BinaryNinja builtin plugin
Binary Ninja already embeds a DWARF export plugin that exposes most of the functionality provided by this plugin. However, this plugin exports additional information, such as stack variables and basic blocks.
To export DWARF information from a BinaryNinja BinaryView representation, use the menu: Plugins > LIEF > Export as DWARF

This extension tries to convert most of the information registered in a BinaryView into DWARF structures, but this support is not exhaustive; here is an overview of what is and is not exported.
