sucess compile but fail execute assemble MRC instruction on iOS?-Collection of common programming errors

From the ARMv7 Architecture Reference Manual:


Move to ARM core register from Coprocessor causes a coprocessor to transfer a value to an ARM core register or to the condition flags. If no coprocessor can execute the instruction, an Undefined Instruction exception is generated.

Apparently, there just isn’t where to read a value from.
