           Summary: Powerpc rs6000.md uses RS6000_RECIP_HAVE_RSQRT_P
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: meiss...@gcc.gnu.org
        ReportedBy: meiss...@gcc.gnu.org
              Host: powerpc64-linux
            Target: powerpc64-linux
             Build: powerpc64-linux


There is a typo in rs6000.md in the rsqrt<type> generator functions.  It refers
to the RS6000_RECIP_HAVE_RSQRT_P macro, but the actual macro is
RS6000_RECIP_HAVE_RSQRTE_P.  You get a warning that the function is unknown in
the build, but it doesn't stop the build since it just puts out a relocation
for the RS6000_RECIP_HAVE_RSQRT_P function to be loaded later.  However the
rsqrt<type> generators are never called, you never get an error.
