NettetOn a 64-bit capable processor, an execution of MOV to CR outside of 64-bit mode zeros the upper 32 bits of the control register. (See “Control Registers” in Chapter 2 of the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3A, for a detailed description of the flags and fields in the control registers.) NettetNOTE: The Intel 64 and IA-32 Architectures Software Developer's Manual consists of three volumes: Basic Architecture, Order Number 253665; Instruction Set Reference A-Z, Order Number 325383; System Programming Guide, Order Number 325384. Refer to all three volumes when evaluating your design needs.

NettetThe AMD64extensions from AMD (originally called x86-64) added a further eight registers XMM8through XMM15, and this extension is duplicated in the Intel 64architecture. There is also a new 32-bit control/status register, MXCSR. The registers XMM8through XMM15are accessible only in 64-bit operating mode.

If this option produces undesirable results of the numerical behavior of your program, you can turn the FTZ/DAZ mode off by using -no-ftz or /Qftz-in the command line while still benefiting from the O3 optimizations. bunnings qld australia
