+
+  7.8.02 Goetz
+  Implemented scc algorithm.  Added datastructure to mark
+  backedges (ana/backedge.h) and to represent loops
+  (ana/irloop.h).  The scc algorithm (ana/irscc.c) builds
+  both datastructures.
+  The algorithm does not yet work properly for interprocedural
+  graphs.  Finds more loops than only recursions.
+
+  Improved place_code: now moves nodes out of loops.
+  Fixed bug in iropt.c:  wrong parameter in debug info: iropt_dbg.c
+  Now flag set_opt_control_flow can be set to 1 again.
+
+  11.7.2002 Goetz
+  Viele Aenderungen,
+  u.a. Zugrffsfkt normalisiert,
+  global, frame type nicht mehr in irp_types
+  interproz darstellung
+  mehr Zugriffsfkt bei entitaeten
+  u.v.a.
+
+  25.4.2002 Goetz
+  Added several constructors to tv.
+  Changed xgprintf so that full precision of double tvs is printed.
+  Fixed bug in irouts.c.
+
+  22.4.2002 Goetz
+  Added debug support, renamed stuff in ir/debug.
+  Optimizations still loose debug information.
+
+  19.3.2002 Goetz
+  Added flag "peculiarity" to entity.h, type.h.
+
+  15.3. Goetz
+  Bug: dominator construction aborts for BreakTest with flag 3.31
+  Problem: optimization of many subsequent blocks (Jmp-chains)
+  where one is inlined (Tuple control flow) in a loop.  Not all
+  nodes in merged blocks are moved to remaining block.
+  Fix:  different calling order to optimize_in_place_2 from
+  optimize_in_place_wrapper.
+  Bug: dumping cfg when a block is Bad.  Fix: Output Bad node.
+  Change: not only turn off cse but all optimizations during
+  inlining.
+
+  15.3. Goetz
+  Parted common.h into two files common_t.h.  By this config.h
+  as well as the preprocessor flags are no more visible externaly.
+  Adapted include directives.
+
+  12.3. Goetz
+  Bugfix in inlining: problems in combination with cse.
+
+  8.3. Goetz
+  Implemented cf optimizations.
+  Checked compiler flags -- sorted better to fit optimizations.
+
+  4.3. Goetz
+  Bugfix in irdom.
+  Implemented code placement.
+
+  28.2	Goetz
+  block walk in irouts.
+  irdom implemented: dominator information.
+
+  25.2. Goetz
+  Bugfix Optmierung Binops mit mode Tupel.
+
+  22.2. Goetz
+  irgopt: inline_small_irgs implemented
+
+  30.1. - 20.2. Goetz
+  Bugfixes, some access functions ...
+
+  29.1.2002 Goetz
+  New directory: ana for analyses.  Adapted configure/makefiles
+  implemented irout: backedges.  Added one field to ir_graph, one to ir_node.
+  Implemented state management for irgraphs:  see irgraph.h.
+  Must now call finalize_cons() after graph construction!!
+
+  24.1.2002 Goetz
+  Procedure global cse.
+  Flag pinned in irop, irgraph.
+  Global cse in irop, setting the irgraph flag.
+  Example programs: Endless_loop.c. global_cse.c.
+  Adapted irdump.
+
+  23.1.2002 Goetz
+  Implemented support for endless loops:
+  Adapted End node.
+  Adapted Phi constructors so that memory phis are added.
+  Adapted Cond optimization: add block to End.
+  Adapted dead node elimination: compation of Ends predecessors
+  Adapted inlineing:  remember keepalives of inlined graph.
+  Added informative strings to asserts in irvrfy.
+
+  21.1.2002 Goetz
+  Added volatile flag to entity, order flag to array.
+  Added a set of assertions.
+
+  17.1.2002 Goetz
+  Added access function set_class_members()
+
+  21.12.2001 Goetz
+  Asserts in irvrfy that verify the mode of Proj nodes.  For Start,
+  Call, Return they check the corresponding function type!  Corrected
+  bugs in testprograms.
+  Some asserts for legal values of 'pos' arguments in type/entity
+  access routines.
+
+  20.12.2001 Goetz
+  Some access routines for visited flags in entity.h, irnode.h,
+  bug in oo_program_example.
+
+  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.

   Added an Id tag to every .c and .h file
