Dwarf Assembly

Some experiments around compiling the most used Dwarf informations (ELF debug data) directly into assembly.

This project is a big work in progress, don't expect anything to be stable for now.

Dependencies

As of now, this project relies on the following libraries:

These libraries are expected to be installed somewhere your compiler can find them.

Scripts and directories

  • ./generate_eh_elf.py: generate .eh_elf.so files for a binary (and its dependencies if required)
  • ./compare_sizes.py: compare the sizes of the .eh_frame of a binary (and its dependencies) with the sizes of the .text of the generated ELFs.
  • ./extract_pc.py: extracts a list of valid program counters of an ELF and produce a file as read by dwarf-assembly
