8# for. It can only be ia64 at this time.

12# directive: cpu
13# You must specify at least one CPU (the one you intend to run on). Deleting
14# the support for CPUs you don't need to use may make parts of the system run
15# faster. There's currently no special code for the different CPUs. Note also
16# that the cpu declares the family. We may need to add support for specifying
17# particular models.
18cpu		ITANIUM

21# option: IA32
22# This option enables the support for execution of i386 (32-bit) programs on
23# ia64. It is based on the ia32 emulation in the processor.
