5.5.2.45 Floating Point Environment Data Pointer (FPENV_DP_MSR)
MSR Address
Type
Reset Value
FPENV_DP_MSR provides access to the floating point (FP) environment data pointer. Software better accesses the float-
ing point environment data using the FLDENV/FSTENV and FSAVE/FRSTOR instructions.
5.5.2.46 Floating Point Environment Opcode Pointer (FPENV_OP_MSR)
MSR Address
Type
Reset Value
FPENV_OP_MSR provides access to the floating point (FP) environment opcode. Software better accesses the floating
point environment opcode using the FLDENV/FSTENV and FRSTOR/FSAVE instructions.
