Release version 9 with snapshot1 version libc.

[sbc100]

Are we ready to do this?

[pchickey]

I'd like to attempt to use the artifacts built on Actions for the release, so lets merge #83 and then go for it

[pchickey]

Actually, lets try to resolve WebAssembly/wasi-libc#146 first. I'll tag @sunfishcode to give his input on that one, I am not familiar with that sort of CPP stuff.

[sunfishcode]

WebAssembly/wasi-libc#148 has a fix.

[pchickey]

Hmm, this got lost in all of our other tasks, I think. Is there anything blocking cutting release 9 right now? If not, I'll take care of doing the release.

Heres the outstanding PRs:

• [ ] wasi-sdk support for full LTO. #89 is approved but based on an out-of-date wasi-libc. needs rebase.
• Add beginner-level documentation for installation and use #107 appears ready, awaiting sign-off by @sunfishcode
• Strip symbols of all binaries #109 appears ready, awaiting sign-off by @sunfishcode
• latest wasi-libc (NFC) #113 I just opened to bump to the very latest wasi-libc, which only has a readme change, so no effect to this repo

[pchickey]

Additionally, WebAssembly/wasi-libc#188 fixes a regression from the last release (utime.h was present, this breaks at least one test in lucet) so lets get that one in if we reasonably can

[sunfishcode]

#89 should be coordinated with WebAssembly/wasi-libc#150, which isn't quite ready to go yet. It's fine to leave it out for this release.

The rest of the PRs are now merged.

[pchickey]

Thanks very much for getting to all of these PRs! Lets leave LTO out of the release, then.

I'm about to call it a week at work, hopefully we can figure out what Mac CI stuff is going wrong and cut the release on Monday.

I tagged the release and uploaded built artifacts for linux and mac: https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-9

I'll write up release notes tomorrow
