            Bug ID: 17263
           Summary: [powerpc] __get_clockfreq broken for 32-bit non-power4
                    glibc
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c uses the VDSO to get an
hp_timing_t result.  The VDSO always provides a 64-bit result, but hp_timing_t
is 32-bit if the power4 sysdeps directories aren't used, resulting in only r3
(the high part of the result, = 0) being used, a value of 0 being returned and
test-gettimebasefreq failing.
