1 2003-12-27 Ben Maurer <bmaurer@users.sourceforge.net>
3 * MonoSymbolFile.cs: Much, much better string writing.
5 2003-12-20 Ben Maurer <bmaurer@users.sourceforge.net>
7 * MonoSymbolTable.cs: Fewer StringBuilder allocs.
9 2003-12-08 Zoltan Varga <vargaz@freemail.hu>
11 * MonoSymbolWriter.cs: Create ArrayLists only when needed.
13 2003-12-07 Ben Maurer <bmaurer@users.sourceforge.net>
15 * MonoSymbolTable.cs: It is faster to do a linear search
16 than it is to make a hashtable. Even though the linear
17 search is O(n^2) while the hashtable is O(n), the allocation
18 cost for a hashtable is *very* high, especially when only
19 a few members will be added.
21 2003-09-06 Martin Baulig <martin@ximian.com>
23 * MonoSymbolFile.cs: Removed debugging output.
25 2003-08-05 Martin Baulig <martin@ximian.com>

41 field. Specifies whether two local variables have the same name.
43 2003-03-13 Martin Baulig <martin@ximian.com>
45 Added basic support for lexical scopes. This is just to tell a
46 debugger that a local variable is only available in a specific
47 lexical scope and that another variable of the same name may exist
48 in another lexical scope. See debugger/test/TestLexicalScope.cs
51 * MonoSymbolTable.cs (LexicalScopeEntry): New class.
52 (LocalVariableEntry): Added `BlockIndex' field which specifies the
53 lexical scope of this variable.
55 * MonoSymbolWriter.cs (SourceBlock): Removed, we're now using
56 LexicalScopeEntry instead.
58 2003-02-22 Martin Baulig <martin@ximian.com>

83 (MethodEntry.LocalTypes): New public variable.
85 2003-02-18 Martin Baulig <martin@ximian.com>
87 * MonoSymbolFile.cs (MethodEntry.ThisTypeIndex): Renamed to
88 ClassTypeIndex; provide this for all methods so we can get the
89 class of static methods.
91 2003-02-10 Nick Drochak <ndrochak@gol.com>
93 * Mono.CSharp.Debugger.build: passing the /r using an 'arg' node works.
94 The <include> node wasn't getting to the compiler. This fixes build
97 * MonoSymbolFile.cs: Qualify which Min method. Fixes build breakage
100 2003-02-09 Martin Baulig <martin@ximian.com>
102 * MonoSymbolWriter.cs (MonoSymbolWriter.ctor): We don't need the
103 `mbuilder_array' anymore.
105 2003-02-09 Martin Baulig <martin@ximian.com>
107 * MonoSymbolWriter.cs (SourceFile): Derive from SourceFileEntry.
108 (SourceBlock): We don't need source lines here.
109 (SourceMethod): We're always constructed with source info.
111 * MonoSymbolTable.cs: Added support for namespaces.
112 (NamespaceEntry): New struct.
113 (SourceFileEntry.DefineNamespace): New method.
114 (MethodEntry.BuildLineNumberTable): The table is already sorted,
115 so we don't need to do this here.
117 2003-02-09 Martin Baulig <martin@ximian.com>
119 * IMonoSymbolWriter.cs: Ooops, I forgot to remove this.
121 2003-02-08 Martin Baulig <martin@ximian.com>
123 * MonoSymbolDocumentWriter.cs: Removed.
125 * MonoSymbolWriter.cs (SourceFile): Implement ISymbolDocumentWriter.

136 2003-02-07 Martin Baulig <martin@ximian.com>
138 * MonoSymbolFile.cs (MonoSymbolFile.ReadSymbolFile): New public
139 static method, returns null (without throwing an exception) if the
140 assembly doesn't have any debugging info.
142 2003-02-07 Martin Baulig <martin@ximian.com>
144 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Removed the
145 custom initialization function.
