+ 12.3.2001 Boris
+ added auto documentation in Makefiles, configure, etc
+ example in ir/ir/ircons.c - much must be added
+ creation of documentation by 'make autodoc' in architecture directory
+
+ 5.3.2001 Boris
+ added lots of #ifdef HAVE_CONFIG_G #include "config.h" #endif
+ replaced some C++ style comments (//) by standard C comments /**/
+ added autoconf stuff
+ worked this night:
+ - configure (with some features, see --help for more)
+ - make [depend | tags | install]
+ - make [run] in testprograms
+ did not work:
+ - compilation on SunOS
+ - make dist
+ - automatic call of autoconf if required
+
+ 5.3.2001 Goetz
+ More colours in vcg output.
+ Fixed bug: cse found that start block equals it's
+ first successor as both have the Start block as predecessor.
+ This only happens for local_optimize_graph() as during construction
+ the Start block is not entered in the value table.
+ Changed implementation: irgmod: local_optimize_graph() did not
+ empty the hash table with the irnodes for cse. This might cause that
+ cse turns up with a node that seems better but was removed from the
+ graph in an earlier optimization phase.
+ Removed old #if 1 from ircons.c
+ Commented in call of optimization for Block nodes in irgopt.c, copy_preds():
+ Optimizes blocks that had bad predecessors.
+ Same for Phi nodes.
+
+
+ 27.2.2001 Goetz
+ Moved struct from irprog.h to irprog_t.h, same for irmode.h.
+ Added a module deb_info in debug.h. Adapted makefile. Added example
+ use in iropt.h.
+ Removed use of debug.h in ident.c. Now debug.c|h can be moved to
+ /adt/.
+ Removed inabled code for dead node elimination in irgopt.h.
+ Renamed some missnamed access routines (_of_). Macros with old names
+ are in old_fctnames.h.
+ Edited makefiles to remove #* and *.flc.
+
+ ??.2.2001 Goetz
+ Some minor bugfixes...
+
+ 25.1.2001 Goetz
+ After compacting of in arrays in dead_node_elimination
+ merge blocks and remove Phis with one pred.
+
+ 24.1.2001 Goetz
+ Freeing of obstack in dead_node_elimination commented in.
+ Compacting in arrays of Block and Phi nodes in dead_node_
+ elimination.
+ Some more changes...
+
+ 15.01.2001 Goetz
+ added set/get_SymConst_type_or_id in irnode.h
+ added field offset to entity in entity.h
+ added field size to type_class in type.h
+ include "gmp.h" in tv.h with "" instead <>
+
+ 12.01.2001 Goetz
+ Some changes to make the lib better portable
+
+ 29.12.2000 Goetz
+ Initialize max_node_nr in irprog.
+
+ 27.12.2000 Goetz
+ Now outputs warning if faulty type in irdump, dump_type_info.
+ Explicit string termination in irdump, vcg_open.
+
+ 20.12.2000 Goetz
+ Added external to declaration of irp.
+ Added typedef before pns and pnc_number.
+ irmode.c, init_mode(): We need to memset all new modes as
+ tarval_vrfy reads fields before they are initialized: It
+ compares to min/max when tarvals for min/max are allocated!
+
+ 18.12.2000 Goetz
+ Changed parameter of Methods in type.h and type.c from
+ class to clss. Class is a C++ keyword.
+
+ 10.12.2000 Goetz
+ Changed some testprograms to accomodate Uebprakt.
+
+ 7.9.2000 Goetz
+ Finished implementation of dump_all_types.
+ Added new testprogram inheritance_example.
+
+ 6.9.2000 Chris
+ Added seven access routines in type.[hc]:
+ get_class_n_member, get_class_n_subtype, get_class_n_supertype,
+ get_strct_n_member, add_strct_member, get_strct_member and set_strct_member.
+ Fixed the type_walk_2 for those seven routines.
+
+ 6.9.2000 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 ==============================
+======================================================================
+
+ 3.9.2000 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.
Renamed dataseg to globals to be conformant with documentation.
- Added conservation of current_ir_graph to irgopt.c
+ Added conservation of current_ir_graph to irgopt.c.
+ Corrected bug in Makefiles: wrong path to directory ./inlude.
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
