between GENERAL_REGS and FP_REGS. On the 32-bit port, we use the
location at SP-16 because PA 1.X only supports 5-bit immediates for
floating-point loads and stores. We don't expose this location in
the RTL to avoid scheduling related problems. For example, the
store and load could be separated by a call to a pure or const
function which has no frame and this function might also use SP-16.
We have 14-bit immediates on the 64-bit port, so we use secondary
memory for the copies. */
