Summary: The DWP (DWARF package) format is used to pack multiple dwo files generated by split-dwarf into a single ELF file to make distributing them easier. It is part of the DWARFv5 spec and can be generated by dwp or llvm-dwp from a set of dwo files. Caviats: * Only the new version of the dwp format is supported (v2 in GNU numbering schema and v5 in the DWARF spec). The old version (v1) is already deprecated but binutils 2.24 still generates that one. * Combining DWP files with module debugging is not yet supported.
