AMD and Intel x86-64 This section describes AMD's 64-bit processors and the Intel EM64T processors, including: “x86-64 General Registers” “x86-64 Floating-Point Registers” “x86-64 FPCR Register” “x86-64 FPSR Register” “x86-64 MXCSR Register” The x86-64 can be programmed in either 32- or 64-bit mode. TotalView supports both. In 32-bit mode, the processor is identical to an x86, and the stack frame is identical to the x86. The information within this section describes 64-bit mode. The AMD x86-64 processor supports the IEEE floating-point format.
