# 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 <object-type> <name>
#  attribute-statement*
# end <object-type> <name>
#
# 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.

# Most objects in this file support forward references.  The major
# exception is feature groups, which may only refer to previously
# defined features or feature groups.  This is done to avoid the risk
# of feature groups recursively referencing each other and causing
# the parser to hang.

# Features - general convention: all lower case.
