This updates to include WebAssembly/wasi-libc#709 and then additionally
configures wasi-libc with `-DWASI_SDK_VERSION=...` to ensure that
wasi-sdk builds will now have `__wasi_sdk_major__` defined along with
`__wasi_sdk_version__`.
ClosesWebAssembly/wasi-libc#688
This commit updates the build of the `wasm32-wasip2` target to always
pass `-fPIC` to compilation of wasi-libc. This notably enables using
`libc.a` in dynamic linking situations instead of being forced to use
`libc.so`. While many applications likely want to use `libc.so` I've
found it more flexible if objects are compatible with as many builds as
possible. This will enable, for example, building shared libraries in
Rust by default since Rust only ships `libc.a`, not `libc.so`, in the
pre-built sysroot. This behavior additionally matches the Rust
`wasm32-wasip2` target where `-fPIC` is enabled by default there.
This commit enables thread support in libc++ for all thread models,
enabling C++ applications that use threading APIs like `<atomic>` but do
not spawn threads (e.g. Clang) to be built with minimal changes.
Fixes#546.
Depends on WebAssembly/wasi-libc#602.
Update from LLVM 20.1.1 to 20.1.8. This release contains various bug
fixes and notably for wasi-sdk includes llvm/llvm-project#146574, which
fixes inline asm vector operands.
* Update to the latest wasi-libc.
This contains two significant changes:
- Implement a stub pthreads library for `THREAD_MODEL=single` (#518)
- Initial FTS support (#522)
* Update to the latest wasi-libc with build fix
This update includes a build fix for shared library builds.

To include https://github.com/WebAssembly/wasi-libc/pull/517,
which is necessary to avoid modifying host compiler's resource
directory.
At least on my environment (macOS if it matters), without the above
mentioned fix, gmake tries to create the directory for wasi compiler-rt
during wasi-libc build. I'm not sure why it didn't happen for others.
cf. https://github.com/WebAssembly/wasi-sdk/pull/445
* Add LTO build of wasi-libc
* Add LTO build of libc++
* Update wasi-libc (to include the LTO support)
* Add a comment about /llvm-lto/${llvm_version} convention
* Use separate targets for wasi-libc with and without lto
A downside: this makes four more copies of wasi-libc source tree.
* Make LTO build optional
* Add DWARF debugging information to all artifacts by default
This commit adds DWARF debugging information with the `-g` compiler flag
to all WASI artifacts for wasi-sdk. The LLVM build itself does not have
debugging information, only the sysroot artifacts. This is intended to
assist with debugging. The main downside to this is binary size of
generated artifacts will, by default, be larger. Stripping debug
information from an artifact though involves removing custom sections
which is generally pretty easy to do through wasm tooling.
* Pass extra cflags to wasi-libc
* Fix tests from previous commit
* Update some expected error messages and remove some files with
duplicate error messages that are no longer needed.
* Remove undefined behavior in `stat.c` where padding bytes were being
compared.
* Update LLVM to 18.1.2 and add wasm-component-ld
This commit has two intertwined changes within it. First the LLVM
submodule is updated to the 18.1.2 release branch. This alone would
cause CI and tests to fail due to differing behavior for the
`wasm32-wasip2` target. To fix these test failures the
`wasm-component-ld` tool is added to the build. This tool is a
Rust-written tool and installed via `cargo install` as part of the build
at a pinned version written in the `Makefile`. This linker, used for
components, is then used for the `wasm32-wasip2` target.
Tests and CI are then updated to skip the need to have `wasm-tools` or
the adapter for WASI when making components since that's now the job of
`wasm-component-ld`. This then necessitated some changes to tests too.
* Add back accidentally deleted CI
* Inherit tools on PATH on Windows
* Add Rust to docker build
* Put rust in a different location in docker
* Try to fix permissions
* Review comments
* Revert changes to test outputs
This updates the `wasi-libc` submodule to point to `main` and also:
- update tests/testcase.sh to use new wasm32-wasip2 target name
- update various tests/**/*.expected files to match Wasmtime output

* Explicitly set LIBCXXABI_USE_LLVM_UNWINDER off
Clang trunk has recently turned it on, and also now fails the build when
libunwind is not built at the same time.
* Bump LLVM to 18.1.0

* Start renaming preview1 to p1 and preview2 to p2
This commit is a reflection of WebAssembly/wasi-libc#478 into this
repository where a few changes are happening:
* A new `wasm32-wasip1` sysroot is prepared matching `wasm32-wasi`
* A new `wasm32-wasip1-threads` sysroot is prepared matching `wasm32-wasi-threads`
* The `wasm32-wasi-preview2` target is renamed `wasm32-wasip2`
I've done a bit of makefile refactoring to deduplicate things a bit now
that there's a number of targets being built.
The long-term goal would be to remove the `wasm32-wasi` and
`wasm32-wasip1-threads` targets, but that's not proposed just yet at
this time.
* Use $(CLANG_VERSION) instead of hardcoding
As of LLVM 17, which includes https://reviews.llvm.org/D152168, libcxx has
combined the old `_LIBCPP_HAS_NO_FILESYSTEM_LIBRARY` and
`_LIBCPP_HAS_NO_FSTREAM` preprocessor symbols into a single
`_LIBCPP_HAS_NO_FILESYSTEM` symbol, which means there's no longer any way to
enable `<fstream>` without enabling `<filesystem>`.
The solution is to set `-DLIBCXX_ENABLE_FILESYSTEM:BOOL=ON` and update
`wasi-libc`, which includes stubs for the functions required by libcxx's
`<filesystem>` implementation.

* build and test `wasm32-wasi-preview2` target
This updates `wasi-libc` to include
https://github.com/WebAssembly/wasi-libc/pull/457, which adds preliminary
support for the new `wasm32-wasi-preview2` target.
It also adds support for testing the new target using Wasmtime 16.0.0 and
`wit-component`. Note that Wasmtime produces different output when reporting
errors for Preview 2 components than it does for Preview 1 modules, so I've
added a few .expected files specific to Preview 2.

WebAssembly/wasi-libc#403 fixed an issue with `a_barrier` that should be
included in the next release of wasi-sdk. This change updates wasi-libc
to the latest `HEAD` of `main` to include it.
* llvm-project: update to 16.0.0 release
This changes updates the `src/llvm-project` submodule to the `HEAD` of
`release/16.x`, the same commit used to [release] the LLVM 16.0.0
binaries.
[release]: https://github.com/llvm/llvm-project/releases/tag/llvmorg-16.0.0
* fix: use only Clang's major version in install prefix
Due to [a change] in LLVM, Clang will expect to find the
`libclang_rt.builtins-wasm32.a` file in a path that only contains the
major version (`16`) instead of the entire version (`16.0.0`) as was
previously the case. This change modifies the `CMAKE_INSTALL_PREFIX` to
use Clang's major version only.
[a change]: https://reviews.llvm.org/D125860
* review: only use `llvm_version_major.sh`
Since the `Makefile` can get by with only knowing Clang's major version,
this change removes `llvm_version.sh` and sets `CLANG_VERSION` to use
only the major part.
* Update wasi-libc to latest HEAD
This pulls in a variety of changes, many of them related to enabling
threads in wasi-libc. There may be more changes necessary before
releasing a prelease version of wasi-sdk that supports the new
`wasm32-wasi-threads` target, but this should get the majority of them.
* review: incorporate WebAssembly/wasi-libc#324
* Update llvm-project to the latest release/15.x
This pulls in the `__heap_end` symbol, which fixes the issue discussed
in https://github.com/WebAssembly/wasi-libc/pull/377.
* Update to the official 15.0.7 release.