147 * MonoSymbolTableWriter.cs: Removed; the code is now in
148 MonoSymbolFile.cs and MonoSymbolWriter.cs.
150 2003-02-07 Martin Baulig <martin@ximian.com>
152 * MonoSymbolFile.cs: The symbol file is now a resource in the
153 assembly instead of a separate file.
155 * MonoSymbolTable.cs: Did a few more cleanups, sort the line
156 number table and remove duplicate line numbers.
158 2003-02-05 Martin Baulig <martin@ximian.com>
160 Modified the symbol file format to speed up method looks by name
161 and cleaned this up a lot.
163 * MonoSymbolFile.cs: New public class. This is now a public class
164 and writes and reads the symbol file.
166 * IMonoBinaryReader.cs: Removed.
168 * MonoSymbolTable.cs: Set version number to 29.
170 2003-01-17 Zoltan Varga <vargaz@freemail.hu>
172 * MonoSymbolWriter.cs (OpenMethod): Make it work on constructors.
174 2002-10-13 Martin Baulig <martin@gnome.org>
176 * MonoSymbolTable.cs: Set version number to 28.
177 (SourceFileEntry): Read the methods when they're needed.
178 (MethodSourceEntry): Made this a struct, not a class.
180 2002-10-13 Martin Baulig <martin@gnome.org>
182 * MonoSymbolTable.cs: Set version number to 27. Added a source
183 file table which is used to search a method by source file + line number.
185 2002-09-21 Martin Baulig <martin@gnome.org>
187 * MonoSymbolTable.cs: Set version number to 26. Removed all the dynamic
188 stuff, this library now just deals with the compiler generated symbol table.
189 The dynamic stuff is private between the JIT and the debugger.
191 2002-09-21 Martin Baulig <martin@gnome.org>
193 * MonoSymbolTable.cs: Set version number to 25. Added information about
196 2002-09-20 Martin Baulig <martin@gnome.org>
198 * MonoSymbolTable.cs: Set version number to 24. Added a type index
199 table. Write the type of a local variable or a parameter as an index
202 2002-09-20 Martin Baulig <martin@gnome.org>
204 * IMonoSymbolWriter.cs: Remove all the unused interfaces.
206 2002-09-20 Martin Baulig <martin@gnome.org>
208 * MonoSymbolTable.cs: Set version number to 23, include the size
211 2002-09-20 Martin Baulig <martin@gnome.org>
213 * MonoSymbolTable.cs: Set version number to 22. Provide information
214 about parameters and local variables.
216 2002-09-20 Martin Baulig <martin@gnome.org>
218 * IMonoSymbolWriter.cs: Use fullly qualified name for
219 System.Diagnostics.SymbolStore.ISymbolWriter rather than `using' this
220 namespace. This allows us to use the name `ISymbolWriter' in our own
223 2002-09-18 Martin Baulig <martin@gnome.org>
225 * MonoSymbolTable.cs: Set version number to 21. Encode the source file
226 as a 4-byte length field followed by the UTF8 encoded string.
228 2002-09-18 Martin Baulig <martin@gnome.org>
230 * IMonoBinaryReader.cs: New interface.

238 2002-09-14 Martin Baulig <martin@gnome.org>
240 * MonoSymbolWriter.cs, IMonoSymbolWriter.cs, MonoSymbolTableWriter.cs:
241 Make all classes and interfaces which don't need to be public internal.
243 2002-09-14 Martin Baulig <martin@gnome.org>
245 * MonoSymbolTable.cs: Use only CLS-compliant types here, bumped version
248 * MonoSymbolTableReader.cs: Removed, this is now in the debugger.
250 2002-09-03 Martin Baulig <martin@gnome.org>
252 * AssemblerWriterI386.cs, IAssemblerWriter.cs, MonoDwarfFileWriter.cs,
253 README, README.relocation-table, csharp-lang.[ch], gdb-csharp-support.patch,
254 gdb-variable-scopes.patch: Removed.
