Hmmm, apparently bug got filed before entering all the text.  Anyway, here goes
again...


482.sphinx3 miscompares when built with a recent mainline and the options -O3
-mcpu=power7. The error message seen is:

*** Miscompare of an4.log

Recompiling bencmark source file lm.c with -mno-vsx -mno-altivec or
-fno-tree-vectorize results in a successful execution.
