Language server for Assembly

[Tarang74]

I use AVR ASM in education, and would like to ask if there is any language support for AVR Assembly?

I'm primarily interested in:

1. Using Ctrl + Space to suggest macros or instructions.
2. Using Alt + Click to navigate to external files such as header files: #include <avr/io.h> etc.
3. Better syntax highlighting.

These features will be specific to the AVR Instruction Set.

If this is not supported by PIO, are there other extensions that may help, or should I consider developing my own language server?

Thank you for your help.
