Intel's MMX Instruction Set

|  Overview |  How Do I

The Visual C++ compiler allows you to use Intel's MMX (multimedia extension) instruction set in the inline assembler. The MMX instructions are also supported by the debugger disassembly. The MMX registers are not supported in the debugger register window. The compiler generates a warning message if the function contains MMX instructions, but does not have an EMMS instruction to empty the multimedia state. For more information, see the Intel Web site.
