3 [NOTE: This change is only forward binary compatible !
5 This means that this version of the symbol writer can still read
6 symbol files from the last mono release, but an older version of
7 the symbol writer can't read the new symbol files.
9 * MonoSymbolFile.cs (MonoSymbolFile): Removed 'FindMethod' and
12 * MonoSymbolTable.cs (MethodEntry): Don't write the method's full
13 name into the symbol file.
14 [NOTE: For the moment, the corresponding fields are still being
15 written into the symbol file. They'll be removed shortly before
16 the next mono release.]
18 2004-01-16 Martin Baulig <martin@ximian.com>
20 * MonoSymbolFile.cs (MonoDebuggerSupport): As suggested by Ben
21 Maurer, create a delegate type for each of the methods and then
24 2004-01-15 Martin Baulig <martin@ximian.com>
26 * MonoSymbolFile.cs (MonoDebuggerSupport): New public class
27 containing static wrappers for calling the `MonoDebugger_*'
28 function in S.R.Assembly.
30 2004-01-13 Martin Baulig <martin@ximian.com>
32 * MonoSymbolTable.cs: Added more #region's and a comment at the
35 * MonoSymbolWriter.cs (SourceMethod.BuildLineNumberTable): Removed
36 it here since it's in MethodEntry again.
38 2004-01-13 Martin Baulig <martin@ximian.com>
40 * ChangeLog, MonoSymbolTable.cs: Reviewed Ben's patches. For
41 those which are not ok, I'll add detailed comments to the source
44 2003-12-28 Ben Maurer <bmaurer@users.sourceforge.net>
46 [Revision 1.41, not approved. Martin]
47 * MonoSymbolTable.cs (MethodEntry): kill more
50 2003-12-28 Ben Maurer <bmaurer@users.sourceforge.net>
52 [Revision 1.40, not approved. Martin]
53 * MonoSymbolTable.cs (MethodEntry): Remove the
54 SourceFileIndex field, we already have the info.
56 2003-12-28 Ben Maurer <bmaurer@users.sourceforge.net>
58 [Revision 1.39, approved. Martin]
59 * MonoSymbolTable.cs: Don't make the MethodIndexEntry
60 part of the method entry class, because it just
63 2003-12-28 Ben Maurer <bmaurer@users.sourceforge.net>
65 [Revisions 1.37 and 1.38; not approved. Martin]
66 * MonoSymbolTable.cs (MethodEntry.BuildLineNumberTable): Removed.
68 * MonoSymbolTable.cs, MonoSymbolWriter.cs: Use
69 fewer arrays, dont use arraylists with structs.
71 2003-12-27 Ben Maurer <bmaurer@users.sourceforge.net>
73 * MonoSymbolFile.cs: Much, much better string writing.
75 2003-12-20 Ben Maurer <bmaurer@users.sourceforge.net>
77 [Revision 1.36, approved. Martin]
78 * MonoSymbolTable.cs: Fewer StringBuilder allocs.
80 2003-12-08 Zoltan Varga <vargaz@freemail.hu>
82 * MonoSymbolWriter.cs: Create ArrayLists only when needed.
84 2003-12-07 Ben Maurer <bmaurer@users.sourceforge.net>
86 [Revision 1.35, approved. Martin]
87 * MonoSymbolTable.cs: It is faster to do a linear search
88 than it is to make a hashtable. Even though the linear
89 search is O(n^2) while the hashtable is O(n), the allocation
90 cost for a hashtable is *very* high, especially when only
91 a few members will be added.
93 2003-09-06 Martin Baulig <martin@ximian.com>
95 * MonoSymbolFile.cs: Removed debugging output.
97 2003-08-05 Martin Baulig <martin@ximian.com>

113 field. Specifies whether two local variables have the same name.
115 2003-03-13 Martin Baulig <martin@ximian.com>
117 Added basic support for lexical scopes. This is just to tell a
118 debugger that a local variable is only available in a specific
119 lexical scope and that another variable of the same name may exist
120 in another lexical scope. See debugger/test/TestLexicalScope.cs
123 * MonoSymbolTable.cs (LexicalScopeEntry): New class.
124 (LocalVariableEntry): Added `BlockIndex' field which specifies the
125 lexical scope of this variable.
127 * MonoSymbolWriter.cs (SourceBlock): Removed, we're now using
128 LexicalScopeEntry instead.
130 2003-02-22 Martin Baulig <martin@ximian.com>

