3 * MonoSymbolTable.cs: It is faster to do a linear search
4 than it is to make a hashtable. Even though the linear
5 search is O(n^2) while the hashtable is O(n), the allocation
6 cost for a hashtable is *very* high, especially when only
7 a few members will be added.
9 2003-09-06 Martin Baulig <martin@ximian.com>
11 * MonoSymbolFile.cs: Removed debugging output.
13 2003-08-05 Martin Baulig <martin@ximian.com>

29 field. Specifies whether two local variables have the same name.
31 2003-03-13 Martin Baulig <martin@ximian.com>
33 Added basic support for lexical scopes. This is just to tell a
34 debugger that a local variable is only available in a specific
35 lexical scope and that another variable of the same name may exist
36 in another lexical scope. See debugger/test/TestLexicalScope.cs
39 * MonoSymbolTable.cs (LexicalScopeEntry): New class.
40 (LocalVariableEntry): Added `BlockIndex' field which specifies the
41 lexical scope of this variable.

73 2003-02-18 Martin Baulig <martin@ximian.com>
75 * MonoSymbolFile.cs (MethodEntry.ThisTypeIndex): Renamed to
76 ClassTypeIndex; provide this for all methods so we can get the
77 class of static methods.
79 2003-02-10 Nick Drochak <ndrochak@gol.com>
81 * Mono.CSharp.Debugger.build: passing the /r using an 'arg' node works.
82 The <include> node wasn't getting to the compiler. This fixes build

91 `mbuilder_array' anymore.
93 2003-02-09 Martin Baulig <martin@ximian.com>
95 * MonoSymbolWriter.cs (SourceFile): Derive from SourceFileEntry.
96 (SourceBlock): We don't need source lines here.

99 * MonoSymbolTable.cs: Added support for namespaces.
100 (NamespaceEntry): New struct.
101 (SourceFileEntry.DefineNamespace): New method.
102 (MethodEntry.BuildLineNumberTable): The table is already sorted,
103 so we don't need to do this here.
105 2003-02-09 Martin Baulig <martin@ximian.com>
107 * IMonoSymbolWriter.cs: Ooops, I forgot to remove this.
109 2003-02-08 Martin Baulig <martin@ximian.com>
111 * MonoSymbolDocumentWriter.cs: Removed.
113 * MonoSymbolWriter.cs (SourceFile): Implement ISymbolDocumentWriter.

127 static method, returns null (without throwing an exception) if the
128 assembly doesn't have any debugging info.
130 2003-02-07 Martin Baulig <martin@ximian.com>
132 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Removed the
133 custom initialization function.
135 * MonoSymbolTableWriter.cs: Removed; the code is now in
136 MonoSymbolFile.cs and MonoSymbolWriter.cs.
138 2003-02-07 Martin Baulig <martin@ximian.com>
140 * MonoSymbolFile.cs: The symbol file is now a resource in the
141 assembly instead of a separate file.
143 * MonoSymbolTable.cs: Did a few more cleanups, sort the line
144 number table and remove duplicate line numbers.
146 2003-02-05 Martin Baulig <martin@ximian.com>
148 Modified the symbol file format to speed up method looks by name
149 and cleaned this up a lot.
151 * MonoSymbolFile.cs: New public class. This is now a public class
152 and writes and reads the symbol file.
154 * IMonoBinaryReader.cs: Removed.
156 * MonoSymbolTable.cs: Set version number to 29.
158 2003-01-17 Zoltan Varga <vargaz@freemail.hu>

168 2002-10-13 Martin Baulig <martin@gnome.org>
170 * MonoSymbolTable.cs: Set version number to 27. Added a source
171 file table which is used to search a method by source file + line number.
173 2002-09-21 Martin Baulig <martin@gnome.org>
175 * MonoSymbolTable.cs: Set version number to 26. Removed all the dynamic
176 stuff, this library now just deals with the compiler generated symbol table.
177 The dynamic stuff is private between the JIT and the debugger.
179 2002-09-21 Martin Baulig <martin@gnome.org>
181 * MonoSymbolTable.cs: Set version number to 25. Added information about
184 2002-09-20 Martin Baulig <martin@gnome.org>
186 * MonoSymbolTable.cs: Set version number to 24. Added a type index
187 table. Write the type of a local variable or a parameter as an index
190 2002-09-20 Martin Baulig <martin@gnome.org>
192 * IMonoSymbolWriter.cs: Remove all the unused interfaces.
194 2002-09-20 Martin Baulig <martin@gnome.org>

