            Bug ID: 16195
           Summary: Warnings from systemtap probes in libm in
                    non-systemtap configurations
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
                CC: siddhesh at redhat dot com

As I noted in https://sourceware.org/ml/libc-alpha/2013-10/msg00502.html
building for a non-systemtap configuration produces warnings building libm of
the form:

../sysdeps/ieee754/dbl-64/e_atan2.c:602:4: warning: the address of 'p' will
always evaluate as 'true' [-Waddress]

The probes need fixing so they don't generate warnings in such a configuration.
