-# 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|any",
-# "state" => "floats|pinned|mem_pinned|exc_pinned",
-# "args" => [
-# { "type" => "type 1", "name" => "name 1" },
-# { "type" => "type 2", "name" => "name 2" },
-# ...
-# ],
-# comment => "any comment for constructor",
-# reg_req => { in => [ "reg_class|register" ], out => [ "reg_class|register|in_rX" ] },
-# cmp_attr => "c source code for comparing node attributes",
-# outs => { "out1", "out2" } # optional, creates pn_op_out1, ... consts
-# ins => { "in1", "in2" } # optional, creates n_op_in1, ... consts
-# mode => "mode_Iu" # optional, predefines the mode
-# emit => "emit code with templates",
-# attr => "attitional attribute arguments for constructor",
-# init_attr => "emit attribute initialization template",
-# rd_constructor => "c source code which constructs an ir_node",
-# hash_func => "name of the hash function for this operation",
-# latency => "latency of this operation (can be float)"
-# attr_type => "name of the attribute struct",
-# },
-#
-# ... # (all nodes you need to describe)
-#
-# ); # close the %nodes initializer
-
-# op_flags: flags for the operation, OPTIONAL (default is "N")
-# 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
-#
-# R rematerializeable
-# N not spillable
-# I ignore for register allocation
-#
-# state: state of the operation, OPTIONAL (default is "floats")
-#
-# 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
-#
-# outs: if a node defines more than one output, the names of the projections
-# nodes having outs having automatically the mode mode_T
-#
-# 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
