  Porting `compiler-rt` intrinsics to Rust

  

  I'm glad to inform y'all that after a year, the infamous LLVM ERROR: Not supported instr bug¹ has been finally fixed and today's nightly can compile for AVR back again! 😎

  embedded-hal abstractions for AVR microcontrollers

  Also note that some libraries in the ecosystem might still use a feature called llvm_asm that was removed from rustc in 2021, so those crates might need a while to migrate to the newer asm syntax (this feature is used to provide an inline AVR assembly, e.g. to implement a cycle-accurate delay); so far I've got patches merged to https://github.com/Rahix/avr-hal & https://github.com/Rahix/avr-device :-)

  Locating this kind of bug usually starts innocently, by commenting out various places of your own code, then analyzing your program under a debugger only to find yourself doing git clone https://github.com/llvm/llvm-project a few hours later 😅
