4.2.13 ARMulif_CPWrite
This function calls the
write method for a coprocessor. It also intercepts calls to write
the FPE emulated registers.
Syntax
int ARMulif_CPWrite(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
dependent.
Return
The function must return:
•
ARMul_DONE , if the register can be written
•
ARMul_CANT , if the register cannot be written.
