AMD and Intel x86-64

This section describes AMD's 64-bit processors and the Intel EM64T processoers. It contains the following information:

“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.
