HP-PA 2.0w has 32 fullword registers and 32 floating point

registers. However, the floating point registers behave

differently: the left and right halves of registers are addressable
|

as 32 bit registers.
|

|

Due to limitations within GCC itself, we do not expose the left/right
|

half addressability when in wide mode. This is not a major performance
|

issue as using the halves independently triggers false dependency stalls
|

anyway. */
