Old Clang version in WASI SDK 13

[dasebek]

WASI SDK 12 came with clang version 11.0.0. WASI SDK 13 was released today, and it includes clang version 10.0.0. I downloaded and extracted wasi-sdk-13.0-linux.tar.gz from the releases page. I was expecting to see clang version 13.0.0 instead.

[david@fedora ~]$ /opt/wasi-sdk-12.0/bin/clang --version
clang version 11.0.0 (https://github.com/llvm/llvm-project 176249bd6732a8044d457092ed932768724a6f06)
Target: wasm32-unknown-wasi
Thread model: posix
InstalledDir: /opt/wasi-sdk-12.0/bin

[david@fedora ~]$ /opt/wasi-sdk-13.0/bin/clang --version
clang version 10.0.0 (https://github.com/llvm/llvm-project d32170dbd5b0d54436537b6b75beaf44324e0c28)
Target: wasm32-unknown-wasi
Thread model: posix

Hmm .. that does look wrong.

Note that WASI SDK versioning is independent of llvm/clang versioning so that fact that wasi-sdk-13 is supposed to contain llvm-13.0.0 is just a coincidence. It certainly shouldn't contain 10.0.0 though :(

[sbc100]

d32170dbd5b0d54436537b6b75beaf44324e0c28 is indeed the revision which is tagged as llvmorg-10.0.0 so this is not just clang being confused about which version it is.

I think that submodules under https://github.com/WebAssembly/wasi-sdk/tree/wasi-sdk-13/src point to wrong/old commit numbers.

It appears I made a mistake with git submodules and accidentally reverted the update to LLVM 13.0. I've now opened #204 to fix this. I'll plan to do a new wasi-sdk release once this is resolved.

#205 fixes the git submodules and fixes a Windows build issue. When the build artifacts from the build on main are ready, I'll create a new release.

Is a wasi-sdk-14.0-linux.tar.gz file coming? If that's the case I wait, in case it's not, how can I compile your sources? Just make? Any important make flag or env variable to be aware of? The install instructions in README.md are based on directly downloading the linux file.

[sunfishcode]

You can download the artifacts straight from the CI build if you'd like to download them now. These are the artifacts that I'll be attaching to the release once I sort out some minor issues around getting git-describe to output the right thing.

For example, on that page, click on dist-ubuntu-latest or dist-ubuntu-xenial to download a zip file containing the Linux wasi-sdk build.

[sunfishcode]

Ok, the artifacts are now attached to the wasi-sdk-14 release. Please let me know if there are any further problems!

Perfect! Thank you. I'm using the new build without any issue now :)
