[SOLVED]Porting core micropython: architecture-specific functions

[jickster]

This isn't about all the peripherals, just the portions of the code to run core micropython.

What functions are unique to a given architecture (x86, ARM, TI-DSP)?

1. nlr-related assembly code
2. mp_uint_t gc_helper_get_regs_and_sp(mp_uint_t *regs)

Anything else?

I think that the nlr code (which I'm pretty sure can be done using setjmp/longjmp), the gchelper function, and the startup/ISR code are the primary non-peripheral things.

Supporting the native and viper code generators also requires architecture specific code, but this functionality isn't required to get MicroPython up and running.