155 (MethodEntry.LocalTypes): New public variable.
157 2003-02-18 Martin Baulig <martin@ximian.com>
159 * MonoSymbolFile.cs (MethodEntry.ThisTypeIndex): Renamed to
160 ClassTypeIndex; provide this for all methods so we can get the
161 class of static methods.
163 2003-02-10 Nick Drochak <ndrochak@gol.com>
165 * Mono.CSharp.Debugger.build: passing the /r using an 'arg' node works.
166 The <include> node wasn't getting to the compiler. This fixes build

172 2003-02-09 Martin Baulig <martin@ximian.com>
174 * MonoSymbolWriter.cs (MonoSymbolWriter.ctor): We don't need the
175 `mbuilder_array' anymore.
177 2003-02-09 Martin Baulig <martin@ximian.com>
179 * MonoSymbolWriter.cs (SourceFile): Derive from SourceFileEntry.
180 (SourceBlock): We don't need source lines here.

183 * MonoSymbolTable.cs: Added support for namespaces.
184 (NamespaceEntry): New struct.
185 (SourceFileEntry.DefineNamespace): New method.
186 (MethodEntry.BuildLineNumberTable): The table is already sorted,
187 so we don't need to do this here.
189 2003-02-09 Martin Baulig <martin@ximian.com>
191 * IMonoSymbolWriter.cs: Ooops, I forgot to remove this.
193 2003-02-08 Martin Baulig <martin@ximian.com>
195 * MonoSymbolDocumentWriter.cs: Removed.
197 * MonoSymbolWriter.cs (SourceFile): Implement ISymbolDocumentWriter.

211 static method, returns null (without throwing an exception) if the
212 assembly doesn't have any debugging info.
214 2003-02-07 Martin Baulig <martin@ximian.com>
216 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Removed the
217 custom initialization function.
219 * MonoSymbolTableWriter.cs: Removed; the code is now in
220 MonoSymbolFile.cs and MonoSymbolWriter.cs.
222 2003-02-07 Martin Baulig <martin@ximian.com>
224 * MonoSymbolFile.cs: The symbol file is now a resource in the
225 assembly instead of a separate file.
227 * MonoSymbolTable.cs: Did a few more cleanups, sort the line
228 number table and remove duplicate line numbers.
230 2003-02-05 Martin Baulig <martin@ximian.com>
232 Modified the symbol file format to speed up method looks by name
233 and cleaned this up a lot.
235 * MonoSymbolFile.cs: New public class. This is now a public class
236 and writes and reads the symbol file.
238 * IMonoBinaryReader.cs: Removed.
240 * MonoSymbolTable.cs: Set version number to 29.
242 2003-01-17 Zoltan Varga <vargaz@freemail.hu>

252 2002-10-13 Martin Baulig <martin@gnome.org>
254 * MonoSymbolTable.cs: Set version number to 27. Added a source
255 file table which is used to search a method by source file + line number.
257 2002-09-21 Martin Baulig <martin@gnome.org>
259 * MonoSymbolTable.cs: Set version number to 26. Removed all the dynamic
260 stuff, this library now just deals with the compiler generated symbol table.
261 The dynamic stuff is private between the JIT and the debugger.
263 2002-09-21 Martin Baulig <martin@gnome.org>
265 * MonoSymbolTable.cs: Set version number to 25. Added information about
268 2002-09-20 Martin Baulig <martin@gnome.org>
270 * MonoSymbolTable.cs: Set version number to 24. Added a type index
271 table. Write the type of a local variable or a parameter as an index
274 2002-09-20 Martin Baulig <martin@gnome.org>
276 * IMonoSymbolWriter.cs: Remove all the unused interfaces.
278 2002-09-20 Martin Baulig <martin@gnome.org>

286 about parameters and local variables.
288 2002-09-20 Martin Baulig <martin@gnome.org>
290 * IMonoSymbolWriter.cs: Use fullly qualified name for
291 System.Diagnostics.SymbolStore.ISymbolWriter rather than `using' this
292 namespace. This allows us to use the name `ISymbolWriter' in our own
295 2002-09-18 Martin Baulig <martin@gnome.org>
297 * MonoSymbolTable.cs: Set version number to 21. Encode the source file
298 as a 4-byte length field followed by the UTF8 encoded string.

