 Hi Dave,
 
 I guess this feature was lost in the recent modernization of the HP-UX
 stuff.  The preferred way to handle this nowadays in GDB is to use
 something called pseudo-registers.  But this requires that
 single-precision and double-precision registers have different names.
 The natural way to this for PA-RISC is to use "frN" as the name of the
 full-width double-precision register and use "frNR" and "frNL" as
 names for the single-precision halves.  This is consistent with the
 "HP Assembler Reference Manual", but it wouldn't exactly help people
 who expect the gdb 5.0 behaviour.
