If we are only interested in kernel loadable modules then we could run eu-strip
--reloc-debug-sections[-only] before running dwz:
--reloc-debug-sections Resolve all trivial relocations between debug
sections if the removed sections are placed in a
debug file (only relevant for ET_REL files,
operation is not reversable, needs -f)
--reloc-debug-sections-only
Similar to --reloc-debug-sections, but resolve all
trivial relocations between debug sections in
place. No other stripping is performed (operation
is not reversable, incompatible with -f, -g,
--remove-comment and --remove-section)
That way there are no relocations anymore between the .debug_sections. Which is
fine because although the .ko files are ET_REL you wouldn't link them with any
other object file. dwz should then double check the .ko is really a kernel
module on which eu-strip --reloc-debug-sections has been run before processing
the file.
