            Bug ID: 403552
           Summary: s390x: wrong facility bit checked for vector facility
           Product: valgrind
           Version: 3.15 SVN
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: ---

The wrong bit number (128 instead of 129) is used when checking for the vector
facility.  This can result in an emulation error such as this:

==1206== Emulation fatal error -- Valgrind cannot continue:
==1206==   Encountered an instruction that requires the vector facility.
==1206==   That facility is not available on this host
==1206==    at 0x4015980: _dl_runtime_resolve_vx (dl-trampoline.h:82)

Such an error has been seen when running Valgrind under Qemu/KVM.
