+ 6.9.00 Goetz
+ Added irdump routine dump_all_types.
+ Did changes to irprog, type, typewalk to achieve this.
+ typewalk needs to walk along members, sub and supertypes, this
+ is still missing! irdump then needs to output these edges.

+======================================================================
+==================== New version: 0.2.5 ==============================
+======================================================================
+
+ 3.9.00 Goetz
+ Made new Version: 0.2.5
+
+ 15.8.2000 Goetz until 3.9.00
+ Separated irnode.h and many others into two files: one public
+ one private.
+ Added funcionality to extract headers for lib.
+
+ 23.8.2000 Goetz
+ type_dump also dumps irg->ent
+ if_example: corrected nr of locals
+
+ 16.8.2000 Goetz
+ irgopt: Correct copy of self pointer in start block.
+ irgopt: Correct treatment of loops: pre function in walker
+ breaks all possible loops in Phi and Block nodes.
+ irr_loop_example: wrong Return statement
+ Now I fixed all but one error: in memory_example.
+ This error showed a conceptual problem, so I wrote
+ a slightly different algorithm. This now runs for
+ all testprograms.
+ dead_node_example: cse is buggy!! merges start and the
+ following block!
+
+ 15.8.2000 Goetz
+ looking at bug in dead_node_elimination.
+ Following fixes:
+ irnode: all get_..._arr functions changed
+ ircons: new_r_Block: set matured flag.
+ ircons: new_r_SymConst: needs mode_p for linkage_ptr_info.
+ adapted call_str_example to new concepts.
+
+ 2.8.2000 Goetz
+ Implemented simpler Phi construction algorithm that constructs
+ correct code for three_cfpred_example in ircons. This algorithm
+ generates more Id nodes than the original algorithm and therefore
+ is less effective.
+ Also made some changes to optimizations of Not.
+
+ 31.7.2000 Chris
+ Fixed a bug, caused by the recursive use in type.h and entity.h.
+ Deleted the _TYPE_TYPEDEF_ and inserted the _ENTITY_TYPEDEF_ instead.
+ Fixed a problem in if_while testprogram, so it now works.
+
+ 20.7.2000 Goetz
+ Fixed bug in optimize(). Returned Null instead n if
+ get_optimize() == false.
+
+ 19.7.2000 Christian
+ Added some access routines in type.[hc]. Solved a recursive definition
+ of type_class struct, entity struct and type union.
+
+ 18.7.2000 Goetz
+ Separated entity header into pure functional header and header
+ with data types.
+
+ Goetz
+ ... a bunch small changes not documented
+
+ 12.7.2000 Goetz
+ Changed output of oo_prog_example: now uses the internal list
+ of all irgs. Had to implement some of the access routines for
+ that. Also fixed a bug in irdump. Main routines did not use
+ current_ir_graph properly.
+
+ 12.7.2000 Goetz
+ Implemented some missing parts in irgopt.
+ Added field irg to entity. Only valid if entity is a method.
+ Had to resove a cyclic de[endency between irgraph.h and entity.h
+ for this.
+ Added fields sub and super to type_class for inheritance.
+ Added field main_irg to irprog.
+
+ 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:
projects / libfirm / blobdiff
