Compare the output of nm -aU instead? That gives you the actual symbol table,
which is a better comparison, and it’s slightly easier to use because you don’t
have to use a regex to find what you’re looking for. It protects against ninja
and Xcode stripping the same number of different symbols.

[Nico, 2013/09/13 20:11:07]

Oh, nice. Why -U?

(Done for `nm -a`)

To not show undefined symbols, just so that you can focus on your own symbols.
But I guess it doesn’t hurt to omit -U and include the undefined symbols either.
