The AVR backend now supports the -masm-len-notes and -Wasm-len-notes options. These options control whether assembly length notes are included in the generated assembly code and whether warnings are generated if assembly length notes are missing, respectively. This addition allows developers more control over the verbosity and information included in AVR assembly outputs.
