Commit f95b9001 by Richard Kenner
Options

(cmpxf): Don't call force_const_mem, it looses for PIC; 

get predicates right instead.  Get rid of separate DEFINE_EXPAND.
(addxf3, subxf3, mulxf3, divxf3): Likewise.
(All XFmode patterns): Delete `F' and `G' constraints.
(absxf2): Delete spurious condition on TARGET_FPA.
(negxf2): Likewise.
