Full Changelog: wasi-sdk-20...wasi-sdk-21

wasi-sdk-20

This release largely consists of changes in two directions: a) wasi-sdk now is built upon LLVM 16 and b) it includes experimental support for the wasm32-wasi-threads target. Note that wasm32-wasi-threads is much less stable than the default target, wasm32-wasi; since the wasi-sdk-20+threads pre-release, wasm32-wasi-threads has received several fixes and improvements, but use at your own risk.

What's Changed

• Only push docker image on push or tag by @anuraaga in #288
• add experimenal wasm32-wasi-threads support by @yamt in #274
• Update wasi-libc to latest HEAD by @abrown in #290
• ci: document and script the release process by @abrown in #295
• Get arch from system when building debian package by @johalun in #298
• Build libcxxabi and libcxx with threads enabled by @whitequark in #301
• download-workflow-artifacts.sh: skip dist-ubuntu-latest by @yamt in #307
• Downgrade OSX deployment target to 10.12 by @abrown in #308
• wasi-libc: upgrade to latest main branch by @abrown in #313
• llvm: update to LLVM 16.0.0 by @abrown in #314
• Force clang as CMake Assembly compiler, with wasm32-wasi triple by @directhex in #315
• Update docker build to use LLVM 16 by @anuraaga in #316
• wasi-libc: update to include atomic barrier fix by @abrown in #317

New Contributors

• @johalun made their first contribution in #298
• @whitequark made their first contribution in #301

wasi-sdk-20+threads

This is a pre-release of the wasm32-wasi-threads target support plus
LLVM 16rc2 . WARNING: this pre-release is experimental and does not
guarantee future ABI stability!

What's Changed

• Only push docker image on push or tag by @anuraaga in #288
• add experimenal wasm32-wasi-threads support by @yamt in #274
• Update wasi-libc to latest HEAD by @abrown in #290

wasi-sdk-19

wasi-sdk-19

• Specify CMAKE_OSX_DEPLOYMENT_TARGET when building llvm (#285)
• Update llvm-project to the latest release/15.x (#286)
• Add README section for docker image (#282)

Note to users using -Wl,--initial-memory= and using the wasi-sysroot here with their own clang rather than using the clang provided here: This wasi-sysroot's wasi-libc's malloc implementation will not be able to use the full memory made available by -Wl,--initial-memory= unless it is linked with a wasm-ld from LLVM 15.0.7 or later.
