xPack GNU RISC-V Embedded GCC v12.2.0-1 with support of WCH RISCV CH56x... "WCH-Interrupt-fast"

Release 12.2.0-1 is a new release of the xPack RISC-V Embedded GCC package, following the upstream GNU GCC release.

• This version is the same as https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/tag/v12.2.0-1 but it add support of WCH RISCV CH56x... "WCH-Interrupt-fast"
  • This toolchain has been tested on HydraUSB3 v1 with WCH CH569 but it shall work also with all CH32V series (like CH32V003, CH32V103 and CH32V307) using special interrupt "WCH-Interrupt-fast"
    • Example usage:
      __attribute__((interrupt("WCH-Interrupt-fast"))) void IRQHandler() { }
  • For more details see the patch https://github.com/hydrausb3/riscv-none-elf-gcc-xpack/blob/xpack/patches/gcc-12.2.0.patch.diff
    • Thanks to @davidcarne for that amazing contribution
