With a few small modifications, all the problems with `-gc=precise` in
WebAssembly seem to have been fixed.
I didn't do any performance measurements, but this is supposed to
improve GC performance.
This adds support for //go:wasmexport with `-target=wasm` (in the
browser). This follows the //go:wasmexport proposal, meaning that
blocking functions are not allowed.
Both `-buildmode=default` and `-buildmode=c-shared` are supported. The
latter allows calling exported functions after `go.run()` has returned.
This adds support for the `//go:wasmexport` pragma as proposed here:
https://github.com/golang/go/issues/65199
It is currently implemented only for wasip1 and wasm-unknown, but it is
certainly possible to extend it to other targets like GOOS=js and
wasip2.
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.
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.
These functions are used by the binary blobs that implement wifi/BLE on
the ESP32-C3. While this is a lot of lines of linker script, I think
it's a good idea to add them here (instead of in a separate library)
because they're part of the ESP32-C3 hardware.
