+
+# The node description is done as a perl hash initializer with the
+# following structure:
+#
+# %nodes = (
+#
+# <op-name> => {
+# "op_flags" => "N|L|C|X|I|F|Y|H|c|K",
+# "arity" => "0|1|2|3|variable|dynamic|all",
+# "state" => "floats|pinned",
+# "args" => [
+# { "type" => "type 1", "name" => "name 1" },
+# { "type" => "type 2", "name" => "name 2" },
+# ...
+# ],
+# "comment" => "any comment for constructor",
+# "rd_constructor" => "c source code which constructs an ir_node"
+# },
+#
+# ... # (all nodes you need to describe)
+#
+# ); # close the %nodes initializer
+
+# the op_flags correspond to the firm irop_flags:
+# N irop_flag_none
+# L irop_flag_labeled
+# C irop_flag_commutative
+# X irop_flag_cfopcode
+# I irop_flag_ip_cfopcode
+# F irop_flag_fragile
+# Y irop_flag_forking
+# H irop_flag_highlevel
+# c irop_flag_constlike
+# K irop_flag_keep
+#
+# op_flags: flags for the operation, OPTIONAL (default is "N")
+#
+# state: state of the operation, OPTIONAL (default is "pinned")
+#
+# arity: arity of the operation, MUST NOT BE OMITTED
+#
+# args: the OPTIONAL arguments of the node constructor (debug, irg and block
+# are always the first 3 arguments and are always autmatically
+# created)
+# If this key is missing the following arguments will be created:
+# for i = 1 .. arity: ir_node *op_i
+# ir_mode *mode
+#
+# comment: OPTIONAL comment for the node constructor
+#
+# rd_constructor: for every operation there will be a
+# new_rd_<arch>_<op-name> function with the arguments from above
+# which creates the ir_node corresponding to the defined operation
+# you can either put the complete source code of this function here
+#
+# This key is OPTIONAL. If omitted, the following constructor will
+# be created:
+# if (!op_<arch>_<op-name>) assert(0);
+# for i = 1 to arity
+# set in[i] = op_i
+# done
+# res = new_ir_node(db, irg, block, op_<arch>_<op-name>, mode, arity, in)
+# return res
+#
+# NOTE: rd_constructor and args are only optional if and only if arity is 0,1,2 or 3
+
+# register types:
+# 0 - no special type
+# 1 - write invariant (writes to this register doesn't change it's content)
+# 2 - caller save (register must be saved by the caller of a function)
+# 3 - callee save (register must be saved by the called function)
+# 4 - ignore (do not assign this register)
+# NOTE: Make sure to list the registers returning the call-result before all other
+# caller save registers and in the correct order, otherwise it will break
+# the magic!
