When debugging is enabled for interp, print better errors in a specific
case.
Before:
!! revert because of error: interp: unsupported instruction (to be emitted at runtime)
After:
!! revert because of error: /usr/local/go1.24.0/src/regexp/syntax/parse.go:927:27: interp: unsupported instruction (to be emitted at runtime)
So this adds error location information, which can be quite useful.
the test-macos-homebrew job, and it conflicts with the actual build
that we want, which is macOS 14 for backwards-compatibility.

GitHub org. The git server for git.musl-libc.org is having troubles,
and it also seems like a safer bet to have our own mirror just in case.

- do not install cmake, instead use the version already installed
- add macOS 15 to the CI builds
- update a could of GH actions to latest release
- update Go version being use to Go 1.25.1

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.
The revive command seems to have had a syntax error in the file
input glob. It appears to have been broken in a way that did not
result in a return code being set. This change uses 'find' to
build the input to the linter.
Note that it is expected to fail the CI script, because it is
uncovering some existing lint issues that were not being caught.
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).
In some cases, e.g nothing connected on the bus, repeated resume-stop sequences can lead to the bus never reaching the stop state, hanging Tx.
This change ensures the resume-stop sequence is submitted once on error. It also moves the error code read to before the sequence to ensure it's valid.
Fixes: #4998
Writing to the UART takes time and that may not be a good idea inside an
interrupt, but it is essential for debugging sometimes (especially since
USB-CDC typically doesn't work inside an interrupt).
This fixes UART support in interrupts for the RP2040 at least. You can
test it with `-serial=uart` and connecting a USB-UART adapter to the
right pins.
Account for the sleep queue base time in the computation of the wakeup
time.
Tested with the following program on pico2.
func main() {
go func() {
for i := range 60 {
const delay = 20 * time.Millisecond
before := time.Now()
time.Sleep(delay)
if d := time.Since(before); true || d < delay {
log.Println(i, "actual", d, "delay", delay)
}
}
}()
time.Sleep(500 * time.Millisecond)
log.Println("******** done sleeping ********")
select {}
}
Without this change, the program would print lines such as:
17 actual 15.494ms delay 20ms
18 actual 15.49ms delay 20ms
19 actual 15.585ms delay 20ms
20 actual 15.493ms delay 20ms
21 actual 15.494ms delay 20ms
22 actual 15.487ms delay 20ms
23 actual 15.498ms delay 20ms
******** done sleeping ********
24 actual 15.548ms delay 20ms
25 actual 20.011ms delay 20ms
26 actual 20.01ms delay 20ms
27 actual 20.011ms delay 20ms
28 actual 20.015ms delay 20ms
Note that while more than one sleeping goroutine is in the timer queue,
the sleep duration is 5ms short.
* Add -o flag support to flash command. Fixes#4937
* Remove empty outpath check in validateOutputFormat

This gets the path package tests to pass, so we can move ahead with Go
1.25. It should be implemented in the future at some point (that, or
we'll use the upstream testing package instead).
Since we switched to OS threads for goroutines, the
testdata/goroutines.go test has been flaky. Not surprising, if threads
need to be scheduled within 1ms on a busy CI system. This PR makes the
test a bit less flaky (hopefully) by increasing the time to 100ms.
Found this bug while trying to use the upstream testing package instead
of our own. The io/fs package wasn't passing, because the test was run
in a separate goroutine (and therefore a separate thread, with its own
stack) instead of all in the same thread with our own stack
creation/switching implementation.
