(MonoSymbolFile.Guid): New public property.
2006-09-24 Joshua Tauberer <>

* MonoSymbolFile.cs (CreateSymbolFile): Take a filestream to
write to. Do not return a byte array.
(MyMemoryStream): Unused now.
* MonoSymbolWriter.cs: Take advantage of the api change above.
Overall, this prevents us from having to allocate the debug file

over 3 mb (you must write it in chunks then get the big array)
With the file stream, it takes up 4 kb or so for the buffer.

2004-08-27 Martin Baulig <>
* MonoSymbolFile.cs (MonoDebuggerSupport.GetGuid): The function is
called Module.Mono_GetGuid(), not Module.MonoDebugger_GetGuid().
2004-07-30 Martin Baulig <>
The library is now called Mono.CompilerServices.SymbolWriter.dll
and is in the Mono.CompilerServices.SymbolWriter namespace.
* MonoSymbolFile.cs (MonoDebuggerSupport.GetGuid): New public
static method.

information from an external ".mdb" file.
* MonoSymbolTable.cs

(MethodEntry.ParamTypeIndicies): Likewise.
2004-07-02 Raja R Harinath <>
2004-06-24 Raja R Harinath <>

* MonoSymbolTable.cs (MethodEntry): Don't write the method's full
name into the symbol file.
2004-01-16 Martin Baulig <>
* MonoSymbolFile.cs (MonoDebuggerSupport): As suggested by Ben
Maurer, create a delegate type for each of the methods and then
store the method.
2004-01-15 Martin Baulig <>
* MonoSymbolFile.cs (MonoDebuggerSupport): New public class
containing static wrappers for calling the `MonoDebugger_*'
function in S.R.Assembly.

* ChangeLog, MonoSymbolTable.cs: Reviewed Ben's patches. For
those which are not ok, I'll add detailed comments to the source
2003-12-28 Ben Maurer <>
[Revision 1.41, not approved. Martin]

* MonoSymbolTable.cs (MethodEntry): Remove the
SourceFileIndex field, we already have the info.
2003-12-28 Ben Maurer <>
[Revision 1.39, approved. Martin]
* MonoSymbolTable.cs: Don't make the MethodIndexEntry
part of the method entry class, because it just
takes up extra space.
2003-12-28 Ben Maurer <>
[Revisions 1.37 and 1.38; not approved. Martin]
* MonoSymbolTable.cs (MethodEntry.BuildLineNumberTable): Removed.

* MonoSymbolWriter.cs: Create ArrayLists only when needed.
2003-12-07 Ben Maurer <>
[Revision 1.35, approved. Martin]
* MonoSymbolTable.cs: It is faster to do a linear search
than it is to make a hashtable. Even though the linear
search is O(n^2) while the hashtable is O(n), the allocation
cost for a hashtable is *very* high, especially when only
a few members will be added.

debugger that a local variable is only available in a specific
lexical scope and that another variable of the same name may exist
in another lexical scope. See debugger/test/TestLexicalScope.cs
for examples.
* MonoSymbolTable.cs (LexicalScopeEntry): New class.
(LocalVariableEntry): Added `BlockIndex' field which specifies the
lexical scope of this variable.

* passing the /r using an 'arg' node works.
The <include> node wasn't getting to the compiler. This fixes build
breakage on cygwin.

(NamespaceEntry): New struct.
(SourceFileEntry.DefineNamespace): New method.

custom initialization function.
* MonoSymbolTableWriter.cs: Removed; the code is now in
MonoSymbolFile.cs and MonoSymbolWriter.cs.
2003-02-07 Martin Baulig <>

assembly instead of a separate file.
* MonoSymbolTable.cs: Did a few more cleanups, sort the line
number table and remove duplicate line numbers.
2003-02-05 Martin Baulig <>
Modified the symbol file format to speed up method looks by name
and cleaned this up a lot.

