This requires an API introduced in MacOS 11. I think that's fine, since
the version before that (MacOS 10.15) is EOL since 2022. Though if
needed, we could certainly work around it by using an older and slightly
less nice API.
|
|
This is needed for the internal/syscall/unix package.

The git hash that's part of `tinygo version` is now read from the binary
itself instead of embedding it with a `-ldflags` flag. This means it is
also present when building TinyGo using `go build` or `go install`.

This makes it easier to find what actually went wrong in CI.
This flag was added in #4431, I think it was unintentional.
|
|
I've had this board for a while now, but never added proper TinyGo
support. So here is a PR to do just that.
|
|
These boards probably haven't been working since the addition of I2C,
because they were missing some constants in the machine package.

This version probably isn't as fast as the upstream version, but it is
good enough for now. It also doesn't free unreferenced handles like the
upstream version.

I tried implementing enough CGo support to get the native os/user
package to work. But I hit a few bugs, probably in CGo itself. Then I
realized I could just as well set the osusergo build tag to disable CGo
for this specific case.
This actually gets the os/user package to work correctly on Linux (I
confirmed it returns my name/uid/homedir etc). On other systems, it
probably just returns an error if it can't determine these kinds of
things. But that's no worse than the current behavior which just doesn't
do anything at all.

Do manual fix in GNUmakefile, since spellchecking that is just too meta.

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.

Example output:
$ make help
clean Remove build directory
fmt Reformat source
fmt-check Warn if any source needs reformatting
gen-device Generate microcontroller-specific sources
llvm-source Get LLVM sources
llvm-build Build LLVM
lint Lint source tree
spell Spellcheck source tree
Might even work on windows, since git for windows comes with awk.

The C printf function is sometimes needed for C files included using
CGo. This commit makes sure they're available on all systems where CGo
is fully supported (that is, everywhere except on AVR).
For baremetal systems using picolibc, I've picked the integer-only
version of printf to save on flash size. We might want to consider
providing a way to pick the floating point version instead, if needed.
|

These libraries will be automatically built when needed and cached.
The main reason these were needed is for play.tinygo.org, but I've now
prebuilt them there directly (so they don't need to be built for every
tarball).

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.

- add internal/wasm-tools/go.mod file to depend on wasm-tools-go
- copy package cm into src/internal/cm
- remove wasm-tools-go "vendor" submodule
internal/tools: fix typo
go.{mod,sum}, internal/tools: add wit-bindgen-go to tools
GNUmakefile: use go run for wit-bindgen-go
GNUmakefile: add tools target to go:generate tools binaries in internal/tools
GNUmakefile: add .PHONY for lint and spell
GNUmakefile, internal/cm: vendor package cm into internal/cm
go.{mod,sum}: update wasm-tools-go to v0.1.4
internal/wasi: use internal/cm package
remove submodule src/vendor/github.com/ydnar/wasm-tools-go
GNUmakefile: add comment documenting what wasi-cm target does
go.{mod,sum}: remove toolchain; go mod tidy
go.mod: revert to Go 1.19
go.mod: go 1.19
go.{mod,sum}, internal/{tools,wasm-tools}: revert root go.mod file to go1.19
Create a wasm-tools specific module that can require go1.22 for wasm-tools-go.

Compilers like GCC keep adding new checks that produce new warnings.
Sometimes it can be false positives.
Do not treat such warnings in binaryen library as errors. tinygo won't
be able to provide zero warnings in its dependencies.
Closes #4332

* all: wasip2 support

The machine package wasn't tested for every board. Therefore, add a new
serial-like test that also tries to import the machine package. This
should highlight potential issues in the future.

The current list of targets does not build wasm-ld.
wasm-ld is a symlink created in ./llvm-build/bin pointing to ./lld.
Add the "lld" build target to get wasm-ld into ./llvm-build/bin.
Fixes a build failure where wasm-ld is not found.

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.

This makes all rp2040 boards available for simulation using
-tags=<board_name>. Importantly, this includes the Gopher Badge which
I'm working on to add to the TinyGo Playground.

This eliminates the 'wasi' build tag in favor of 'GOOS=wasip1', introduced in Go 1.21.
For backwards compatablity, -target=wasi is a synonym for -target=wasip1.
|
|
This new library is needed for wasm targets that aren't WASI and don't
need/want a libc, but still need some intrinsics that are generated by
LLVM.
|
|
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 way you can for example run `make test GOTESTPKGS=./builder` to
only test the builder package.
I've often done this by manually modifying the Makefile, so having a
make parameter available would make this much easier.
|
|
Disable the googletest dependency so that we can avoid that submodule
dependency.
