For right now, the only things I'm interested in are the lines output by the command 'nm -gmf foo.o | c++filt -_'. This applies to anything that nm can parse, not just .o files. Although it isn't 100% necessary for what I'm doing, I am curious as to what the various sections in the mach-o binaries are. As a brief, but incomplete list, here is what I've seen so far: __DATA,__common -- Uninitialized imported global symbols __DATA,__data -- Initialized mutable variables __TEXT,__cstring -- Constant C-strings __TEXT,__eh_frame -- ??? __TEXT,__literal8 -- ??? __TEXT,__text -- Executable machine code __TEXT,__textcoal_nt -- ??? absolute -- absolute addresses - start up code? common -- ??? Can anyone fill me in on what those unknown sections are? I briefly looked at the Mac OS X ABI Mach-O File Format Reference (http://developer.apple.com/documentation/DeveloperTools/Conceptual/MachORun time/Reference/reference.html), which is where I got the few definitions I have above, but I'd like to know more.
