This script is based on size_report from Zephyr Project scripts. It has been almost fully rewritten but the idea is the same. It uses binutils programs (readelf, nm, c++filt) to extract information about symbols and sections from an ELF file and filters them. Information is presented in a tree based on paths to files where the symbols have been defined.

Requires Python 3, readelf, nm and (optional) c++filt. To be able to extract path information about symbols from ELF file, the program should be compiled with debug information.

If installed via pip, the package provides an entry point and you can get usage info by running elf-size-analyze -h.

If working with the sources, use python -m elf_size_analyze -h for usage info.
