+ 29.8.2001 Goetz
+ Added routine to free irgraphs.
+
+ 17.7.2001 Goetz
+ Improved add routines to sub, supertype in type.c
+
+ 12.r7.2001 Goetz
+ Added implementation of overwrites stuff.
+
+ 11.7.2001 Goetz
+ Implemented stuff to change the type graph. See
+ typegmod.h and tpop.h for basic documentation of the change.
+ There now exists a type of kind type_id. If this appears
+ externally this is a bug.
+
+ 9.7.2001 Goetz
+ Added some new access routines to types.
+ List of overwritten fields for entities.
+ Removed a bug in irnode.
+
+ 4.7.2001 Goetz
+ Added a routine to set the mangled entity name.
+ Added two routines to copy entites.
+
+ 3.7.2001 Goetz
+ Entities now have two more flags, for visibility and allocation mode.
+ Types that have a layout have a flag indicating whether the layout is
+ fixed.
+
+ 25.6.2001 Goetz
+ We distinguish three kinds of Cond nodes. These can be distinguished
+ by the mode of the selector operand and an internal flag of type cond_kind.
+ First we distinguish binary Conds and switch Conds.
+ A binary Cond has as selector a boolean value. Proj(0) projects the control
+ flow for case "False", Proj(1) the control flow for "True". A binary Cond
+ is recognized by the boolean selector.
+ The switch Cond has as selector an unsigned integer. It produces as result
+ an n+1 Tuple (cf0, ... , cfn) of control flows.
+ We differ two flavours of this Cond. The first, the dense Cond, passes
+ control along output i if the selector value is i, 0 <= i <= n. If the
+ selector value is >n it passes control along output n.
+ The second Cond flavor differes in the treatment of cases not specified in
+ the source program. It magically knows about the existence of Proj nodes.
+ It only passes control along output i, 0 <= i <= n, if a node Proj(Cond, i)
+ exists. Else it passes control along output n (even if this Proj does not
+ exist.) This Cond we call "fragmentary". There is a special constructor
+ new_defaultProj that automatically sets the flavor.
+ The two switch flavors are distinguished by a flag of type cond_kind.
+ Default flavor is "dense"

+ 20.6.2001 Goetz
+ Extended iropt, tv.
+ tv now implements Minus, Abs.
+ iropt now optimizes these and Div, Mod, Quot, DivMod.
+ Still missing: Shrs, Rot.
+ tarval_shr somtimes performs shrs, depending on the compiler/system!!
+ If the ArmRoq implementation is faulty there might appear errors.
+
+ 20.6.2001 Goetz
+ Changed ircons: If undefined values are used the Phi construction
+ inserts a constant with value tarval_bad.
+
+ 19.6.2001 Goetz
+ Changed array bounds in type.h to ir_node*. This allows to
+ construct array bounds that are complex constant expressions
+ simpler. Further dynamic array bounds can be displayed.
+ Comment in ircons.c extended: undefined values in start_block.
+
+ 7.6.2001 Goetz
+ ifdef'ed all uses of gmp in tv.c away. Optimizations for
+ mode_Z no more supported, as well as constants of that mode.
+
+ 7.6.2001 Goetz
+ Dokumentation in ir_dump
+ Habe Routinen fuer einzelne Knoten/Kanten aus header entfernt:
+ Benutzen globale Variable die nicht oeffentlich zugaenglich ist.
