I do wonder if it would be helpful for the API to be able to provide a 'prefix value' for prematching. So that, for example, -mcpu=cortex would pass 'cortex' as a pre-match and then the compiler could supply just the valid cpus that start with cortex. or -mcpu=cortex-a5+ would pass 'cortex-a5+' and the compiler can supply the valid extensions to that CPU.