256 2002-09-03 Martin Baulig <martin@gnome.org>
258 * MonoSymbolTableReader.cs (MonoSymbolTableReader.ImageFile): New
261 * MonoSymbolTable.cs: Bumped version number to 18.
263 2002-08-27 Martin Baulig <martin@gnome.org>

270 open it read-only and to use a specially malloced area for all the
273 2002-08-25 Martin Baulig <martin@gnome.org>
275 * MonoSymbolTableReader.cs: New file. This is the reader for the
276 new symbol file format.
278 2002-08-24 Martin Baulig <martin@gnome.org>
280 * MonoSymbolTable.cs, MonoSymbolTableWriter.cs: New files. This
281 creates a binary application.dbg file which will be used by the
282 JIT to display source lines for exceptions.
284 * list.unix: Disabled the dwarf file writer in the build.
286 2002-08-23 Martin Baulig <martin@gnome.org>
288 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Added
289 assembly name argument. Since the symbol writer needs to read the
290 final assembly, we need to give it its full pathname.
292 2002-08-23 Martin Baulig <martin@gnome.org>
294 * makefile.gnu, list.unix: Added.
296 2002-07-05 Martin Baulig <martin@gnome.org>
298 * MonoDwarfFileWriter.cs: Added support for types in referenced assemblies.
300 2002-07-05 Martin Baulig <martin@gnome.org>
302 * MonoDwarfFileWriter.cs: Added support for arrays.
304 * gdb-csharp-support.patch: Updated.
306 2002-06-29 Martin Baulig <martin@gnome.org>
308 * MonoDwarfFileWriter.cs (DieInheritance): Make this actually work.
310 2002-06-29 Martin Baulig <martin@gnome.org>
312 * MonoDwarfFileWriter.cs, MonoSymbolWriter.cs: Put all TAG_subprogram's into their
313 corresponding struct/class declarations.
315 2002-06-28 Martin Baulig <martin@gnome.org>
317 * gdb-csharp-support.patch: Updated.
319 2002-06-28 Martin Baulig <martin@gnome.org>
321 * MonoDwarfFileWriter.cs: Use a TAG_string_type when we're using GNU extensions.
322 Make static struct/class fields actually work. Provide a TAG_typedef for struct's
325 2002-05-30 Martin Baulig <martin@gnome.org>
327 * IMonoSymbolWriter (IMonoSymbolWriter): Added custom `Initialize' method.
329 * MonoSymbolWriter.cs (Initialize): The ISymbolWriter's `Initialize' method
330 is no longer supported and throws an exception.
331 (Initialize (string, string[])): New custom initialization function.
333 * MonoDwarfFileWriter.cs (DwarfFileWriter): Added `string[] args' argument
334 to the constructor to pass command line arguments.
336 * gdb-csharp-support.patch: Updated for GDB 5.2.
338 2002-05-30 Martin Baulig <martin@gnome.org>
340 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now get's the
341 AssemblyBuilder's `methods' array as third argument.
342 (OpenMethod): Use this array to get the method builder rather than using an
344 (get_method_builder): Removed this interncall.
346 2002-05-25 Martin Baulig <martin@gnome.org>
348 * MonoDwarfFileWriter.cs: Finished the type rewrite, put back strings and arrays.
350 2002-05-24 Martin Baulig <martin@gnome.org>
352 * IMonoSymbolWriter.cs (ISourceMethod): Added `FullName' and `Parameters'.
353 (ITypeHandle): New interface.
355 * DwarfFileWriter.cs: Largely reorganized the type writing code. Types are
356 now represented by ITypeHandle objects which are stored in a per-dwarf-writer
357 hash table. At the moment, all types still need to be in one compile unit due
358 to lacking support in gdb - but this new type code here already supports this.
360 * MonoSymbolWriter.cs: Moved all the subclasses to the top-level and made them
361 public, cleaned up the code, put everything into one compile unit.
362 (DefineLocalVariable): Added a version of this function which takes useful args.