202 about parameters and local variables.
204 2002-09-20 Martin Baulig <martin@gnome.org>
206 * IMonoSymbolWriter.cs: Use fullly qualified name for
207 System.Diagnostics.SymbolStore.ISymbolWriter rather than `using' this
208 namespace. This allows us to use the name `ISymbolWriter' in our own
211 2002-09-18 Martin Baulig <martin@gnome.org>
213 * MonoSymbolTable.cs: Set version number to 21. Encode the source file
214 as a 4-byte length field followed by the UTF8 encoded string.

226 2002-09-14 Martin Baulig <martin@gnome.org>
228 * MonoSymbolWriter.cs, IMonoSymbolWriter.cs, MonoSymbolTableWriter.cs:
229 Make all classes and interfaces which don't need to be public internal.
231 2002-09-14 Martin Baulig <martin@gnome.org>
233 * MonoSymbolTable.cs: Use only CLS-compliant types here, bumped version
236 * MonoSymbolTableReader.cs: Removed, this is now in the debugger.
238 2002-09-03 Martin Baulig <martin@gnome.org>
240 * AssemblerWriterI386.cs, IAssemblerWriter.cs, MonoDwarfFileWriter.cs,
241 README, README.relocation-table, csharp-lang.[ch], gdb-csharp-support.patch,
242 gdb-variable-scopes.patch: Removed.
244 2002-09-03 Martin Baulig <martin@gnome.org>
246 * MonoSymbolTableReader.cs (MonoSymbolTableReader.ImageFile): New
249 * MonoSymbolTable.cs: Bumped version number to 18.
251 2002-08-27 Martin Baulig <martin@gnome.org>

258 open it read-only and to use a specially malloced area for all the
261 2002-08-25 Martin Baulig <martin@gnome.org>
263 * MonoSymbolTableReader.cs: New file. This is the reader for the
264 new symbol file format.
266 2002-08-24 Martin Baulig <martin@gnome.org>
268 * MonoSymbolTable.cs, MonoSymbolTableWriter.cs: New files. This
269 creates a binary application.dbg file which will be used by the
270 JIT to display source lines for exceptions.
272 * list.unix: Disabled the dwarf file writer in the build.
274 2002-08-23 Martin Baulig <martin@gnome.org>
276 * MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Added
277 assembly name argument. Since the symbol writer needs to read the
278 final assembly, we need to give it its full pathname.
280 2002-08-23 Martin Baulig <martin@gnome.org>
282 * makefile.gnu, list.unix: Added.
284 2002-07-05 Martin Baulig <martin@gnome.org>
286 * MonoDwarfFileWriter.cs: Added support for types in referenced assemblies.
288 2002-07-05 Martin Baulig <martin@gnome.org>

