Description Michael Meissner 2011-02-07 19:42:08 UTC 
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.
