- *
- * The struct ir_graph
- * -------------------
- *
- * This struct contains all information about a procedure.
- * It's allocated directly to memory.
- *
- * The fields of ir_graph:
- *
- * *ent The entity describing this procedure.
- *
- * The beginning and end of a graph:
- *
- * *start_block This ir_node is the block that contains the unique
- * start node of the procedure. With it it contains
- * the Proj's on starts results.
- * Further all Const nodes are placed in the start block.
- * *start This ir_node is the unique start node of the procedure.
- *
- * *end_block This ir_node is the block that contains the unique
- * end node of the procedure. This block contains no
- * further nodes.
- * *end This ir_node is the unique end node of the procedure.
- *
- * The following nodes are Projs from the start node, held in ir_graph for
- * simple access:
- *
- * *frame The ir_node producing the pointer to the stack frame of
- * the procedure as output. This is the Proj node on the
- * third output of the start node. This output of the start
- * node is tagged as pns_frame_base. In FIRM most lokal
- * variables are modeled as data flow edges. Static
- * allocated arrays can not be represented as dataflow
- * edges. Therefore FIRM has to represent them in the stack
- * frame.
- *
- * *globals This models a pointer to a space in the memory where
- * _all_ global things are held. Select from this pointer
- * with a Sel node the pointer to a global variable /
- * procedure / compiler known function... .
- *
- * *args The ir_node that produces the arguments of the method as
- * it's result. This is a Proj node on the fourth output of
- * the start node. This output is tagged as pn_Start_T_args.
- *
- * *bad The bad node is an auxiliary node. It is needed only once,
- * so there is this globally reachable node.
- *
- * Datastructures that are private to a graph:
- *
- * *obst An obstack that contains all nodes.
- *
- * *current_block A pointer to the current block. Any node created with
- * one of the node constructors (new_<opcode>) are assigned
- * to this block. It can be set with set_cur_block(block).
- * Only needed for ir construction.
- *
- * params/n_loc An int giving the number of local variables in this
- * procedure. This is neede for ir construction. Name will
- * be changed.
- *
- * *value_table This hash table (pset) is used for global value numbering
- * for optimizing use in iropt.c.
- *
- * *Phi_in_stack; a stack needed for automatic Phi construction, needed only
- * during ir construction.
- *
- * visited A int used as flag to traverse the ir_graph.
- *
- * block_visited A int used as a flag to traverse block nodes in the graph.
*
* Three kinds of nodes
* --------------------
*
* This library supplies several interfaces to construct a FIRM graph for
* a program:
- * * A "comfortable" interface generating SSA automatically. Automatically
+ * - A "comfortable" interface generating SSA automatically. Automatically
* computed predecessors of nodes need not be specified in the constructors.
* (new_<Node> constructurs and a set of additional routines.)
- * * A less comfortable interface where all predecessors except the block
+ * - A less comfortable interface where all predecessors except the block
* an operation belongs to need to be specified. SSA must be constructed
* by hand. (new_<Node> constructors and set_cur_block()). This interface
* is called "block oriented". It automatically calles the local optimizations
* for each new node.
- * * An even less comfortable interface where the block needs to be specified
+ * - An even less comfortable interface where the block needs to be specified
* explicitly. This is called the "raw" interface. (new_r_<Node>
* constructors). These nodes are not optimized.
