[PATCH] D55091: Add --analyze option to llvm-dwarfdump

[Greg Clayton via Phabricator via llvm-commits]

clayborg added a comment.

BTW: I ran this on llvm-dwarfdump.dSYM from a release Darwin build with debug info and it found 71% inline code. I limited the inline depth for clarity.

  $ llvm-dwarfdump --analyze build/bin/llvm-dwarfdump.dSYM --max-inline-depth=2
  Inline information:
    Code size: 4477328
    Inline code size: 3197857
    Inline code percentage: 71.42%
  COUNT   SIZE    % CODE  Name
