@micropython.viper and native on ev3[support request]

[Soupborsh]

@micropython.viper
@micropython.native

Support of native compilation for ev3 would be super cool and useful for complex algorithms. It would be an easy way to make fast compiled code, make user programmers happy.
Currently if I add it, error appears:
SyntaxError: invalid arch

I used https://labs.pybricks.com/
And 4.0.0b7-ef7aae version prebuilt nightly firmware from
ev3-firmware-build-4768-gitef7aae35.zip.

Is armv5te supported in the micropython compiler? What would it take to add support for native code precompilation on ev3?

I did not publish it as an idea. Maybe it should be supported and this is just a bug. I am coming from C and Rust, python is very new for me. I did google and search here but not found relevant info.

I don't think we would add support for this to Pybricks Code since it is a quite advanced use case.

We should still be able to make some of it work on EV3 though. You will just have to use pybricksdev to load the programs.

There is an older discussion somewhere about compiling a native .mpy file somewhere around here. Although...

Is armv5te supported in the micropython compiler?

Nope:

-march=<arch> : set architecture for native emitter; x86, x64, armv6, armv6m, armv7m, armv7em, armv7emsp, armv7emdp, xtensa, xtensawin

What would it take to add support for native code precompilation on ev3?

Upstream support for this would need to be added to MicroPython. One would need to take, e.g. the armv6 implementation and modify it in places where it uses assembly instructions not available on armv5t.