310 2002-09-14 Martin Baulig <martin@gnome.org>
312 * MonoSymbolWriter.cs, IMonoSymbolWriter.cs, MonoSymbolTableWriter.cs:
313 Make all classes and interfaces which don't need to be public internal.
315 2002-09-14 Martin Baulig <martin@gnome.org>
317 * MonoSymbolTable.cs: Use only CLS-compliant types here, bumped version
320 * MonoSymbolTableReader.cs: Removed, this is now in the debugger.
322 2002-09-03 Martin Baulig <martin@gnome.org>
324 * AssemblerWriterI386.cs, IAssemblerWriter.cs, MonoDwarfFileWriter.cs,
325 README, README.relocation-table, csharp-lang.[ch], gdb-csharp-support.patch,
326 gdb-variable-scopes.patch: Removed.
328 2002-09-03 Martin Baulig <martin@gnome.org>
330 * MonoSymbolTableReader.cs (MonoSymbolTableReader.ImageFile): New
333 * MonoSymbolTable.cs: Bumped version number to 18.
335 2002-08-27 Martin Baulig <martin@gnome.org>

341 * MonoSymbolTable.cs: Changed the file format in a way that allows us
342 open it read-only and to use a specially malloced area for all the
345 2002-08-25 Martin Baulig <martin@gnome.org>
347 * MonoSymbolTableReader.cs: New file. This is the reader for the
348 new symbol file format.
350 2002-08-24 Martin Baulig <martin@gnome.org>
352 * MonoSymbolTable.cs, MonoSymbolTableWriter.cs: New files. This
353 creates a binary application.dbg file which will be used by the
354 JIT to display source lines for exceptions.
356 * list.unix: Disabled the dwarf file writer in the build.
358 2002-08-23 Martin Baulig <martin@gnome.org>
360 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Added
361 assembly name argument. Since the symbol writer needs to read the
362 final assembly, we need to give it its full pathname.
364 2002-08-23 Martin Baulig <martin@gnome.org>
366 * makefile.gnu, list.unix: Added.
368 2002-07-05 Martin Baulig <martin@gnome.org>
370 * MonoDwarfFileWriter.cs: Added support for types in referenced assemblies.
372 2002-07-05 Martin Baulig <martin@gnome.org>
374 * MonoDwarfFileWriter.cs: Added support for arrays.
376 * gdb-csharp-support.patch: Updated.
378 2002-06-29 Martin Baulig <martin@gnome.org>
380 * MonoDwarfFileWriter.cs (DieInheritance): Make this actually work.
382 2002-06-29 Martin Baulig <martin@gnome.org>
384 * MonoDwarfFileWriter.cs, MonoSymbolWriter.cs: Put all TAG_subprogram's into their
385 corresponding struct/class declarations.
387 2002-06-28 Martin Baulig <martin@gnome.org>
389 * gdb-csharp-support.patch: Updated.
391 2002-06-28 Martin Baulig <martin@gnome.org>
393 * MonoDwarfFileWriter.cs: Use a TAG_string_type when we're using GNU extensions.
394 Make static struct/class fields actually work. Provide a TAG_typedef for struct's
397 2002-05-30 Martin Baulig <martin@gnome.org>
399 * IMonoSymbolWriter (IMonoSymbolWriter): Added custom `Initialize' method.
401 * MonoSymbolWriter.cs (Initialize): The ISymbolWriter's `Initialize' method
402 is no longer supported and throws an exception.
403 (Initialize (string, string[])): New custom initialization function.
405 * MonoDwarfFileWriter.cs (DwarfFileWriter): Added `string[] args' argument
406 to the constructor to pass command line arguments.
408 * gdb-csharp-support.patch: Updated for GDB 5.2.
410 2002-05-30 Martin Baulig <martin@gnome.org>
412 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now get's the
413 AssemblyBuilder's `methods' array as third argument.
414 (OpenMethod): Use this array to get the method builder rather than using an
416 (get_method_builder): Removed this interncall.
418 2002-05-25 Martin Baulig <martin@gnome.org>
420 * MonoDwarfFileWriter.cs: Finished the type rewrite, put back strings and arrays.
422 2002-05-24 Martin Baulig <martin@gnome.org>
424 * IMonoSymbolWriter.cs (ISourceMethod): Added `FullName' and `Parameters'.
425 (ITypeHandle): New interface.
427 * DwarfFileWriter.cs: Largely reorganized the type writing code. Types are
