clang 14 removed -gz=zlib-gnu support and ld.lld removed linker input support for zlib-gnu in D126793. Now let's remove zlib-gnu from llvm-objcopy. * .zdebug* sections are no longer recognized as debug sections. --strip* don't remove them. They are copied like other opaque sections * --decompress-debug-sections does not uncompress .zdebug* sections * --compress-debug-sections=zlib-gnu is not supported It is very rare but in case a user has object files using .zdebug . They can use llvm-objcopy<15 or GNU objcopy for uncompression. --compress-debug-sections=zlib-gnu is unlikely ever used by anyone, so I do not add a custom diagnostic.
