start addresses of every function in a file. Often times a file can get
stripped of some of its (non-exported) symbols -- but in Mach-O binaries
there is a separate section (LC_FUNCTION_STARTS) which doesn't get
stripped out and provides the start address of every function in the
file. This information can also be gotten from the eh_frame unwind
information if that is present. lldb uses these sources of information
to supplement the symbol table and add these "unnamed_function" symbols
when it reads in the object file.
Thanks for the suggestion. It ended up simply being that "private"
didn't work at all with the debugger. Switched to "internal" linkage
(after a suggestion on #llvm) and everything works as expected.
