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. + +} + +@encoding (T1) { + + @word 1 1 1 0 1 1 1 0 1 1 1 0 reg(4) Rt(4) 1 0 1 0 0 0 0 1 0 0 0 0 + + @syntax { + + @subid 2040 + + @conv { + + spec_reg = SpecRegFromReg(reg) + reg_T = Register(Rt) + + } + + @asm vmsr spec_reg reg_T + + } + +} + +@encoding (A1) { + + @word 1 1 1 0 1 1 1 0 1 1 1 0 reg(4) Rt(4) 1 0 1 0 0 0 0 1 0 0 0 0 + + @syntax { + + @subid 2041 + + @conv { + + spec_reg = SpecRegFromReg(reg) + reg_T = Register(Rt) + + } + + @asm vmsr spec_reg reg_T + + } + +} + |
