you review if the things are correct?

bors · 2020-04-13T14:10:39Z

☔ The latest upstream changes (presumably #1719) made this pull request unmergeable. Please resolve the merge conflicts.

alexcrichton · 2020-04-13T14:52:35Z

I don't know a ton about this target myself, but it seems reasonable enough to me.

JohnTitor · 2020-04-13T22:38:23Z

Thanks, I think you're familiar with that than me :) Then I'm going to merge this, hopefully, there's no breakage.

Re-enable CI for `asmjs-unknown-emscripten` #1591 was closed by #1697 but it was only for `wasm32-unknown-emscripten` actually. We should make a new issue and link to it instead if it's still broken. r? `@ghost`
