             Bug #: 15493
           Summary: AArch64 sigsetjmp always saves signal mask
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ports
        AssignedTo: unassigned@sourceware.org
        ReportedBy: schwab@linux-m68k.org
                CC: carlos@redhat.com, roland@gnu.org
    Classification: Unclassified


__sigsetjmp clobbers register x1 before making the tail call to __sigjmp_save,
which causes the latter to always save the signal mask.  Also, in ld.so the
signal mask never needs to be saved, so __sigjmp_save does not need to be
called.
