+  7.7.2000 Chris
+  Fixed some bugs in irgopt.c
+  Added some missing 'get_new_node' methods, so the new obstack contains
+  the correct nodes.
+
+  6.7.2000 Chris
+  Renamed ir_vrfy to irn_vrfy and vrfy_graphg to irg_vrfy.
+  Solved some copy'n'paste problems. Deleted most debug-code!
+  Added comments to several files.
+
+  6.7.2000 Goetz
+  Fixed bug in _r_ constructors for all four Div operations.
+  Fixed bug in turn_into_tuple: didn't remember the block.
+  Tested transform_node.
+
   5.7.2000 Goetz
+  Fixed some testprograms to new semantics of firm.
+  Added testprogram global_var_example.
+  Fixed a bug in irop:  Size of Sel node was (entity *) instead of
+  sel_attr.  Therefor array_heap_example aborted.
+  Also found a missing break in typewalk, case iro_Alloc.
+  Added a construct that unifies all things constructed by the lib
+  and needed to represent a program:  irprog.ch
+  This contains a list of all types as well as a list of all ir graphs.
+  I added calls to initialization and constructors so that this is constructed
+  automatically.  I changed firm.c, type.c, irgraph.c and ev. more.
   Removed strange block struct and constructor from ircons.c.
   Moved routines for automatic Phi construction from irgmod to ircons.
   Sorted functions in ircons to reflect the different interfaces.

   4.7.2000 Goetz
   Commented a whole bunch of stuff, e.g. in ircons.h  (Procedure to construct)
   We should change the naming of the Block constructor.

-  4.7.2000 Goetz
   Removed acces routines to attr. "closed" of Block.
-
-  4.7.2000 Goetz
   Removed second implementation of new_ir_node from ircons and some comments
   concerned with the now resolved cyclic dependency.
   Fixed some bugs in irgopt so that the compilation goes through.
 
+  29.6.2000 Chris
+  Changed the irnode attribut 'visit' into 'visited'.
+  Added some access functions, like get/set_irn_visit etc.
+
+  28.6.2000 Chris
+  Renamed some access funtion in irgraph.*.
+  Deleted two global flags (ir_visited and block_visited) from irgraph.*.
+  Added two attributes to the irgraph struct. The visited flags belongs
+  to a ir graph, not to a whole program.
+
+  26.6.2000 Chris
+  A new optimization has been finished. The dead-node-elimination copies
+  the existing ir graph from one opstack to another. While walking the
+  graph, only the reachable nodes will be copied, so the "dead-nodes"
+  (unreachable in the controlflow) are removed.
+
+  19.6.2000 Chris
+  Solved some problems in the 'copy_node' function. The in array was not
+  as easy as it seamed.
+
+  16.6.2000 Chris
+  Wrote a new 'post' funtion, for future use in 'dead-node-elimination'
+  optimization, which is needed in the paramter list of 'irg_walk'.
+
+  14.6.2000 Chris
+  Moved 'optimze_in_place_wrapper' from iropt.* tothe new files irgopt.*.
+  New functions 'local_optimze_graph' and 'dead_node_elimination' are added,
+  but not finished.

   31.5.2000 Chris
   Removed some files from the archive, after dependencies and usage are
   checked:
