This switches the Espressif fork from LLVM 19 to LLVM 20, so we can use
the improvements made between those LLVM versions. It also better aligns
with the system-LLVM build method, which currently also defaults to LLVM
20.
Note that this disables the machine outliner for RISC-V. It appears
there's a bug in there somewhere, with the machine outliner enabled the
crypto/elliptic package tests fail with -target=riscv-qemu.
This should ideally be investigated and reported upstream.
Instead of relying on a build when TinyGo is being built, do it like all
other libraries when it is needed.
This brings a few benefits:
* No more running `make wasi-libc` on the command line as a special
case for WebAssembly. The generic `git submodule update --init` step
is now enough for wasi-libc.
* It becomes much easier to customize the build per system. For
example: include/exclude malloc as needed, disable/enable bulk
memory operations per target, etc.
This adds linux/mipsle (little endian Mips) support to TinyGo.
It also adds experimental linux/mips (big-endian) support. It doesn't
quite work yet, some parts of the standard library (like the reflect
package) currently seem to assume a little-endian system.
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 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.
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 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.
