These should make sure basic functionality is still working.
Using the `-short` flag to avoid taking too long to run all tests (and
to install all the necessary emulators), and because some targets might
not work in older Go/LLVM versions (such as WASI).
This does _not_ run tests and checks against expected IR, because LLVM
IR changes a lot across versions.

disable lint in go 1.19 ci job
I jumped through quite a few hoops to get test-llvm15-go119 to work, but this last hoop seems not worth jumping through:
cd internal/tools && go generate -tags tools ./
/go/pkg/mod/github.com/golangci/[email protected]/mime.go:10:2: package slices is not in GOROOT (/usr/local/go/src/slices)
tools.go:12: running "go": exit status 1
make: *** [GNUmakefile:952: tools] Error 1
I mean, we could patch misspell to not use slices, or to use the prerelease slices, but...

Go 1.18 has been unsupported for quite a while now (the oldest supported
version is Go 1.21). But more importantly, the golang.org/x/tools module
now requires Go 1.19 or later. So we'll drop this older version.

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.

This adds initial support for Go 1.22. Not all new features are
supported yet.
|
|
We can now finally do it, now that Espressif has updated their fork.
|
|
The version 17 SDK adds `getpagesize`, so use it instead of hardcoding a
number (even if their implementation is _also_ a hardcoded number.)

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 is a big change: apart from removing LLVM 14 it also removes typed
pointer support (which was only fully supported in LLVM up to version
14). This removes about 200 lines of code, but more importantly removes
a ton of special cases for LLVM 14.
|
|
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.

Not all features work yet, but allow it to compile with this Go version.

- 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.

We've supported Go 1.19 for a while now, let's actually use it in CI.
|
|
|
|
|
|
Some source code wasn't part of `FMT_PATHS` so wasn't checked for
correct formatting. This change includes all this source code and
excludes cgo/testdata because it contains files that can't be parsed.
|
|
This adds early Go 1.19 support. There are a number of things that don't
work yet, but the smoke tests pass so it's at least working for a
significant subset of programs.
This change also switches from CircleCI convenience images to upstream
Go images. This makes it a bit easier to use the latest Go versions.
Also, the convenience images are not updated anymore.
|
|
This change adds support for compiler-rt, which supports float64 (unlike
libgcc for AVR). This gets a number of tests to pass that require
float64 support.
We're still using libgcc with this change, but libgcc will probably be
removed eventually once AVR support in compiler-rt is a bit more mature.
I've also pushed a fix for a small regression in our
xtensa_release_14.0.0-patched LLVM branch that has also been merged
upstream. Without it, a floating point comparison against zero always
returns true which is certainly a bug. It is necessary to correctly
print floating point values.
|
|
This removes a lot of backwards compatibility cruft and makes it
possible to start using features that need LLVM 13 or newer.
For example:
* https://github.com/tinygo-org/tinygo/pull/2637
* https://github.com/tinygo-org/tinygo/pull/2830

1.15 specific files deleted.
1.16 specific files folded carefully into generic files, with goal of reducing diff with upstream.
Follows upstream 1.16 in making PathError etc. be aliases for the same errors in io/fs.
This fixes #2817 and lets us add io/ioutil to "make test-tinygo" on linux and mac.

Switch over to LLVM 14 for static builds. Keep using LLVM 13 for regular
builds for now.
This uses a branch of the upstream Espressif branch to fix an issue,

This would conflict with our own heap. We previously defined all those
functions to make sure it's not used, but with a more recent wasi-libc
version (https://github.com/WebAssembly/wasi-libc/pull/250) we can
simply not compile the wasi-libc heap, which is the proper fix.