364 2002-05-22 Martin Baulig <martin@gnome.org>
366 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Added `Sources' and `Methods'
369 * MonoDwarfFileWriter.cs (WriteSymbolTable): New public method. Moved the
370 code that writes the "mono_line_numbers" section here from the LineNumberEngine.
372 2002-05-22 Martin Baulig <martin@gnome.org>
374 * IMonoSymbolWriter.cs (IVariable): Replaced Token with `ISourceMethod Method'.
376 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now has an additional
377 ModuleBuilder argument.
378 (OpenMethod): Immediately call the `get_method' interncall to get the MethodBase
379 from the token, then store the MethodBase instead of the token. The token may
380 still change during the metadata library's fixup process.
381 (DoFixups): When the image has been written to disk, call the GetToken () method
382 on all MethodBuilders and all ConstructorBuilders to get the final metadata tokens.
384 2002-05-22 Martin Baulig <martin@gnome.org>
386 * AssemblerWriterI386.cs: Don't use GNU extensions and produce assembler
387 output which is free of comments and extra whitespaces so that it's suitable
390 2002-05-22 Martin Baulig <martin@gnome.org>
392 * IMonoSymbolWriter.cs (ISourceMethod): Replaced `MethodInfo MethodInfo' with
393 `MethodBase MethodBase' and added `Type ReturnType'. We're now correctly
394 dealing with constructors and not crashing anymore.
396 2002-05-21 Martin Baulig <martin@gnome.org>
398 * MonoDwarfFileWriter.cs: Write a special line number table which can be read
399 in by the metadata library to get line number information in backtraces.
401 2002-05-06 Martin Baulig <martin@gnome.org>
403 * MonoSymbolWriter.cs (MonoSymbolWriter.Close): Use Assembly.LoadFrom (), not
404 AppDomain.Load () to load the assembly.
406 2002-04-26 Martin Baulig <martin@gnome.org>
408 * gdb-csharp-support.patch: A patch for GDB (against the latest CVS version)
409 to implement C# support.
411 * csharp-lang.c, csharp-lang.h, csharp-mono-lang.c: Copy these into your GDB
412 source directory after applying the patch.
414 2002-04-26 Martin Baulig <martin@gnome.org>
416 * MonoDwarfFileWriter.cs (DieInternalString): Removed.
418 2002-04-25 Martin Baulig <martin@gnome.org>
420 * MonoDwarfFileWriter.cs: Reflect latest MonoString changes.
422 2002-04-13 Martin Baulig <martin@gnome.org>
424 * IMonoSymbolWriter.cs (ISourceBlock): Added `Blocks' property and `AddBlock'
425 method to support nested blocks.
427 * MonoSymbolWriter.cs: Correctly handle nested blocks.
429 * MonoDwarfFileWriter.cs (DieMember): Provide info for all fields, not just for
430 public ones; also added DW_AT_accessibility.
431 (DieVariable): Reflected latest debug-symfile.c changes.
433 2002-04-12 Martin Baulig <martin@gnome.org>
435 * gdb-variable-scopes.patch: A patch for GDB (against the latest CVS version)
436 to implement variable lifetimes.
438 2002-04-12 Martin Baulig <martin@gnome.org>
440 * MonoDwarfFileWriter.cs (DieVariable): Provide info about the variable's
441 lifetime using DW_AT_begin_scope and a new baulig extension DW_AT_end_scope.
443 2002-03-29 Martin Baulig <martin@gnome.org>
445 * AssemblerWriterI386.cs: Rewrote most of the string output function, do the
446 number->string conversion manually. It's now taking about 15 seconds to write
447 a symbol file for MCS, no longer more than a minute.
449 * MonoDwarfFileWriter.cs: Added some profiling code, speeded things up, fixed
452 2002-03-25 Martin Baulig <martin@gnome.org>
454 * MonoDwarfFileWriter.cs (CreateType): Return a `DieType'.
