Any chance to support ARM microcontrollers based on ARM Cortex-M4 or ARM Cortex-M7?

Hi. Congrats for the great project.
Any chance to port the code for ARM Cortex-Mx microcontrollers?
Coroutines are a great approach for systems with low RAM memory.
Thanks.

I have no intention to backport to ARM Cortex-M myself, but I could accept a PR for it in case it include tests with QEMU.

Based on a few minimal tests this code works as-is on hardfloat ARM Cortex-M4 and ARM Cortex-M7 with the arm-none-eabi-gcc compiler version 13.3.rel1.