* MonoSymbolWriter.cs (MonoSymbolWriter.Initialize): Added
assembly name argument. Since the symbol writer needs to read the
final assembly, we need to give it its full pathname.
2002-08-23 Martin Baulig <>
* makefile.gnu, list.unix: Added.
2002-07-05 Martin Baulig <>
* MonoDwarfFileWriter.cs: Added support for types in referenced assemblies.
2002-07-05 Martin Baulig <>
* MonoDwarfFileWriter.cs: Added support for arrays.
* gdb-csharp-support.patch: Updated.
2002-06-29 Martin Baulig <>
* MonoDwarfFileWriter.cs (DieInheritance): Make this actually work.
2002-06-29 Martin Baulig <>
* MonoDwarfFileWriter.cs, MonoSymbolWriter.cs: Put all TAG_subprogram's into their
corresponding struct/class declarations.
2002-06-28 Martin Baulig <>
* gdb-csharp-support.patch: Updated.
2002-06-28 Martin Baulig <>
* MonoDwarfFileWriter.cs: Use a TAG_string_type when we're using GNU extensions.
Make static struct/class fields actually work. Provide a TAG_typedef for struct's
and classes.
2002-05-30 Martin Baulig <>
* IMonoSymbolWriter (IMonoSymbolWriter): Added custom `Initialize' method.
* MonoSymbolWriter.cs (Initialize): The ISymbolWriter's `Initialize' method
is no longer supported and throws an exception.
(Initialize (string, string[])): New custom initialization function.
* MonoDwarfFileWriter.cs (DwarfFileWriter): Added `string[] args' argument
to the constructor to pass command line arguments.
* gdb-csharp-support.patch: Updated for GDB 5.2.
2002-05-30 Martin Baulig <>
* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now get's the
AssemblyBuilder's `methods' array as third argument.
(OpenMethod): Use this array to get the method builder rather than using an
interncall for it.
(get_method_builder): Removed this interncall.
2002-05-25 Martin Baulig <>
* MonoDwarfFileWriter.cs: Finished the type rewrite, put back strings and arrays.
2002-05-24 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceMethod): Added `FullName' and `Parameters'.
(ITypeHandle): New interface.
* DwarfFileWriter.cs: Largely reorganized the type writing code. Types are
now represented by ITypeHandle objects which are stored in a per-dwarf-writer
hash table. At the moment, all types still need to be in one compile unit due
to lacking support in gdb - but this new type code here already supports this.
* MonoSymbolWriter.cs: Moved all the subclasses to the top-level and made them
public, cleaned up the code, put everything into one compile unit.
(DefineLocalVariable): Added a version of this function which takes useful args.
2002-05-22 Martin Baulig <>
* IMonoSymbolWriter.cs (IMonoSymbolWriter): Added `Sources' and `Methods'
* MonoDwarfFileWriter.cs (WriteSymbolTable): New public method. Moved the
code that writes the "mono_line_numbers" section here from the LineNumberEngine.
2002-05-22 Martin Baulig <>
* IMonoSymbolWriter.cs (IVariable): Replaced Token with `ISourceMethod Method'.
* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now has an additional
ModuleBuilder argument.
(OpenMethod): Immediately call the `get_method' interncall to get the MethodBase
from the token, then store the MethodBase instead of the token. The token may
still change during the metadata library's fixup process.
(DoFixups): When the image has been written to disk, call the GetToken () method
on all MethodBuilders and all ConstructorBuilders to get the final metadata tokens.
2002-05-22 Martin Baulig <>
* AssemblerWriterI386.cs: Don't use GNU extensions and produce assembler
output which is free of comments and extra whitespaces so that it's suitable
for `as -f'.
2002-05-22 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceMethod): Replaced `MethodInfo MethodInfo' with
`MethodBase MethodBase' and added `Type ReturnType'. We're now correctly
dealing with constructors and not crashing anymore.
2002-05-21 Martin Baulig <>
* MonoDwarfFileWriter.cs: Write a special line number table which can be read
in by the metadata library to get line number information in backtraces.
2002-05-06 Martin Baulig <>
* MonoSymbolWriter.cs (MonoSymbolWriter.Close): Use Assembly.LoadFrom (), not
AppDomain.Load () to load the assembly.
2002-04-26 Martin Baulig <>
* gdb-csharp-support.patch: A patch for GDB (against the latest CVS version)
to implement C# support.
* csharp-lang.c, csharp-lang.h, csharp-mono-lang.c: Copy these into your GDB
