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

Full Changelog: wasi-sdk-19...wasi-sdk-20+threads

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.

wasi-sdk-18

• Build macOS universal binaries (#270)

• Update to the latest wasi-libc (#283)

  • Don't use sbrk(0) to determine the initial heap size (WebAssembly/wasi-libc#377)
  • Fix more headers to avoid depending on max_align_t (WebAssembly/wasi-libc#375)
  • Use ENOENT rather than ENOTCAPABLE for missing preopens. (WebAssembly/wasi-libc#370)
  • Adjust Makefile for LLVM trunk (16) as of 2022-11-08 (WebAssembly/wasi-libc#344)

NOTE: This release changes the behavior of malloc in programs compiled with -Wl,--initial-memory to use memory.grow rather than using all the statically-allocated memory. This will be fixed in wasi-sdk-19.

wasi-sdk-17

wasi-sdk-17

• Update to LLVM 15.0.6

  • The major change in this version is that static constructors are no
    longer run on user exports.
    (WebAssembly/wasi-libc#328)
  • Add an __errno_location function, which returns the
    address of errno, making it easier to bind to from languages
    without direct TLS access.
  • Change readdir to call fstatat if d_ino is 0.
    (WebAssembly/wasi-libc#345)
  • Support -fstack-protector.
