+  17.12.2001 Boris
+  Removed all obsolete Makefiles
+
+  10.12.2001 Goetz
+  Added support for constant entities.  A new example program illustrates
+  their use.  Extended dumper routines to dump constant values.
+
+  30.11.2001 Goetz
+  Extendend "comfortable" construction interface by some methods
+  serving as simple shortcuts.
+
+  30.11.2001 Goetz
+  Added a class type to irgs.  This class type is to be used as owner
+  for local entities of the procedure. This are all entities allocated
+  for each execution of the procedure.
+  The class type is allocated automatically by new_ir_graph().  Access
+  routines to get this type are in irgraph.h.
+  We chose a class type as this allows to represent "inner" procedures
+  as, e.g., in Pascal.
+  Adapted array-stack-example.
+
+  29.11.2001 Goetz
+  irdump outputs nodeids instead of pointers for labels of nodes.
+  With a preprocessor flag in common.h this can be turned off.
+
+  28.11.2001 Boris
+  Added an Id tag to every .c and .h file
+
+  20.11.2001 Goetz
+  Changed SSA constuction for exception control flow.
+  If PRECISE_EXC_CONTEXT is used Phi nodes will use the values
+  valid when the execption operation was allocated.  This increases
+  the memory consuption of the construction algorithm by
+  n_loc * #fragile_ops.
+
+  19.11.2001 Goetz
+  Added method to replace in array of a node in irnode.c/h
+  Added functionality to irgmod:
+   * collect all Phi nodes as link-list in the Blocks link field
+   * collect all Proj nodes as link-list in node producing the tuple.
+   * Seperate a Block into two
+  Added inlining transformation in irgopt.h
+  Improved output of dump_ir_block_graph.  Now also dumps nodes that
+  don't belong to a block.
+  Added flag opt_unreachable_code, opt_inline.
+  Changed irvrfy so that it accepts nodes with Bad predecessors.
+
+  19.10.2001 Boris
+  renamed get_type_nameid to get_type_ident
+
+  10.9.2001 Goetz
+  Bugfix: dead node elimination did not replace the hash table
+  for cse.
+
+  29.8.2001 Goetz
+  Added routine remove_irp_irg.
+  Changed comment to free_ir_graph.
+
+  29.8.2001 Goetz
+  Added routine to free irgraphs.
+
+  17.7.2001 Goetz
+  Improved add routines to sub, supertype in type.c
+
+  12.7.2001 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.
