These were useful when extending libdwarf/ctfconvert/readelf to handle DWARF generated by gcc 12, which is version 5 by default.

If these two are out of sync, as is the case if one builds a commit prior to the introduction of the libz dependency, then the build fails when trying to statically link nm(1). Mitigate the problem by defining a weak uncompress() symbol which simply returns an error. This ensures that the build won't fail when statically linking libdwarf without zlib. The downside is that any tools using libdwarf without zlib will now hit a runtime error if they attempt to decode compressed sections, but at least they'll fail deterministically, and compressed debug info is only enabled by default in main. In particular, this fixes building of branches lacking commit dbf05458e3bd, such as releng branches, stable/12 and 13 and old revisions of main. Previously the nm(1) build would fail with: ld: error: undefined symbol: uncompress >>> referenced by libdwarf_elf_init.c:233 >>> (/usr/src/contrib/elftoolchain/libdwarf/libdwarf_elf_init.c:233) >>> libdwarf_elf_init.o:(_dwarf_elf_init) in archive >>> /usr/lib/libdwarf.a Reported by: dim, ler, krion Reviewed by: imp, emaste Fixes: dbf05458e3bd ("libdwarf: Support consumption of compressed ELF sections") MFC after: 1 week Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D33419 2021-12-06T15:37:49Z Mark Johnston markj@FreeBSD.org 2021-12-06T15:37:49Z urn:sha1:dbf05458e3bd8c46f5e49918593557293a29d41a Automatically decompress zlib-compressed debug sections when loading them.
