Clang generates a bunch of warnings/errors for GCC specific syntax (inline asm register constraints, builtins, attributes etc..). Ship Naggy with a set of blacklisted diagnostics, and make the list configurable by the user.
Fixed with commit 91b86268d3d2d2b71f46b7c75477d9eda14b8e69
No UI for adding/removing diags from the blacklist though - the user has to edit %localappdata%\Atmel\AtmelStudio\Extensions\Senthil Kumar Selvaraj\Naggy and restart Atmel Studio.
