9 # the cpu architecture (ia32, ia64, mips, sparc, ppc, ...)
12 # The node description is done as a perl hash initializer with the
13 # following structure:
18 # op_flags => "N|L|C|X|I|F|Y|H|c|K|n",
20 # arity => "0|1|2|3 ... |variable|dynamic|any",
21 # state => "floats|pinned|mem_pinned|exc_pinned",
23 # { type => "type 1", name => "name 1" },
24 # { type => "type 2", name => "name 2" },
27 # comment => "any comment for constructor",
28 # reg_req => { in => [ "reg_class|register" ], out => [ "reg_class|register|in_rX" ] },
29 # cmp_attr => "c source code for comparing node attributes",
30 # outs => { "out1", "out2" } # optional, creates pn_op_out1, ... consts
31 # ins => { "in1", "in2" } # optional, creates n_op_in1, ... consts
32 # mode => "mode_Iu" # optional, predefines the mode
33 # emit => "emit code with templates",
34 # attr => "additional attribute arguments for constructor",
35 # init_attr => "emit attribute initialization template",
36 # hash_func => "name of the hash function for this operation",
37 # latency => "latency of this operation (can be float)"
38 # attr_type => "name of the attribute struct",
39 # modified_flags => [ "CF", ... ] # optional, list of modified flags
42 # ... # (all nodes you need to describe)
44 # ); # close the %nodes initializer
46 # op_flags: flags for the operation, OPTIONAL (default is "N")
47 # the op_flags correspond to the firm irop_flags:
50 # C irop_flag_commutative
51 # X irop_flag_cfopcode
52 # I irop_flag_ip_cfopcode
55 # H irop_flag_highlevel
56 # c irop_flag_constlike
58 # NB irop_flag_dump_noblock
59 # NI irop_flag_dump_noinput
61 # irn_flags: special node flags, OPTIONAL (default is 0)
62 # following irn_flags are supported:
66 # state: state of the operation, OPTIONAL (default is "floats")
68 # arity: arity of the operation, MUST NOT BE OMITTED
70 # args: the OPTIONAL arguments of the node constructor (debug, irg and block
71 # are always the first 3 arguments and are always autmatically
73 # If this key is missing the following arguments will be created:
74 # for i = 1 .. arity: ir_node *op_i
77 # outs: if a node defines more than one output, the names of the projections
78 # nodes having outs having automatically the mode mode_T
79 # example: [ "frame", "stack", "M" ]
81 # comment: OPTIONAL comment for the node constructor
83 # rd_constructor: for every operation there will be a
84 # new_rd_<arch>_<op-name> function with the arguments from above
85 # which creates the ir_node corresponding to the defined operation
86 # you can either put the complete source code of this function here
88 # This key is OPTIONAL. If omitted, the following constructor will
90 # if (!op_<arch>_<op-name>) assert(0);
94 # res = new_ir_node(db, irg, block, op_<arch>_<op-name>, mode, arity, in)
97 # NOTE: rd_constructor and args are only optional if and only if arity is 0,1,2 or 3
101 # 0 - no special type
102 # 1 - caller save (register must be saved by the caller of a function)
103 # 2 - callee save (register must be saved by the called function)
104 # 4 - ignore (do not automatically assign this register)
105 # 8 - emitter can choose an arbitrary register of this class
106 # 16 - the register is a virtual one
107 # 32 - register represents a state
108 # NOTE: Last entry of each class is the largest Firm-Mode a register can hold
