x86-64 instruction set differs from IA-64. You can find information on former on AMD web site, e.g. http://www.amd.com:7246/us-en/Processors/DevelopWithAMD/0,,30_2252_875,00.html You can find information on later (including tutorials and reference) on Intel web site, e.g. http://developer.intel.com/design/itanium/ Eugene On September 14, 2001 at 16:00:12, Dann Corbit wrote: >On September 14, 2001 at 15:54:40, K.
