I'd suggest 'debuginfo' and a Git-alike set of subcommands:

   debuginfo help
   debuginfo check
   debuginfo check framepointers
   debuginfo check cfi

Such a command scheme keeps open various future commands, such as:

   debuginfo show
   debuginfo size
   debuginfo compress
   debuginfo strip

etc.

I also checked that there does not appear to be such a Linux tool with such a name 
at the moment.

Thanks,

	Ingo
