+
+  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.