428 now represented by ITypeHandle objects which are stored in a per-dwarf-writer
429 hash table. At the moment, all types still need to be in one compile unit due
430 to lacking support in gdb - but this new type code here already supports this.
432 * MonoSymbolWriter.cs: Moved all the subclasses to the top-level and made them
433 public, cleaned up the code, put everything into one compile unit.
434 (DefineLocalVariable): Added a version of this function which takes useful args.
436 2002-05-22 Martin Baulig <martin@gnome.org>
438 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Added `Sources' and `Methods'
441 * MonoDwarfFileWriter.cs (WriteSymbolTable): New public method. Moved the
442 code that writes the "mono_line_numbers" section here from the LineNumberEngine.
444 2002-05-22 Martin Baulig <martin@gnome.org>
446 * IMonoSymbolWriter.cs (IVariable): Replaced Token with `ISourceMethod Method'.
448 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now has an additional
449 ModuleBuilder argument.
450 (OpenMethod): Immediately call the `get_method' interncall to get the MethodBase
451 from the token, then store the MethodBase instead of the token. The token may
452 still change during the metadata library's fixup process.
453 (DoFixups): When the image has been written to disk, call the GetToken () method
454 on all MethodBuilders and all ConstructorBuilders to get the final metadata tokens.
456 2002-05-22 Martin Baulig <martin@gnome.org>
458 * AssemblerWriterI386.cs: Don't use GNU extensions and produce assembler
459 output which is free of comments and extra whitespaces so that it's suitable
462 2002-05-22 Martin Baulig <martin@gnome.org>
464 * IMonoSymbolWriter.cs (ISourceMethod): Replaced `MethodInfo MethodInfo' with
465 `MethodBase MethodBase' and added `Type ReturnType'. We're now correctly
466 dealing with constructors and not crashing anymore.
468 2002-05-21 Martin Baulig <martin@gnome.org>
470 * MonoDwarfFileWriter.cs: Write a special line number table which can be read
471 in by the metadata library to get line number information in backtraces.
473 2002-05-06 Martin Baulig <martin@gnome.org>
475 * MonoSymbolWriter.cs (MonoSymbolWriter.Close): Use Assembly.LoadFrom (), not
476 AppDomain.Load () to load the assembly.
478 2002-04-26 Martin Baulig <martin@gnome.org>
480 * gdb-csharp-support.patch: A patch for GDB (against the latest CVS version)
481 to implement C# support.
483 * csharp-lang.c, csharp-lang.h, csharp-mono-lang.c: Copy these into your GDB
484 source directory after applying the patch.
486 2002-04-26 Martin Baulig <martin@gnome.org>
488 * MonoDwarfFileWriter.cs (DieInternalString): Removed.
490 2002-04-25 Martin Baulig <martin@gnome.org>
492 * MonoDwarfFileWriter.cs: Reflect latest MonoString changes.
494 2002-04-13 Martin Baulig <martin@gnome.org>
496 * IMonoSymbolWriter.cs (ISourceBlock): Added `Blocks' property and `AddBlock'
497 method to support nested blocks.
499 * MonoSymbolWriter.cs: Correctly handle nested blocks.
501 * MonoDwarfFileWriter.cs (DieMember): Provide info for all fields, not just for
502 public ones; also added DW_AT_accessibility.
503 (DieVariable): Reflected latest debug-symfile.c changes.
505 2002-04-12 Martin Baulig <martin@gnome.org>
507 * gdb-variable-scopes.patch: A patch for GDB (against the latest CVS version)
508 to implement variable lifetimes.
510 2002-04-12 Martin Baulig <martin@gnome.org>
512 * MonoDwarfFileWriter.cs (DieVariable): Provide info about the variable's
513 lifetime using DW_AT_begin_scope and a new baulig extension DW_AT_end_scope.
515 2002-03-29 Martin Baulig <martin@gnome.org>
517 * AssemblerWriterI386.cs: Rewrote most of the string output function, do the
518 number->string conversion manually. It's now taking about 15 seconds to write
519 a symbol file for MCS, no longer more than a minute.
