# This file describes all the various CPUs, FPUs and architectures supported
# by the compiler. It is pre-processed by parsecpu.awk for a number of
# purposes.
#
# The general form is a sequence of begin..end blocks with the following
# syntax:
# begin
# attribute-statement*
# end
#
# where object type is one of "cpu" "arch" "fpu". Each object type has
# a specific set of permitted attributes, some of which are optional; further
# details can be found below.
#
# Some objects cross-reference other objects by name. Objects are permitted
# in any order and it is not necessary to place a cross-referenced object
# earlier in the file.
#
# The object names for cpu, arch and fpu objects are used for the public option
# names in the final compiler. The order within each group is preserved and
# forms the order for the list within the compiler.
