Pushed both. Thanks for the patch and testcase.
BTW. The following now also just works in case you have tools that
cannot handle the BPF relocations, but can handle separate .debug
files:
eu-strip --reloc-debug-sections -f testfile-bpf-reloc.o.debug \
testfile-bpf-reloc.o
That puts the debuginfo with all (simple) relocations resolved
into the .debug file.
--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)
This is used by some distros for the kernel .ko modules (which are
also ET_REL files) to safe space. But also might be applicable to
these BPF elf files in case they are packaged.
Cheers,
Mark
