16 * Central FIRM header.
18 * FIRM is a full graph based intermediate representation in SSA Form
19 * with a novel concept to model side effects. It allows fast, aggressive
22 * This header is the central header of the library implementation of this
25 * The internal representation of a program in firm is separated into five
27 * - Firm Graphs representing the code of a program. (Subdirectory ir.)
28 * Firm Graphs are assembled out of several data structures:
29 * irprog: represents a program. Allows access to all types and all
30 * FIRM graphs for procedures and other global things.
31 * irgraph: represents a procedure. Allows access to the code of the
32 * procedure, the actual FIRM graph.
33 * irnode: A node of a FIRM graph. Nodes are typed with an opcode and a mode
34 * and represent instructions in a program.
35 * irop: The opcode of FIRM nodes.
36 * irmode: The mode of FIRM nodes. Most modes correspond to machine known
37 * data types (int, float, pointer).
38 * - Entities representing program known objects. (Subdirectory tr.)
39 * All variables and procedures are entities.
40 * - Types describing the type system for the program. (Subdirectory tr.)
41 * - Target Values representing program known constants. (Subdirectory tv.)
42 * - Identifiers representing any Strings used in the program. (Subdirectory ident.)
44 * Further this library supplies functionality to build and optimize FIRM graphs
45 * and further functionality needed in a compiler. Finally there is more
46 * generic functionality to support implementations using firm. (Code generation,
47 * further optimizations).
