* Add STM32G0B1 target support
Introduce support for STM32G0B1 microcontrollers, including target-specific JSON files, linker scripts, and runtime initialization. This update adds hardware support for GPIO, UART, SPI, I2C, timers, and additional board-specific configurations like Nucleo-G0B1RE.
* Update STM32G0 clock initialization to 64MHz and adjust related configurations
Reconfigure STM32G0 to use a 64MHz system clock via PLL with HSI16 as the source. Update flash latency, prescaler settings, and I2C timing values to reflect the new frequency.
* Cleanup
* Cleanup
* Add STM32G0-specific UART implementation
Introduce a new UART implementation for the STM32G0 series with chip-specific setup and configuration methods. Update the generic STM32 UART code to exclude STM32G0.
* Refactor STM32G0 runtime and machine code to utilize chip-specific register access functions
Simplify and standardize register operations with dedicated setter methods in the STM32G0 runtime and machine code and cleanup redundant syntax.
* Remove redundant commented-out APBENR1 register operations in STM32G0 machine code
* Introduce FDCAN support for STM32G0B1 series
Add FDCAN peripheral implementation targeting STM32G0B1, including support for standard, extended identifiers, and bit rate configuration. Update board files to include FDCAN pins, instances, and clock configuration for Nucleo-G0B1RE and Amken Trio boards.
* Create "pico2-ice" target board
This board has an rp2350b chip on it, as well as a Lattice Semiconductor
iCE40UP5K FPGA. More details of this open hardware board here:
https://pico2-ice.tinyvision.ai/
Tested on a pico2-ice board with:
~/go/bin/tinygo flash -target=pico2-ice src/examples/blinky1/blinky1.go
which blinks the GREEN LED (connected to GPIO0) on this board.

* More silkscreen labels for pico2-ice board
Reading the schematic and the rev2 board viewer:
https://raw.githubusercontent.com/tinyvision-ai-inc/pico2-ice/refs/heads/main/Board/Rev2/bom/ibom.html
concluded that the RP2350B GPIO pins are not labeled with these
pin numbers in the silkscreen. Instead, the silkscreen refers to
uses of the GPIOs or the ICE numbered pins. RP2340B devoted pins
map to the A1..4 B1..4 pins on the RP PMOD connector. Also
silkscreen "~0".."~6" are labeled as pins N0..N6.

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.
This adds support for `-gc=boehm` on `-target=wasip1` and `-target=wasm`
(in a browser or NodeJS). Notably it does *not* add Boehm GC support for
`-target=wasip2`, since that target doesn't have a real libc.
This commit adds support for a scheduler that runs a scheduler on all
available cores. It is meant to be used on baremetal systems with a
fixed number of cores, such as the RP2040.
The initial implementation adds support for multicore scheduling to the
riscv-qemu target as a convenient testing target. This means that this
new multicore scheduler is tested in CI, including a bunch of standard
library tests (`make tinygo-test-baremetal`). This should ensure the new
scheduler is reasonably well tested before trying to use it on
harder-to-debug targets like the RP2040.
* machine: add support for BTT SKR Pico
Adds support for the BigTreeTech SKR Pico 3D-printer mainboard.
This board uses the RP2040.
* Fix build tag
* Add I2C defaults
* Run UART test instead of blinky1
* Use NoPin for I2C and SPI on BTT SKR Pico
* Cleanup comments
* Don't use ADC pin names
Instead of just incrementing the timestamp, this causes the system to
actually sleep when calling time.Sleep. The direct effect is that this
works as expected:
$ tinygo run -target=riscv-qemu examples/serial
hello world!
hello world!
hello world!
[..etc]
This commit also adds a bare bones handler for exceptions (such as
invalid memory writes), since we're adding an interrupt handler anyway.
While this patch doesn't add that much functionality, having interrupt
support is going to be needed for multicore support on riscv-qemu. My
plan is to first add this support to riscv-qemu (based on the earlier
work I did for the RP2040 and demoed at FOSDEM 2025) and once the basics
are in place and fully tested we can extend this support to the RP2040.
Writing for QEMU first makes it much easier to debug any issues that
will come up.
* machine/rp2350: add flash support for rp2350
* combine duplicate files
* clean things up and group by source file
* add stubbed out xip cache clean func if needed in the future
* update flash_enable_xip_via_boot2
* remove unused macros and fix inconsistent formatting
* make flash size configurable like rp2040
* add missing flash size configs
* retain big Go CGo compatibility per #4103
* clarify CS0_SIZE source and remove single-use typedef
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).
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.

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.