455 (RegisterType): Add the type to the type hash before creating dependency types
456 so we don't get recursion loops.
457 (RegisterPointerType): New func to register a "pointer to type" type.
458 (DieTypeDef, DiePointerType, DieArrayType, DieStringType, DieClassType): New
459 types; added support for strings, arrays and basic support for classes.
461 2002-03-24 Martin Baulig <martin@gnome.org>
463 * IMonoSymbolWriter.cs: Killed all methods in this interface, no longer needed.
465 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now takes a string
466 argument which is the full pathname of the assembly - you must call Close()
467 after the assembly has been written to disk since the symbol writer needs to
468 load the finished assembly to get its metadata.
470 * MonoDwarfFileWriter.cs: Added support for enums and structs.
472 2002-03-24 Martin Baulig <martin@gnome.org>
474 * MonoDwarfFileWriter.cs: Added support for method parameters.
476 2002-03-24 Martin Baulig <martin@gnome.org>
478 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Removed my custom OpenMethod(),
479 we're now using the ISymbolWriter's method.
480 (IVariable): Added `byte[] Signature' property.
482 * MonoSymbolWriter.cs (SetAssembly): New method. This must be called before
483 Close(); the assembly parameter is the already-written assembly, ie. it must
484 contain the full metadata.
485 (OpenMethod): Only take the token argument and set MethodInfo later in DoFixups.
486 (SetMethodSourceRange): You must call this function to tell the symbol writer
487 in which source file the method is defined.
488 (DefineLocal): Store the signature in the local.
489 (DoFixups): Use two new interncalls to set the SourceMethod's MethodInfo field
490 and the LocalVariable's Type field.
492 2002-03-23 Martin Baulig <martin@gnome.org>
494 * IMonoSymbolWriter.cs (ISourceBlock): New interface.
495 (ILocalVariable): Renamed this interface to IVariable.
496 (IVariable): Added Line, Type, Token.
497 (ILocalVariable, IMethodParameter): New interfaces, derive from IVariable.
498 (ISourceMethod): Added Blocks. Renamed FirstLine and LastLine to Start and End,
499 changed their type to ISourceLine. Removed CodeSize.
500 (ISourceLine): Renamed Line to Row, added Column. Added OffsetType and Offset.
502 * MonoDwarfFileWriter.cs (MonoDwarfFileWriter.DieLexicalBlock): New class.
503 (MonoDwarfFileWriter.DieMethodVariable): New class.
505 * MonoSymbolWriter.cs (OpenScope, CloseScope): Implemented.
506 Reflected latest IMonoSymbolWriter interface changes.
508 2002-03-20 Martin Baulig <martin@gnome.org>
510 * IAssemblerWriter.cs: New interface.
512 * AssemblerWriterI386.cs: New class.
514 * MonoDwarfFileWriter.cs: Use the IAssemblerWriter interface to make this class
515 platform and assembler independent.
517 2002-03-20 Martin Baulig <martin@gnome.org>
519 * IMonoSymbolWriter.cs (ISourceMethod): Added FirstLine, LastLine, CodeSize and
522 * MonoDwarfFileWriter.cs: Implemented line number support.
524 2002-03-19 Martin Baulig <martin@gnome.org>
526 * IMonoSymbolWriter.cs (ISourceFile, ISourceMethod, ISourceLine, ILocalVariable):
529 * IMonoSymbolWriter.cs (OpenMethod): Take a System.Reflection.MethodInfo, not
532 2002-03-19 Martin Baulig <martin@gnome.org>
534 This is an implementation of the System.Diagnostics.SymbolStore.SymbolWriter
535 interface. It's still work in progress and not yet used anywhere.
537 There is some preliminary documentation in the source files and some more
538 docu in the README and README.relocation-table files.
540 * IMonoSymbolWriter.cs: New file.
541 * MonoDwarfFileWriter.cs: New file.
542 * MonoSymbolDocumentWriter.cs: New file.
