    • This is pretty unlikely in real code... · c590597c 
      This is pretty unlikely in real code, but similar to Arm, the AArch64
ABI has a bug with the handling of 128-bit bit-fields, where if the
bit-field dominates the overall alignment the back-end code may end up
passing the argument correctly.  This is a regression that started in
gcc-6 when the ABI support code was updated to support overaligned
types.  The fix is very similar in concept to the Arm fix.  128-bit
bit-fields are fortunately extremely rare, so I'd be very surprised if
anyone has been bitten by this.

    • [libbacktrace] Fix strrchr segfault · c75795fa 
      Currently, when running a libbacktrace testcase t with .gnu_debuglink to
t.debug, and t.debug having a .gnu_debugaltlink to t.alt.debug, a segfault
is triggered when calling strrchr with a NULL string from
elf_find_debugfile_by_debuglink.  The NULL string originates from the elf_add
called for the .gnu_debugaltlink, which uses NULL as filename argument.

Fix this by using "" as filename argument instead.
