            Bug ID: 30916
           Summary: addr2line testsuite fails when targeting PowerPC 64
                    big-endian with ELFv2 ABI
           Product: binutils
           Version: 2.41
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: awilfox at adelielinux dot org
  Target Milestone: ---

addr2line fails its test suite when the target is a big endian, 64-bit PowerPC
system with ELFv2 ABI.

musl libc uses ELFv2 on both endians of PowerPC64, and I know that there is an
experimental glibc port that uses ELFv2.  This naive patch fixes it for musl:

.. but obviously does not fix it for any other ELFv2 target.
