3 # This is the specification for the ia32 assembler Firm-operations
10 # the cpu architecture (ia32, ia64, mips, sparc, ppc, ...)
13 # The node description is done as a perl hash initializer with the
14 # following structure:
19 # op_flags => "N|L|C|X|I|F|Y|H|c|K",
20 # irn_flags => "R|N|I|S"
21 # arity => "0|1|2|3 ... |variable|dynamic|any",
22 # state => "floats|pinned|mem_pinned|exc_pinned",
24 # { type => "type 1", name => "name 1" },
25 # { type => "type 2", name => "name 2" },
28 # comment => "any comment for constructor",
29 # reg_req => { in => [ "reg_class|register" ], out => [ "reg_class|register|in_rX" ] },
30 # cmp_attr => "c source code for comparing node attributes",
31 # emit => "emit code with templates",
32 # attr => "attitional attribute arguments for constructor"
33 # init_attr => "emit attribute initialization template"
34 # rd_constructor => "c source code which constructs an ir_node"
35 # latency => "latency of this operation (can be float)"
38 # ... # (all nodes you need to describe)
40 # ); # close the %nodes initializer
42 # op_flags: flags for the operation, OPTIONAL (default is "N")
43 # the op_flags correspond to the firm irop_flags:
46 # C irop_flag_commutative
47 # X irop_flag_cfopcode
48 # I irop_flag_ip_cfopcode
51 # H irop_flag_highlevel
52 # c irop_flag_constlike
55 # irn_flags: special node flags, OPTIONAL (default is 0)
56 # following irn_flags are supported:
59 # I ignore for register allocation
60 # S modifies stack pointer
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
75 # One can also annotate some flags for each out, additional to irn_flags.
76 # They are separated from name with a colon ':', and concatenated by pipe '|'
77 # Only I and S are available at the moment (same meaning as in irn_flags).
78 # example: [ "frame:I", "stack:I|S", "M" ]
80 # comment: OPTIONAL comment for the node constructor
82 # rd_constructor: for every operation there will be a
83 # new_rd_<arch>_<op-name> function with the arguments from above
84 # which creates the ir_node corresponding to the defined operation
85 # you can either put the complete source code of this function here
87 # This key is OPTIONAL. If omitted, the following constructor will
89 # if (!op_<arch>_<op-name>) assert(0);
93 # res = new_ir_node(db, irg, block, op_<arch>_<op-name>, mode, arity, in)
96 # NOTE: rd_constructor and args are only optional if and only if arity is 0,1,2 or 3
98 # latency: the latency of the operation, default is 1
102 # 0 - no special type
103 # 1 - caller save (register must be saved by the caller of a function)
104 # 2 - callee save (register must be saved by the called function)
105 # 4 - ignore (do not assign this register)
106 # 8 - emitter can choose an arbitrary register of this class
107 # 16 - the register is a virtual one
108 # 32 - register represents a state
109 # NOTE: Last entry of each class is the largest Firm-Mode a register can hold
