DESCRIPTION
This enum gives the object file's CPU architecture, in a
- global sense. E.g. what processor family does it belong to?
- There is another field, which indicates what processor within
+ global sense---i.e., what processor family does it belong to?
+ Another field indicates which processor within
the family is in use. The machine gives a number which
- distingushes different versions of the architecture,
- containing for example 2 and 3 for Intel i960 KA and i960 KB,
- and 68020 and 68030 for Motorola 68020 and 68030.
