*
- * NOTES
* This file documents all datatypes and constructors needed to
* build a FIRM representation of a pocedure. The constructors are
* also implemented in this file.
*
* For extensive documentation of FIRM see UKA Techreport 1999-14.
*
- * DATATYPES
* =========
*
* The struct ir_graph
* ------------------
* Not yet documented. See irmode.h.
*
- * GLOBAL VARIABLES
+ * GLOBAL VARIABLES -- now also fields of ir_graph.
* ================
*
* current_ir_graph Points to the current ir_graph. All constructors for

*
*
- * CONSTRUCTOR FOR IR_GRAPH
+ * CONSTRUCTOR FOR IR_GRAPH --> see irgraph.h
* ========================
*
- * ir_graph *new_ir_graph (entity *ent, int params);
- * -------------------------------------------------
- *
- * This constructor generates the basic infrastructure needed to
- * represent a procedure in FIRM.
- *
- * The parameters of new_ir_graph are:
- *
- * *ent A pointer to an entity representing the procedure.
- *
- * params An integer giving the number of local variables in the
- * procedure.
- *
- * It allocates an ir_graph and sets current_ir_graph to point to this
- * graph. Further it allocates the following nodes needed for every
- * procedure:
*
- * * The start block containing a start node and Proj nodes for it's
- * five results (X, M, P, P, T).
- * * The end block containing an end node. This block is not matured
- * after executing new_ir_graph as predecessors need to be added to it.
- * (Maturing a block means fixing it's number of predecessors.)
- * * The current block, which is empty and also not matured.
- *
- * Further it enters the global store into the datastructure of the start
- * block that contanis all valid values in this block (set_store()). This
- * datastructure is used to build the Phi nodes and removed after completion
- * of the graph.
- * There is no path from end to start in the graph after calling ir_graph.
- *
- *
- * PROCEDURE TO CONSTRUCT AN IR GRAPH
+ * PROCEDURE TO CONSTRUCT AN IR GRAPH --> see also Firm tutorial
* ==================================
*
* This library supplies several interfaces to construct a FIRM graph for
* To use the functionality of the comfortable interface correctly the Front
* End needs to follow certain protocols. This is explained in the following.
* To build a correct IR with the other interfaces study the semantics of
- * the firm node (See tech-reprot UKA 1999-44). For the construction of
+ * the firm node (See tech-reprot UKA 1999-14). For the construction of
* types and entities see the documentation in those modules.
*
* First the Frontend needs to decide which variables and values used in
* a procedure can be represented by dataflow edges. These are variables
* that need not be saved to memory as they cause no side effects visible
- * out of the procedure. In general these are all compiler generated
+ * out of the procedure. Often these are all compiler generated
* variables and simple local variables of the procedure as integers,
* reals and pointers. The frontend has to count and number these variables.
*
* add_in_edge(this_block, cf_pred1);
* add_in_edge(this_block, cf_pred2);
* mature_block(this_block);
- * a_val = get_value(17, mode_I);
+ * a_val = get_value(42, mode_Iu);
* mem = get_store();
* div = new_Div(mem, a_val, a_val);
* mem = new_Proj(div, mode_M, 0); * for the numbers for Proj see docu *
- * res = new_Proj(div, mode_I, 2);
+ * res = new_Proj(div, mode_Iu, 2);
* set_store(mem);
- * set_value(res, 17);
+ * set_value(res, 42);
* cf_op = new_Jmp();
*
* For further information look at the documentation of the nodes and
* ir_node *new_simpleSel (ir_node *store, ir_node *objptr, entity *ent);
* ir_node *new_Sel (ir_node *store, ir_node *objptr, int arity,
* ir_node **in, entity *ent);
+ * ir_node *new_InstOf (ir_node *store, ir_node *objptr, type *ent);
* ir_node *new_Call (ir_node *store, ir_node *callee, int arity,
* ir_node **in, type_method *type);
* ir_node *new_Add (ir_node *op1, ir_node *op2, ir_mode *mode);
* void set_value (int pos, ir_node *value);

*
* IR_NODES AND CONSTRUCTORS FOR IR_NODES
* =======================================
* - the outputs of the Firm node
* - attributes to the node
*
- * BASIC BLOCKS
* ------------
*
* ir_node *new_immBlock (void)
*
* get_value(loop_body, x); // gets the Phi in loop_header
* set_value(loop_header, x); // sets the value the above get_value should
- * // have returned!!!
