@title VMSR
@id 409
@desc {
Move to Advanced SIMD and Floating-point Extension System Register from ARM core register moves the value of an ARM core register to a Floating-point system register. Depending on settings in the CPACR, NSACR, HCPTR, and FPEXC registers, and the security state and mode in which the instruction is executed, an attempt to execute a VMSR instruction might be UNDEFINED, or trapped to Hyp mode. Summary of general controls of CP10 and CP11 functionality on page B1-1230 and Summary of access controls for Advanced SIMD functionality on page B1-1232 summarize these controls. When these settings permit the execution of floating-point and Advanced SIMD instructions, if the specified Floating-point Extension System Register is not the FPSCR, the instruction is UNDEFINED if executed in User mode. Note VMSR on page A8-956 describes the valid application level uses of the VMSR instruction.
