16 # irn_flags => "R|N|I" # optional
17 # arity => "0|1|2|3 ... |variable|dynamic|any", # optional

25 # reg_req => { in => [ "reg_class|register" ], out => [ "reg_class|register|in_rX" ] },
26 # cmp_attr => "c source code for comparing node attributes", # optional
27 # outs => { "out1", "out2" },# optional, creates pn_op_out1, ... consts
28 # ins => { "in1", "in2" }, # optional, creates n_op_in1, ... consts
29 # mode => "mode_Iu", # optional, predefines the mode
30 # emit => "emit code with templates", # optional for virtual nodes
31 # attr => "additional attribute arguments for constructor", # optional
32 # init_attr => "emit attribute initialization template", # optional
33 # rd_constructor => "c source code which constructs an ir_node", # optional
34 # hash_func => "name of the hash function for this operation", # optional, get the default hash function else
35 # latency => "latency of this operation (can be float)" # optional
36 # attr_type => "name of the attribute struct", # optional
39 # ... # (all nodes you need to describe)
41 # ); # close the %nodes initializer
43 # op_flags: flags for the operation, OPTIONAL (default is "N")
44 # the op_flags correspond to the firm irop_flags:
47 # C irop_flag_commutative
48 # X irop_flag_cfopcode
49 # I irop_flag_ip_cfopcode
52 # H irop_flag_highlevel
53 # c irop_flag_constlike
56 # irn_flags: special node flags, OPTIONAL (default is 0)
57 # following irn_flags are supported:
60 # I ignore for register allocation
62 # state: state of the operation, OPTIONAL (default is "floats")
64 # arity: arity of the operation, MUST NOT BE OMITTED
66 # args: the OPTIONAL arguments of the node constructor (debug, irg and block
67 # are always the first 3 arguments and are always autmatically
69 # If this key is missing the following arguments will be created:
70 # for i = 1 .. arity: ir_node *op_i
73 # outs: if a node defines more than one output, the names of the projections
74 # nodes having outs having automatically the mode mode_T
76 # comment: OPTIONAL comment for the node constructor
78 # rd_constructor: for every operation there will be a
79 # new_rd_<arch>_<op-name> function with the arguments from above
80 # which creates the ir_node corresponding to the defined operation
81 # you can either put the complete source code of this function here
83 # This key is OPTIONAL. If omitted, the following constructor will
85 # if (!op_<arch>_<op-name>) assert(0);
89 # res = new_ir_node(db, irg, block, op_<arch>_<op-name>, mode, arity, in)
92 # NOTE: rd_constructor and args are only optional if and only if arity is 0,1,2 or 3
96 # 1 - caller save (register must be saved by the caller of a function)
97 # 2 - callee save (register must be saved by the called function)
98 # 4 - ignore (do not assign this register)
99 # NOTE: Last entry of each class is the largest Firm-Mode a register can hold
