- Add ReadRegister and WriteRegister (because they're still used by
some packages).
- Fix out-of-bounds panic in I2C.Tx when either w or r has a length of
zero (or is nil).
Both of my development boards exhibit stability problems when
programming at the default 4000 kHz speed of the target/stmf32d4x
OpenOCD configuration.
Note that the speed limit must be set by an event handler, because it
is hard-coded by a similar event handler in stmf32f4x.cfg:
$_TARGETNAME configure -event reset-init {
# Configure PLL to boost clock to HSI x 4 (64 MHz)
...
# Boost JTAG frequency
adapter speed 8000 <-- resolves to 4000 kHz by the SWD interface
}
While here, replace the reference to the deprecated "stlink-v2"
configuration.
Appending to a slice can lead to a race condition if the capacity of the
slice is larger than the length (and therefore the returned slice will
overwrite some fields in the underlying array).
This fixes that race condition. I don't know how severe this particular
one is. It shouldn't be that severe, but it is a bug and it makes it
easier to hunt for possibly more serious race conditions.
sleepTicks calls machineLightSleep with the duration cast to an unsigned
integer. This underflow for negative durations.

* lint: expand to src/{os,reflect}, fix or suppress what it found
* internal/tools/tools.go: the tools idiom requires a build tag guard to avoid go test complaints
The openocd-commands option cannot refer to commands defined by the
target configuration. Lift this restriction by moving the commands to
after target loading.

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 is much, _much_ faster than __tinygo_spi_transfer which can only
transfer a single byte at a time. This is especially important for
simulated displays.
I've already implemented the browser side of this on the playground and
have used this patch for local testing where it massively speeds up
display operations.
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 is makes it easier to use these in simulation, plus it avoids
duplication. The only downside I see is that more UARTs get defined than
a board supports, but no existing code should break (no UARTs get
renamed for example).
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.
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.
Support for `-panic=trap` was previously a pass in the optimization
pipeline. This change moves it to the compiler and runtime, which in my
opinion is a much better place.
As a side effect, it also fixes
https://github.com/tinygo-org/tinygo/issues/4161 by trapping inside
runtime.runtimePanicAt and not just runtime.runtimePanic.
This change also adds a test for the list of imported functions. This is
a more generic test where it's easy to add more tests for WebAssembly
file properties, such as exported functions.
getelementptr offsets are signed, not unsigned. Yet they were used as
unsigned integers in interp.
Somehow this worked most of the time, until finally there was some code
that did a getelementptr with a negative index.
