It defines the architecture to be configured 8162271Srwatson# for. It can only be ia64 at this time. 9162271Srwatson# 10162271Srwatsonmachine ia64 11162271Srwatson 12162271Srwatson# directive: cpu 13162271Srwatson# You must specify at least one CPU (the one you intend to run on). Deleting 14162271Srwatson# the support for CPUs you don't need to use may make parts of the system run 15162271Srwatson# faster. There's currently no special code for the different CPUs. Note also 16162271Srwatson# that the cpu declares the family. We may need to add support for specifying 17162271Srwatson# particular models. 18162271Srwatsoncpu ITANIUM 19162271Srwatsoncpu ITANIUM2 20162271Srwatson 21162271Srwatson# option: IA32 22162271Srwatson# This option enables the support for execution of i386 (32-bit) programs on 23162271Srwatson# ia64.