This adds support for building with `-tags=llvm13` and switches to LLVM
13 for tinygo binaries that are statically linked against LLVM.
Some notes on this commit:
* Added `-mfloat-abi=soft` to all Cortex-M targets because otherwise
nrfx would complain that floating point was enabled on Cortex-M0.
That's not the case, but with `-mfloat-abi=soft` the `__SOFTFP__`
macro is defined which silences this warning.
See: https://reviews.llvm.org/D100372
* Changed from `--sysroot=<root>` to `-nostdlib -isystem <root>` for
musl because with Clang 13, even with `--sysroot` some system
libraries are used which we don't want.
* Changed all `-Xclang -internal-isystem -Xclang` to simply
`-isystem`, for consistency with the above change. It appears to
have the same effect.
* Moved WebAssembly function declarations to the top of the file in
task_asyncify_wasm.S because (apparently) the assembler has become
more strict.

Originally based on a PR by @QuLogic, but extended a lot to get all
tests to pass.

The idea here is as follows:
- Run all Linux and cross compilation tests in the asser-test-linux
job.
- Only run native tests on MacOS and Windows.
This reduces testing time on MacOS and Windows, which are generally more
expensive in CI. Also, by not duplicating tests in Windows and MacOS we
can reduce overall CI usage a bit.
I've also changed the assert-test-linux job a bit to so that the tests
that are more likely to break and the tests that are only run in
assert-test-linux are run first.
|
|
Split building the release and smoke-testing the release in two, and
don't redo some tests that are already done by assert-test-linux.
Some benefits:
- Lower overall CI time because tests aren't done multiple times.
- TinyHCI can run earlier because the build-linux job is finished as
soon as the build artifact is ready.
It does however have the downside of an extra job, which costs a few
seconds to spin up and a few seconds to push and pull the workspace. But
even with this, overall CI time is down by a few minutes per workflow
run.
|
|
Instead of doing lots of repetitive tests in test-llvm11-go115 and
test-llvm11-go116, do those tests only once in assert-test-linux and
only run smoke tests for older Go versions.
Benefits:
- This should reduce total CI time, because these jobs don't do tests
that are done elsewere anyway. They only do the minimal work
necessary to prove that the given Go/LLVM version works.
- Doing all tests in assert-test-linux hopefully catches bugs that
might not be found in regular LLVM builds.

This change implements a new "scheduler" for WebAssembly using binaryen's asyncify transform.
This is more reliable than the current "coroutines" transform, and works with non-Go code in the call stack.
runtime (js/wasm): handle scheduler nesting
If WASM calls into JS which calls back into WASM, it is possible for the scheduler to nest.
The event from the callback must be handled immediately, so the task cannot simply be deferred to the outer scheduler.
This creates a minimal scheduler loop which is used to handle such nesting.

This commit adds support for musl-libc and uses it by default on Linux.
The main benefit of it is that binaries are always statically linked
instead of depending on the host libc, even when using CGo.
Advantages:
- The resulting binaries are always statically linked.
- No need for any tools on the host OS, like a compiler, linker, or
libc in a release build of TinyGo.
- This also simplifies cross compilation as no cross compiler is
needed (it's all built into the TinyGo release build).
Disadvantages:
- Binary size increases by 5-6 kilobytes if -no-debug is used. Binary
size increases by a much larger margin when debugging symbols are
included (the default behavior) because musl is built with debugging
symbols enabled.
- Musl does things a bit differently than glibc, and some CGo code
might rely on the glibc behavior.
- The first build takes a bit longer because musl needs to be built.
As an additional bonus, time is now obtained from the system in a way
that fixes the Y2038 problem because musl has been a bit more agressive
in switching to 64-bit time_t.

This is for consistency with Clang, which always adds a CPU flag even if
it's not specified in CFLAGS.
This commit also adds some tests to make sure the Clang target-cpu
matches the CPU property in the JSON files.
This does have an effect on the generated binaries. The effect is very
small though: on average just 0.2% increase in binary size, apparently
because Cortex-M3 and Cortex-M4 are compiled a bit differently. However,
when rebased on top of https://github.com/tinygo-org/tinygo/pull/2218
(minsize), the difference drops to -0.1% (a slight decrease on average).
