Don't block forever if there's nothing to receive. On the other hand,
process the entire FIFO, not just a single byte.
This fixes an issue where the rp2350 would hang after programming through
openocd, where the UART0 interrupt would be spuriously pending.
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.
Apparently this package imports `runtime.getRandomData` from the gojs
module. This is not yet implemented, but simply allowing this package to
do such imports gets crypto/sha256 to compile.
Right now it doesn't compile, with errors like the following:
# machine
/app/tinygo/src/machine/board_pico.go:7:13: undefined: GPIO0
/app/tinygo/src/machine/board_pico.go:8:13: undefined: GPIO1
/app/tinygo/src/machine/board_pico.go:9:13: undefined: GPIO2
/app/tinygo/src/machine/board_pico.go:10:13: undefined: GPIO3
[...etc...]
This patch should fix that.
* machine: add support for core voltage adjustments to rp2040
In preparation for bumping the core frequency of the rp2040, this
change implements the required core voltage adjustment logic.
* machine: bump rp2040 to 200MHz
Follow-up to #4728 which implemented the algorithm for finding the
dividers.
The calculation is computed at compile time by interp, as verified by
building example/blinky1 for -target pico.
The upstream one assumes it's running on a Unix system (which makes
sense), but this package is also used on baremetal. So replace it on
systems that need a replaced syscall package.
We can't use the bytes package in Go 1.24 since it would result in an
import cycle. Therefore, use bytealg.Index instead.
(I'm not sure this code is correct - just searching for a range of bytes
seems brittle. But at least this commit shouldn't change the code).
This mangles CGo identifier names to something like "_Cgo_foo" instead
of using literal identifiers like "C.foo". This works around
https://github.com/golang/go/issues/71777.
I don't like this solution, but I hope we'll find a better solution in
the future. In that case we can revert this commit.
older behavior for wasi modules to not return an exit code as if they were reactors.
See #4726 for some details on what this is intended to address.

This ensures:
1. The xorshift state is initialized during interp.
2. The xorshift state gets initialized to a real random number on
hardware that supports it at runtime.
This fixes a big binary size regression from the previous commit. It's
still not perfect: most programs increase binary size by a few bytes.
But it's not nearly as bad as before.
Previously, if a function couldn't be interpreted in the interp pass, it
would just be run at runtime and the parameters would be marked as
potentially being modified. However, this is incorrect: the function
itself can also modify memory. So the function itself also needs to be
marked (recursively).
This fixes a number of regressions while upgrading to Go 1.24.
This results in a significant size regression that is mostly worked
around in the next commit.
Modify the ID used for looking up the reference, based on suggestion made by @prochac
Also use console.error in the caase that the reference is not found, since it is now actually
known to be an error.
`tinygo build -o /path/to/out .` expected `/path/to/out` to already exist, which is different behaviour to `go build`. This change ensures tinygo creates any directories needed to be able to build to the specified output dir.
