Disassemble the executable created by g++ in mac osx

Question

How can I see the disassembled version of the executable (eg. a.out) of a C++ program on Mac OSx?

Answer 1

It's not exactly what you're asking for, but g++ -S produces assembly from source code and can be expected to be more readable than a disassembled version.

If you can't recompile with -S (e.g. no source code), then gdb lets you disassemble, as does objdump --disassemble. Depends what you've installed.

Answer 2

Look at otool. i.e., otool -tv a.out

Edit: To add to Tony's answer, objdump also has name demangling for C++, i.e.,

objdump -tC a.out (IIRC)
