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.
 
NOTE >> The AMD x86-64 processor supports the IEEE floating-point format.
