# 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", # optional
-# irn_flags => "R|N|I" # optional
# arity => "0|1|2|3 ... |variable|dynamic|any", # optional
# state => "floats|pinned|mem_pinned|exc_pinned", # optional
# args => [
#
# ); # 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
-#
-# irn_flags: special node flags, OPTIONAL (default is 0)
-# following irn_flags are supported:
-# 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
#
# 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 - 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)
+# 1 - ignore (do not assign this register)
+# 2 - emitter can choose an arbitrary register of this class
+# 4 - the register is a virtual one
+# 8 - register represents a state
# NOTE: Last entry of each class is the largest Firm-Mode a register can hold
