31 # ... # (all nodes you need to describe)
33 # ); # close the %nodes initializer
35 # op_flags: flags for the operation, OPTIONAL (default is "N")
36 # the op_flags correspond to the firm irop_flags:
39 # C irop_flag_commutative

41 # I irop_flag_ip_cfopcode
44 # H irop_flag_highlevel
45 # c irop_flag_constlike
48 # irn_flags: special node flags, OPTIONAL (default is 0)
49 # following irn_flags are supported:
52 # I ignore for register allocation
54 # state: state of the operation, OPTIONAL (default is "floats")
56 # arity: arity of the operation, MUST NOT BE OMITTED
58 # args: the OPTIONAL arguments of the node constructor (debug, irg and block
59 # are always the first 3 arguments and are always autmatically
61 # If this key is missing the following arguments will be created:
62 # for i = 1 .. arity: ir_node *op_i
65 # comment: OPTIONAL comment for the node constructor
67 # rd_constructor: for every operation there will be a
68 # new_rd_<arch>_<op-name> function with the arguments from above
69 # which creates the ir_node corresponding to the defined operation
70 # you can either put the complete source code of this function here
72 # This key is OPTIONAL. If omitted, the following constructor will
74 # if (!op_<arch>_<op-name>) assert(0);
78 # res = new_ir_node(db, irg, block, op_<arch>_<op-name>, mode, arity, in)
81 # NOTE: rd_constructor and args are only optional if and only if arity is 0,1,2 or 3
85 # 1 - caller save (register must be saved by the caller of a function)
86 # 2 - callee save (register must be saved by the called function)
87 # 4 - ignore (do not assign this register)
88 # NOTE: Last entry of each class is the largest Firm-Mode a register can hold
