10 ** - A list of all procedures.
11 ** - A list of all types.
12 ** - A global type that can be thought of as a god-class containing all
13 ** global variables and procedures. This is not the base class of
14 ** all classes in a class hierarchy (as, e.g., "object" in java).
15 ** - (An obstack containing global things, e.g., the above mentioned lists.)
26 * NAME Datastructure that holds central information about a program
28 * NOTE Preliminary documentation ;-)
35 * NAME Datastructure that holds central information about a program
37 * NOTE Preliminary documentation ;-)
40 * main_irg The ir graph that is the entry point to the program.
41 * (Anything not reachable from here may be optimized away.
42 * If we want to translate libraries or the like correctly
43 * we must replace this by a list.)
44 * irg List of all ir graphs in the program.
45 * type A list containing all types known to the translated program.
46 * Some types can have several entries in this list (as a result of
47 * using exchange_types()).
48 * glob_type The unique global type that is owner of all global entities.
