Adds function information to the internal data structures.
The -remove-old flag will remove any existing function information before adding new. Without this flag function information will only be added if it has previously not been added.
The -no-data-labels flag will tell the command to not try to handle certain function names as data labels and instead keep them as functions. This will lead to that these labels as included in the disassembly report as functions, even though they are most likely data. Without this options data ranges following such labels will be excluded from the report. Altering this flag implies removing old data.
