This folder contains some utility scripts for working with the DWARF debugging data format. Currently, the scripts parse the output of the dwarfdump macOS utility (included here in the repository to preserve compatibility among macOS versions), but they can be easily modified to work with other similar utilities for dumping Mach-O DWARF information like objdump.
usage: dump-dwarf-dies.py [-h] [--children] [--filter FILTER] dwarffile symbol
This convenient script dumps DIEs at a specific offset or with a specific name, optionally filtering the output only to DIEs (as printed by dwarfdump) which contain specific strings (e.g. structure, declaration, or any other).
usage: parse-dwarf-types-to-c-source.py [-h] dwarffile offset [offset ...]
This script extracts (as compilable C sources) the definitions of the types (typedefs, structs, unions, enums) and the variables defined in a DWARF file at the specified offsets. The generated C files can be formatted more nicely with any C code beautifier.
usage: relocate-dwarf-variable.py [-h] dwarffile varname newaddr
This script can be used to change the address of any variable in a DWARF file to a new address. This can be useful, for example, when a binary with DWARF information is debugged with LLDB, since to locate variables in memory the debugger uses the addresses specified in the DWARF sections.
