It's not generally needed. It was added in
https://github.com/tinygo-org/tinygo/pull/3958 to fix an issue with
binaryen that has since been fixed in a different way, so we don't need
the googletest dependency anymore.
Node.js 16 is no longer supported, so we can drop support for it as
well.
This also means updating a whole lot of GitHub Actions versions, because
they were updated to work on Node.js 20 instead. For most actions this
should be a relatively small change, but the upload-aftifact action has
had some major changes (which should generally improve things a lot).
This means we can finally release native arm64 builds of TinyGo on
macOS!
Also update from macOS 11 to macOS 12, because macOS 11 is not supported
anymore.
This adds a flake.nix file that makes it possible to quickly create a
development environment.
You can download Nix here, for use on your Linux or macOS system:
https://nixos.org/download.html
After you have installed Nix, you can enter the development environment
as follows:
nix develop
This drops you into a bash shell, where you can install TinyGo simply
using the following command:
go install
That's all! Assuming you've set up your $PATH correctly, you can now use
the tinygo command as usual:
tinygo version
You can also do many other things from this environment. Building and
flashing should work as you're used to: it's not a VM or container so
there are no access restrictions.
This allows us to test and use LLVM 17, now that it is available in
Homebrew.
Full support for LLVM 17 (including using it by default) will have to
wait until Espressif rebases their Xtensa fork of LLVM.
This commit adds support for LLVM 16 and switches to it by default. That
means three LLVM versions are supported at the same time: LLVM 14, 15,
and 16.
This commit includes work by QuLogic:
* Part of this work was based on a PR by QuLogic:
https://github.com/tinygo-org/tinygo/pull/3649
But I also had parts of this already implemented in an old branch I
already made for LLVM 16.
* QuLogic also provided a CGo fix here, which is also incorporated in
this commit:
https://github.com/tinygo-org/tinygo/pull/3869
The difference with the original PR by QuLogic is that this commit is
more complete:
* It switches to LLVM 16 by default.
* It updates some things to also make it work with a self-built LLVM.
* It fixes the CGo bug in a slightly different way, and also fixes
another one not included in the original PR.
* It does not keep compiler tests passing on older LLVM versions. I
have found this to be quite burdensome and therefore don't generally
do this - the smoke tests should hopefully catch most regressions.
This adds true GOOS=wasip1 support in addition to our existing
-target=wasi support. The old support for WASI isn't removed, but should
be treated as deprecated and will likely be removed eventually to reduce
the test burden.
The Linux artifacts have clear names (linux-amd64-double-zipped etc),
but the MacOS and Windows ones didn't. This patch renames these artifact
names to be more readable, especially when downloading the artifacts.
This makes reviewing PRs a lot easier because I don't have to run this
myself :)
This only uses the drivers repo so far, which is a good starting point
but doesn't include binary size changes for WebAssembly for example. A
future change could add some real-world programs to get a better idea of
the real-world impact.
To be clear: the intention is not to just look at the number at the
bottom. It is important to look at the actual size difference to see the
overall pattern (like, the difference may be due to a few outlier).
This test only applies when using the built-in LLVM version. This way,
we have a stable LLVM version to test against. Distribution versions of
LLVM (especially Debian) tend to be patched in a way that affect the
results.
This should fix a number of concurrency/threading issues.
I had to force-disable concurrency in the linker using a hack. I'm not
entirely sure what the cause is, possibly the MinGW version (version 12
appears to work for me, while version 11 as used on the GitHub runner
image seems to be broken).
There are a few ways to fix this in a better way:
* Fix the underlying cause (possibly by upgrading to MinGW-w64 12).
* Add the `--threads` flag to the LLD MinGW linker, so we can use a
regular parameter instead of this hack.
It can be difficult to find what went wrong in a test. Omitting -v
should make it easier to see the failing tests and the output for them
(note that output is still printed for tests that fail).