source directory after applying the patch.
2002-04-26 Martin Baulig <>
* MonoDwarfFileWriter.cs (DieInternalString): Removed.
2002-04-25 Martin Baulig <>
* MonoDwarfFileWriter.cs: Reflect latest MonoString changes.
2002-04-13 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceBlock): Added `Blocks' property and `AddBlock'
method to support nested blocks.
* MonoSymbolWriter.cs: Correctly handle nested blocks.
* MonoDwarfFileWriter.cs (DieMember): Provide info for all fields, not just for
public ones; also added DW_AT_accessibility.
(DieVariable): Reflected latest debug-symfile.c changes.
2002-04-12 Martin Baulig <>
* gdb-variable-scopes.patch: A patch for GDB (against the latest CVS version)
to implement variable lifetimes.
2002-04-12 Martin Baulig <>
* MonoDwarfFileWriter.cs (DieVariable): Provide info about the variable's
lifetime using DW_AT_begin_scope and a new baulig extension DW_AT_end_scope.
2002-03-29 Martin Baulig <>
* AssemblerWriterI386.cs: Rewrote most of the string output function, do the
number->string conversion manually. It's now taking about 15 seconds to write
a symbol file for MCS, no longer more than a minute.
* MonoDwarfFileWriter.cs: Added some profiling code, speeded things up, fixed
a few bugs.
2002-03-25 Martin Baulig <>
* MonoDwarfFileWriter.cs (CreateType): Return a `DieType'.
(RegisterType): Add the type to the type hash before creating dependency types
so we don't get recursion loops.
(RegisterPointerType): New func to register a "pointer to type" type.
(DieTypeDef, DiePointerType, DieArrayType, DieStringType, DieClassType): New
types; added support for strings, arrays and basic support for classes.
2002-03-24 Martin Baulig <>
* IMonoSymbolWriter.cs: Killed all methods in this interface, no longer needed.
* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now takes a string
argument which is the full pathname of the assembly - you must call Close()
after the assembly has been written to disk since the symbol writer needs to
load the finished assembly to get its metadata.
* MonoDwarfFileWriter.cs: Added support for enums and structs.
2002-03-24 Martin Baulig <>
* MonoDwarfFileWriter.cs: Added support for method parameters.
2002-03-24 Martin Baulig <>
* IMonoSymbolWriter.cs (IMonoSymbolWriter): Removed my custom OpenMethod(),
we're now using the ISymbolWriter's method.
(IVariable): Added `byte[] Signature' property.
* MonoSymbolWriter.cs (SetAssembly): New method. This must be called before
Close(); the assembly parameter is the already-written assembly, ie. it must
contain the full metadata.
(OpenMethod): Only take the token argument and set MethodInfo later in DoFixups.
(SetMethodSourceRange): You must call this function to tell the symbol writer
in which source file the method is defined.
(DefineLocal): Store the signature in the local.
(DoFixups): Use two new interncalls to set the SourceMethod's MethodInfo field
and the LocalVariable's Type field.
2002-03-23 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceBlock): New interface.
(ILocalVariable): Renamed this interface to IVariable.
(IVariable): Added Line, Type, Token.
(ILocalVariable, IMethodParameter): New interfaces, derive from IVariable.
(ISourceMethod): Added Blocks. Renamed FirstLine and LastLine to Start and End,
changed their type to ISourceLine. Removed CodeSize.
(ISourceLine): Renamed Line to Row, added Column. Added OffsetType and Offset.
* MonoDwarfFileWriter.cs (MonoDwarfFileWriter.DieLexicalBlock): New class.
(MonoDwarfFileWriter.DieMethodVariable): New class.
* MonoSymbolWriter.cs (OpenScope, CloseScope): Implemented.
Reflected latest IMonoSymbolWriter interface changes.
2002-03-20 Martin Baulig <>
* IAssemblerWriter.cs: New interface.
* AssemblerWriterI386.cs: New class.
* MonoDwarfFileWriter.cs: Use the IAssemblerWriter interface to make this class
platform and assembler independent.
2002-03-20 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceMethod): Added FirstLine, LastLine, CodeSize and
Token properties.
* MonoDwarfFileWriter.cs: Implemented line number support.
2002-03-19 Martin Baulig <>
* IMonoSymbolWriter.cs (ISourceFile, ISourceMethod, ISourceLine, ILocalVariable):
New interfaces.
* IMonoSymbolWriter.cs (OpenMethod): Take a System.Reflection.MethodInfo, not
a string.
2002-03-19 Martin Baulig <>
