Restoring Symbols When an Instruments Trace Shows Only Addresses
Re-symbolicate your document when addresses, rather than symbols, are displayed in trace documents generated by the Instruments analysis tool. Symbolication will map addresses to their associated symbols and line number information.
Choose File > Re-Symbolicate.
Click the Binaries tab in the Re-Symbolicate dialog.
Highlight the binary (executable) from which your trace document was made.
Click the Locate button and select the symbol file.
Re-symbolication is often necessary when you build on one machine and test performance on another. To correctly display symbols in trace documents, Instruments needs access to the specific symbol files that were generated when the executable you are testing was built.
You can narrow the list of displayed locations in the Binaries tab by typing the executable name in the search field.
