# The node description is done as a perl hash initializer with the
# following structure:
# comment: OPTIONAL comment for the node constructor
#
# register types:
-# 0 - no special type
-# 1 - caller save (register must be saved by the caller of a function)
-# 2 - callee save (register must be saved by the called function)
-# 4 - ignore (do not assign this register)
+# none - no special type
+# ignore - ignore (do not assign this register)
+# virtual - the register is a virtual one
+# state - register represents a state
# NOTE: Last entry of each class is the largest Firm-Mode a register can hold