301 corresponding struct/class declarations.
303 2002-06-28 Martin Baulig <martin@gnome.org>
305 * gdb-csharp-support.patch: Updated.
307 2002-06-28 Martin Baulig <martin@gnome.org>
309 * MonoDwarfFileWriter.cs: Use a TAG_string_type when we're using GNU extensions.
310 Make static struct/class fields actually work. Provide a TAG_typedef for struct's
313 2002-05-30 Martin Baulig <martin@gnome.org>
315 * IMonoSymbolWriter (IMonoSymbolWriter): Added custom `Initialize' method.
317 * MonoSymbolWriter.cs (Initialize): The ISymbolWriter's `Initialize' method
318 is no longer supported and throws an exception.
319 (Initialize (string, string[])): New custom initialization function.
321 * MonoDwarfFileWriter.cs (DwarfFileWriter): Added `string[] args' argument
322 to the constructor to pass command line arguments.
324 * gdb-csharp-support.patch: Updated for GDB 5.2.
326 2002-05-30 Martin Baulig <martin@gnome.org>
328 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now get's the
329 AssemblyBuilder's `methods' array as third argument.
330 (OpenMethod): Use this array to get the method builder rather than using an
332 (get_method_builder): Removed this interncall.
334 2002-05-25 Martin Baulig <martin@gnome.org>
336 * MonoDwarfFileWriter.cs: Finished the type rewrite, put back strings and arrays.
338 2002-05-24 Martin Baulig <martin@gnome.org>
340 * IMonoSymbolWriter.cs (ISourceMethod): Added `FullName' and `Parameters'.
341 (ITypeHandle): New interface.
343 * DwarfFileWriter.cs: Largely reorganized the type writing code. Types are
344 now represented by ITypeHandle objects which are stored in a per-dwarf-writer
345 hash table. At the moment, all types still need to be in one compile unit due
346 to lacking support in gdb - but this new type code here already supports this.
348 * MonoSymbolWriter.cs: Moved all the subclasses to the top-level and made them
349 public, cleaned up the code, put everything into one compile unit.
350 (DefineLocalVariable): Added a version of this function which takes useful args.
352 2002-05-22 Martin Baulig <martin@gnome.org>
354 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Added `Sources' and `Methods'
357 * MonoDwarfFileWriter.cs (WriteSymbolTable): New public method. Moved the
358 code that writes the "mono_line_numbers" section here from the LineNumberEngine.
360 2002-05-22 Martin Baulig <martin@gnome.org>
362 * IMonoSymbolWriter.cs (IVariable): Replaced Token with `ISourceMethod Method'.
364 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now has an additional
365 ModuleBuilder argument.
366 (OpenMethod): Immediately call the `get_method' interncall to get the MethodBase
367 from the token, then store the MethodBase instead of the token. The token may
368 still change during the metadata library's fixup process.
369 (DoFixups): When the image has been written to disk, call the GetToken () method
370 on all MethodBuilders and all ConstructorBuilders to get the final metadata tokens.
372 2002-05-22 Martin Baulig <martin@gnome.org>
374 * AssemblerWriterI386.cs: Don't use GNU extensions and produce assembler
375 output which is free of comments and extra whitespaces so that it's suitable
378 2002-05-22 Martin Baulig <martin@gnome.org>
380 * IMonoSymbolWriter.cs (ISourceMethod): Replaced `MethodInfo MethodInfo' with
381 `MethodBase MethodBase' and added `Type ReturnType'. We're now correctly
382 dealing with constructors and not crashing anymore.
384 2002-05-21 Martin Baulig <martin@gnome.org>
386 * MonoDwarfFileWriter.cs: Write a special line number table which can be read
387 in by the metadata library to get line number information in backtraces.
389 2002-05-06 Martin Baulig <martin@gnome.org>
391 * MonoSymbolWriter.cs (MonoSymbolWriter.Close): Use Assembly.LoadFrom (), not
392 AppDomain.Load () to load the assembly.
394 2002-04-26 Martin Baulig <martin@gnome.org>
396 * gdb-csharp-support.patch: A patch for GDB (against the latest CVS version)
397 to implement C# support.
399 * csharp-lang.c, csharp-lang.h, csharp-mono-lang.c: Copy these into your GDB
400 source directory after applying the patch.
402 2002-04-26 Martin Baulig <martin@gnome.org>
404 * MonoDwarfFileWriter.cs (DieInternalString): Removed.
406 2002-04-25 Martin Baulig <martin@gnome.org>
408 * MonoDwarfFileWriter.cs: Reflect latest MonoString changes.
410 2002-04-13 Martin Baulig <martin@gnome.org>
412 * IMonoSymbolWriter.cs (ISourceBlock): Added `Blocks' property and `AddBlock'
413 method to support nested blocks.
415 * MonoSymbolWriter.cs: Correctly handle nested blocks.
417 * MonoDwarfFileWriter.cs (DieMember): Provide info for all fields, not just for
