binutils: backport DWARF-5 support for gold
* DWARF-5 is now used by default with gcc-11, causing
11.1.0/ld: internal error in format_file_lineno, at ../../gold/dwarf_reader.cc:2278
collect2: error: ld returned 1 exit status
in various projects (runc-opencontainers, libhybris, collada-dom)
* https://gcc.gnu.org/gcc-11/changes.html
For targets that produce DWARF debugging information GCC now defaults to DWARF version 5
(with the exception of VxWorks and Darwin/Mac OS X which default to version 2 and
AIX which defaults to version 4). This can produce up to 25% more compact debug
information compared to earlier versions.
To take full advantage of DWARF version 5 GCC needs to be build against binutils version 2.35.2 or higher.
When GCC is build against earlier versions of binutils GCC will still emit DWARF version 5 for
most debuginfo data, but will generate version 4 debug line tables (even when explicitly given -gdwarf-5).
The following debug information consumers can process DWARF version 5:
GDB 8.0, or higher
valgrind 3.17.0
elfutils 0.172, or higher (for use with systemtap, dwarves/pahole, perf and libabigail)
dwz 0.14
Programs embedding libbacktrace are urged to upgrade to the version shipping with GCC 11.
To make GCC 11 generate an older DWARF version use -g together with -gdwarf-2, -gdwarf-3 or -gdwarf-4.
