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

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.

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
• Include the llvm-mc tool in the distribution
• Update to wasi-libc 8b7148f69ae241a2749b3defe4606da8143b72e0
  • 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.

wasi-sdk-16

• Update to LLVM 14.0.4.
• Update wasi-libc to 30094b6ed05f19cee102115215863d185f2db4f0.
  • Fix utimensat to avoid passing uninitialized values into WASI calls.
  • Optimize memcpy etc. using bulk-memory
  • Update to musl 1.2.3.
  • Fix gettimeofday to correctly handle a null argument.
  • Remove support for __original_main. (#295)

wasi-sdk-15

Major updates include:

• Update to LLVM 14.0.
• Update to the latest wasi-libc
  • Add support for accept and accept4
  • Add support for DTTOIF and IFTODT.
  • Add support for utimes and futimesat.

wasi-sdk-14

wasi-sdk-13 accidentally included an older version of LLVM. This
release corrects the error, and fixes a packaging error on Windows.