521 * MonoDwarfFileWriter.cs: Added some profiling code, speeded things up, fixed
524 2002-03-25 Martin Baulig <martin@gnome.org>
526 * MonoDwarfFileWriter.cs (CreateType): Return a `DieType'.
527 (RegisterType): Add the type to the type hash before creating dependency types
528 so we don't get recursion loops.
529 (RegisterPointerType): New func to register a "pointer to type" type.
530 (DieTypeDef, DiePointerType, DieArrayType, DieStringType, DieClassType): New
531 types; added support for strings, arrays and basic support for classes.
533 2002-03-24 Martin Baulig <martin@gnome.org>
535 * IMonoSymbolWriter.cs: Killed all methods in this interface, no longer needed.
537 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now takes a string
538 argument which is the full pathname of the assembly - you must call Close()
539 after the assembly has been written to disk since the symbol writer needs to
540 load the finished assembly to get its metadata.
542 * MonoDwarfFileWriter.cs: Added support for enums and structs.
544 2002-03-24 Martin Baulig <martin@gnome.org>
546 * MonoDwarfFileWriter.cs: Added support for method parameters.
548 2002-03-24 Martin Baulig <martin@gnome.org>
550 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Removed my custom OpenMethod(),
551 we're now using the ISymbolWriter's method.
552 (IVariable): Added `byte[] Signature' property.
554 * MonoSymbolWriter.cs (SetAssembly): New method. This must be called before
555 Close(); the assembly parameter is the already-written assembly, ie. it must
556 contain the full metadata.
557 (OpenMethod): Only take the token argument and set MethodInfo later in DoFixups.
558 (SetMethodSourceRange): You must call this function to tell the symbol writer
559 in which source file the method is defined.
560 (DefineLocal): Store the signature in the local.
561 (DoFixups): Use two new interncalls to set the SourceMethod's MethodInfo field
562 and the LocalVariable's Type field.
564 2002-03-23 Martin Baulig <martin@gnome.org>
566 * IMonoSymbolWriter.cs (ISourceBlock): New interface.
567 (ILocalVariable): Renamed this interface to IVariable.
568 (IVariable): Added Line, Type, Token.
569 (ILocalVariable, IMethodParameter): New interfaces, derive from IVariable.
570 (ISourceMethod): Added Blocks. Renamed FirstLine and LastLine to Start and End,
571 changed their type to ISourceLine. Removed CodeSize.
572 (ISourceLine): Renamed Line to Row, added Column. Added OffsetType and Offset.
574 * MonoDwarfFileWriter.cs (MonoDwarfFileWriter.DieLexicalBlock): New class.
575 (MonoDwarfFileWriter.DieMethodVariable): New class.
577 * MonoSymbolWriter.cs (OpenScope, CloseScope): Implemented.
578 Reflected latest IMonoSymbolWriter interface changes.
580 2002-03-20 Martin Baulig <martin@gnome.org>
582 * IAssemblerWriter.cs: New interface.
584 * AssemblerWriterI386.cs: New class.
586 * MonoDwarfFileWriter.cs: Use the IAssemblerWriter interface to make this class
587 platform and assembler independent.
589 2002-03-20 Martin Baulig <martin@gnome.org>
591 * IMonoSymbolWriter.cs (ISourceMethod): Added FirstLine, LastLine, CodeSize and
594 * MonoDwarfFileWriter.cs: Implemented line number support.
596 2002-03-19 Martin Baulig <martin@gnome.org>
598 * IMonoSymbolWriter.cs (ISourceFile, ISourceMethod, ISourceLine, ILocalVariable):
601 * IMonoSymbolWriter.cs (OpenMethod): Take a System.Reflection.MethodInfo, not
604 2002-03-19 Martin Baulig <martin@gnome.org>
606 This is an implementation of the System.Diagnostics.SymbolStore.SymbolWriter
607 interface. It's still work in progress and not yet used anywhere.
609 There is some preliminary documentation in the source files and some more
610 docu in the README and README.relocation-table files.
612 * IMonoSymbolWriter.cs: New file.
613 * MonoDwarfFileWriter.cs: New file.
614 * MonoSymbolDocumentWriter.cs: New file.
