* wasm: patch wasm_exec.js and wasm_exec_node.js from Go 1.18+
Port this commit https://github.com/golang/go/commit/680caf15355057ca84857a2a291b6f5c44e73329 removing polyfills from `wasm_exec.js`, now the environment is expected to provide all the required polyfills.
`wasm_exec.js` now only provides stub fallbacks for globalThis.fs and globalThis.process.
All NodeJS specific code is now in a separate file `wasm_exec_node.js` with its required polyfills.
* feat: bump minimum node version to 22
Drops official support for NodeJS 18 for WASM by removing the provided polyfills in the `wasm_exec.js`.
Now the environment is expected to provide the polyfill if it is running on older NodeJS versions
The new minimum required version for WASM is NodeJS 22+.
* chore: removed wrong comment
`wasm_exec_node.js` no longer contains the polyfill for NodeJS 18
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.
With these flags, the TinyGo binary gets 18.8MB (11.6%) smaller. That
seems like a quite useful win for such a small change!
This is only for Linux for now. MacOS and Windows can be tested later,
the flags for those probably need to be modified.
Originally inspired by:
https://discourse.llvm.org/t/state-of-the-art-for-reducing-executable-size-with-heavily-optimized-program/87952/18
There are some other flags like -Wl,--pack-dyn-relocs=relr that did not
shrink binary size in my testing, so I've left them out.
This also switches the linker to prefer mold or lld over the default
linker, since the system linker is usually ld.bfd which is very slow.
(Also, for some reason mold produces smaller binaries than lld).
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.
Run a range of tests in CI, to make sure browser wasm and baremetal
don't regress too badly.
I have intentionally filtered out tests, so that newly added tests to
TEST_PACKAGES_FAST will be added here as well (and can be excluded if
needed).
It looks like we didn't have any tests for wasm. Having one tests is not
much, but it proves that the infrastructure works and it actually
verifies a fix to https://github.com/tinygo-org/tinygo/issues/4777.
We should add more packages to this list in the future.
TODO: Remove the go.mod/go.sum in internal/tools once doing so doesn't break CI (e.g. once we drop support for go 1.19)
* builder/cc1as.h: fix typo found by 'make spell'
* GNUmakefile: remove exception for inbetween, fix instance now found by 'make spell'
* GNUmakefile: remove exception for programmmer, fix instance now found by 'make spell'
* go.mod: use updated misspell. GNUmakefile: add spellfix target, use it.
* ignore directories properly when invoking spellchecker.
* make spell: give internal/tools its own go.mod, as misspell requires newer go
* make lint: depend on tools and run the installed revive
(which was perhaps implied by the change that added revive to internal/tools,
but not required in GNUmakefile until we gave internal/tools its own temporary go.mod)
* .github: now that 'make spell' works well, run it from CI
* GNUmakefile: make spell now aborts if it finds misspelt words, so what it finds doesn't get lost in CI logs
* GNUmakefile: tools: avoid -C option on go generate to make test-llvm15-go119 circleci job happy, see
https://cs.opensource.google/go/go/+/2af48cbb7d85e5fdc635e75b99f949010c607786
* internal/tools/go.mod: fix format of go version to leave out patchlevel, else go complains.
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.
See https://github.com/tinygo-org/tinygo/issues/4225
Runs in both circleci and github, circleci is run on branch push, github is run on PR
Revive builds so fast, don't bother installing it; saves us wondering which one we get
Uses tools.go idiom to give control over linter versions to go.mod.
Also pacifies linter re AppendToGlobal as a token first fix.
TODO: gradually expand the number of directories that are linted,
uncomment more entries in revive.toml, and fix or suppress the
warnings lint finds.
TODO: add linters "go vet" and staticcheck
NOT TODO: don't add metalinters like golangci-lint that pull in
lots of new of dependencies; we'd rather not clutter go.mod that
much, let alone open ourselves up to the additional attack surface.
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 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.