+ * // have returned!!!
*
* Mature_block also fixes the number of inputs to the Phi nodes. Mature_block
* should be called as early as possible, as afterwards the generation of Phi
* else it points to the end_block.
*
*
- * CONSTANTS
* ---------
*
* ir_node *new_Const (ir_mode *mode, tarval *con)
* attr.con A tarval* pointer to the proper entry in the constant
* table.
*
- * ir_node *new_SymConst (type *type, symconst_kind kind)
+ * ir_node *new_SymConst (type *tp, symconst_kind kind)
* ------------------------------------------------------------
*
* There are three kinds of symbolic constants:
* size The symbolic constant represents the size of a class.
* link_info Information for the linker, e.g. the name of a global
* variable.
+ * To represent a pointer to an entity that is represented by an entity
+ * datastructure don't use
+ * new_SymConst((type_or_id*)get_entity_ld_ident(ent), linkage_ptr_info);.
+ * Use a real const instead:
+ * new_Const(mode_P, tarval_p_from_entity(ent));
+ * This makes the Constant independent of name changes of the entity due to
+ * mangling.
*
* Parameters
* kind The kind of the symbolic constant: type_tag, size or link_info.
* - size
* - linkage_ptr_info
* If the attr.i.num is type_tag or size, the node contains an attribute
- * attr.i.*type, a pointer to a type_class. The mode of the node is mode_i.
+ * attr.i.*type, a pointer to a type_class. The mode of the node is mode_Is.
* if it is linkage_ptr_info it contains
* attr.i.*ptrinfo, an ident holding information for the linker. The mode
- * of the node is mode_p.
+ * of the node is mode_P.
*
- * THE SELECT NODE
* ---------------
*
* ir_node *new_simpleSel (ir_node *store, ir_node *frame, entity *sel)
* ir_node *new_Minus (ir_node *op, ir_mode *mode)
* -----------------------------------------------
*
- * This constructor is for unary Minus operations on floating point
- * values. Such a Minus can trap if it is implemented as a Sub from
- * zero due to rounding errors.
+ * Unary Minus operations on floating point values.
*
* ir_node *new_Mul (ir_node *op1, ir_node *op2, ir_mode *mode)
* ------------------------------------------------------------
*
*
*
- * THE PHI NODE
* ------------
*
* In general, Phi nodes are automaitcally inserted. In some cases, if
* adds the value to the array of used values at position pos. Pos
* has to be a unique identifier for an entry in the procedure's
* definition table. It can be used to access the value again.
+ * Requires current_block to be set correctly.
*
* ir_node *get_value (int pos, ir_mode *mode)
* -------------------------------------------
* definition reaches the currend block on several different
* paths. This Phi node will be eliminated if optimizations are
* turned on right after it's creation.
- *
+ * Requires current_block to be set correctly.
*
* There are two special routines for the global store:
*
*
* Adds the store to the array of known values at a reserved
* position.
+ * Requires current_block to be set correctly.
*
* inline ir_node *get_store (void)
* --------------------------------
*
* Returns the node defining the actual store.
- *****
+ * Requires current_block to be set correctly.
+ *
+ *
+ * inline void keep_alive (ir_node *ka)
+ * ------------------------------------
+ *
+ * Keep this node alive because it is (might be) not in the control
+ * flow from Start to End. Adds the node to the list in the end
+ * node.