418 public ones; also added DW_AT_accessibility.
419 (DieVariable): Reflected latest debug-symfile.c changes.
421 2002-04-12 Martin Baulig <martin@gnome.org>
423 * gdb-variable-scopes.patch: A patch for GDB (against the latest CVS version)
424 to implement variable lifetimes.
426 2002-04-12 Martin Baulig <martin@gnome.org>
428 * MonoDwarfFileWriter.cs (DieVariable): Provide info about the variable's
429 lifetime using DW_AT_begin_scope and a new baulig extension DW_AT_end_scope.
431 2002-03-29 Martin Baulig <martin@gnome.org>
433 * AssemblerWriterI386.cs: Rewrote most of the string output function, do the
434 number->string conversion manually. It's now taking about 15 seconds to write
435 a symbol file for MCS, no longer more than a minute.
437 * MonoDwarfFileWriter.cs: Added some profiling code, speeded things up, fixed
440 2002-03-25 Martin Baulig <martin@gnome.org>
442 * MonoDwarfFileWriter.cs (CreateType): Return a `DieType'.
443 (RegisterType): Add the type to the type hash before creating dependency types
444 so we don't get recursion loops.
445 (RegisterPointerType): New func to register a "pointer to type" type.
446 (DieTypeDef, DiePointerType, DieArrayType, DieStringType, DieClassType): New
447 types; added support for strings, arrays and basic support for classes.
449 2002-03-24 Martin Baulig <martin@gnome.org>
451 * IMonoSymbolWriter.cs: Killed all methods in this interface, no longer needed.
453 * MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now takes a string
454 argument which is the full pathname of the assembly - you must call Close()
455 after the assembly has been written to disk since the symbol writer needs to
456 load the finished assembly to get its metadata.
458 * MonoDwarfFileWriter.cs: Added support for enums and structs.
460 2002-03-24 Martin Baulig <martin@gnome.org>
462 * MonoDwarfFileWriter.cs: Added support for method parameters.
464 2002-03-24 Martin Baulig <martin@gnome.org>
466 * IMonoSymbolWriter.cs (IMonoSymbolWriter): Removed my custom OpenMethod(),
467 we're now using the ISymbolWriter's method.
468 (IVariable): Added `byte[] Signature' property.
470 * MonoSymbolWriter.cs (SetAssembly): New method. This must be called before
471 Close(); the assembly parameter is the already-written assembly, ie. it must
472 contain the full metadata.
473 (OpenMethod): Only take the token argument and set MethodInfo later in DoFixups.
474 (SetMethodSourceRange): You must call this function to tell the symbol writer
475 in which source file the method is defined.
476 (DefineLocal): Store the signature in the local.
477 (DoFixups): Use two new interncalls to set the SourceMethod's MethodInfo field
478 and the LocalVariable's Type field.
480 2002-03-23 Martin Baulig <martin@gnome.org>
482 * IMonoSymbolWriter.cs (ISourceBlock): New interface.
483 (ILocalVariable): Renamed this interface to IVariable.
484 (IVariable): Added Line, Type, Token.
485 (ILocalVariable, IMethodParameter): New interfaces, derive from IVariable.
486 (ISourceMethod): Added Blocks. Renamed FirstLine and LastLine to Start and End,
487 changed their type to ISourceLine. Removed CodeSize.
488 (ISourceLine): Renamed Line to Row, added Column. Added OffsetType and Offset.
490 * MonoDwarfFileWriter.cs (MonoDwarfFileWriter.DieLexicalBlock): New class.
491 (MonoDwarfFileWriter.DieMethodVariable): New class.
493 * MonoSymbolWriter.cs (OpenScope, CloseScope): Implemented.
494 Reflected latest IMonoSymbolWriter interface changes.
496 2002-03-20 Martin Baulig <martin@gnome.org>
498 * IAssemblerWriter.cs: New interface.
500 * AssemblerWriterI386.cs: New class.
502 * MonoDwarfFileWriter.cs: Use the IAssemblerWriter interface to make this class
503 platform and assembler independent.
505 2002-03-20 Martin Baulig <martin@gnome.org>
507 * IMonoSymbolWriter.cs (ISourceMethod): Added FirstLine, LastLine, CodeSize and
510 * MonoDwarfFileWriter.cs: Implemented line number support.
512 2002-03-19 Martin Baulig <martin@gnome.org>
514 * IMonoSymbolWriter.cs (ISourceFile, ISourceMethod, ISourceLine, ILocalVariable):
517 * IMonoSymbolWriter.cs (OpenMethod): Take a System.Reflection.MethodInfo, not
520 2002-03-19 Martin Baulig <martin@gnome.org>
522 This is an implementation of the System.Diagnostics.SymbolStore.SymbolWriter
523 interface. It's still work in progress and not yet used anywhere.
525 There is some preliminary documentation in the source files and some more
526 docu in the README and README.relocation-table files.
528 * IMonoSymbolWriter.cs: New file.
529 * MonoDwarfFileWriter.cs: New file.
530 * MonoSymbolDocumentWriter.cs: New file.
