- 12.1.2001 Goetz
+ 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.
