This speeds up the generation of SVD files, for example as part of a
package build (where parallelism may not be desired, or tools should
auto-detect the number of threads to use).
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).
- Use compiler-rt and picolibc instead of avr-libc.
- Use ld.lld instead of avr-ld (or avr-gcc).
This makes it much easier to get started with TinyGo on AVR because
installing these extra tools (gcc-avr, avr-libc) can be a hassle.
It also opens the door for future improvements such as ThinLTO.
There is a code size increase but I think it's worth it in the long run.
The code size increase can hopefully be reduced with improvements to the
LLVM AVR backend and to compiler-rt.
The Espressif fork of LLVM now has Xtensa support in the linker LLD.
(This support was written mosly by me). This means we don't have to use
the Espressif GNU toolchain anymore and makes installing TinyGo simpler.
In the future, this also paves the way for ThinLTO support. Right now it
is mostly just a way to simplify TinyGo installation and speed up CI
slightly.
This fixes https://github.com/tinygo-org/tinygo/issues/3146 by using a
prebuilt Docker image. I don't remember why I used `setup-go` but
probably to make it faster (setup-go usually uses cached binaries).
This updates to setup-go@v3 which is the only updated version (v2 last
updated in feb), and employs its cache to simplify workflow
configuration.
Notably, we can't do this for Alpine until #3146

This makes it easier to move the TinyGo compiler between Linux versions
because it doesn't depend on any system libraries anymore. For example,
binaries should be able to run on old Linux versions and on
distributions without glibc (such as Alpine Linux).
This commit will start to use a few more WebAssembly features, such as
bulk memory operations. This results in a significant code size saving.
How much it saves varies a lot but it's typically around 1300 bytes.
This change is possible by bumping our minimum Node.js version to 14.
The previous LTS version (12) has been marked end of life, so we can
start to depend on features in the current oldest LTS version, which is
version 14. Browsers have been supporting these features for a long time
now, it's just Node.js that prevented us doing this before.
