* libdwarf: Add some constants from DWARF 5Mark Johnston2023-02-071-0/+1
| | | | | | | | | | | | | | | This is not exhaustive - DWARF 5 has some new enumeration types not implemented here - but I think I caught all the ones that are extended in DWARF 5, plus the new compilation unit type (DW_UT_*), needed when parsing .debug_info headers. These were useful when extending libdwarf/ctfconvert/readelf to handle DWARF generated by gcc 12, which is version 5 by default.

* libdwarf: Add a weak uncompress() symbolMark Johnston2021-12-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This works around brokenness in buildworld's bootstrapping logic: it uses the source tree's metadata to collect dependency info (such as, "libdwarf depends on libz") but links against static host libraries. 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

* META MODE: Fix 'make bootstrap-tools'.Bryan Drewery2015-11-251-1/+1
| | | | | | | | | | | | | | | | | | The main problem was bitrot after elftoolchain being swapped in for the GNU toolchain. This also reworks how the list of 'host allowed' libraries is determined to only allow INTERNALLIBs, which is needed for libelftc to come in. For usr.bin/readelf use the same hack, as libelf and libdward, to bring in the needed sys/ headers for host builds. This has not yet been a problem due to readelf not being built as a host tool in buildworld. This is possible in the meta build though when building the toolchain.

There's no reason for meta mode to do this as make is already handling the rebuild dependency fine. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=291320
