int ARMulif_CPRead(RDI_ModuleDesc *mdesc, unsigned cpnum,
unsigned reg, ARMword *data)
where:
mdesc is the handle for the core.
cpnum is the number of the coprocessor.
reg is the number of the coprocessor register to read from, as indexed by CRn
in an
LDC or STC instruction.
data is a pointer for the data read from the coprocessor register. The number
of words transferred, and the order of the words, is coprocessor
