| I have a compiled binary whose code size I would like to make smaller (ensmallen?) So I’d like to be able to see how many bytes each of its functions/methods/constants/etc. take up. Now, the output of ‘otool’ seems to include enough information to derive that, but it’s not in a human comprehensible form — for example, it lists the address of each symbol, but to find sizes you'd have to sort by address and then subtract adjacent lines.
Long ago I remember there being a tool that would crunch these numbers and show you a listing of symbols and sizes. But I can’t remember what it was called. Anyone know of such a beast? (And no, Mach-O-Scope doesn’t seem to do this, unless I’m missing a setting.)
