program information from Ghidra and BinaryNinja into a DWARF file.

So for my first post on Bluesky, I'm happy to share that LIEF (extended) is now providing an API to disassemble code (backed by the LLVM MC layer).

This disassembler is integrated with other functionalities

You can checkout lief.re/doc/latest/e... for the details.
