* Added DebuggerInterface::GetSymbolInfos() to get the symbols for an image. * Added the beginnings of the debug info abstraction. Currently we can only load the symbols via the debugger. * Added a job to retrieve debug info for an image. Extended the GetStackTraceJob to support waiting for image debug info to be loaded. * Extended ImageInfo by text/data address and size. * Removed StackFrameX86 and made StackFrame a simple non-polymorphic class featuring all the needed data. The really architecture-dependent is in the referenced CpuState already. Added Image* and FunctionDebugInfo* attributes, referring to the image respectively debug info for the function hit by the instruction pointer. * Switched StrackTrace's StackFrame management from DoublyLinkedList to BObjectList. This makes it more comfortable to use. * Changed the code for creating stack traces: - The creation of the StackTrace object and the main loop to collect the frames are now located in the no longer virtual Architecture::CreateStackTrace(). - The decision how to create a StackFrame is based on the instruction pointer. If it hit a function for which debug info is available, the respective DebugInfo::CreateStackFrame() is used, otherwise we fall back to the new virtual Architecture::CreateStackFrame(). * Adjusted the stack trace view to also show function names (mangled ATM). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31142 a95241bf-73f2-0310-859d-f6bbb57e9c96

#include "SourceLocation.h"
* Renamed ArchitectureTypes.h to Types.h. * Created "types" subdirectory for basic types and moved Types.h, SourceLocation, TargetAddressRange there. * Added TargetAddressRangeList, representing a list of address ranges. * Array: Added copy constructor and assignment operator. * Added DwarfFunctionDebugInfo. * ElfFile: Also read the program headers and provide access to the segment information. * DWARF: - Some work on DIECompileUnitBase and DIESubprogram to handle attributes we need. - Added DwarfUtils class which provides static utility methods. Currently some to get DIE names. Only provisionally implemented yet. - Read range list attribute values from the .debug_ranges section. Extended AttributeValue to handle them correctly (ref-counting). * DwarfImageDebugInfo: - Implemented GetFunctions() for real, i.e. we return functions for all subprogram debug info entries we find (those that refer to actual functions, that is). - Implemented the fallback part of LoadSourceCode() (reading the code from the file and disassembling it). Things should hopefully work as before, just a bit slower and with less accurate function names, if DWARF debug info is available. Promising, eh? ;-) git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31321 a95241bf-73f2-0310-859d-f6bbb57e9c96

Very much work in progress, not in a particularly working state. Haiku munged a good part of the source tree, so I rather get those changes into the repository before continuing. The general aim of the work is to deal with multiple instances of the same function, e.g. inlined or non-inlined inline functions or those weird duplicates gcc (4 at least) seems to be generating for no apparent reason. * Added classes FunctionInstance (wrapping FunctionDebugInfo) and Function. FunctionInstance represents a physical instance of a function (e.g. inlined function at a particular address). A Function collects all FunctionInstances referring to the same source code location. * Moved the SourceCode property from FunctionDebugInfo to Function accordingly. * Since SourceCode is no longer associated with a concrete function instance, several methods dealing with statements have been removed and the functionality has been provided through other means (e.g. TeamDebugModel or SpecificImageDebugModel). This part is not yet completed. * Introduced UserBreakpoint and UserBreakpointInstance. The user sets a breakpoint at a source code location, which is represented by a UserBreakpoint. Since that source location can be mapped to one address per instance of the respective function, UserBreakpoint has a UserBreakpointInstance per such function instance, which in turn refers to a Breakpoint (an actual breakpoint at an address). * Adjusted Breakpoint, BreakpointManager, and TeamDebugger accordingly. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31447 a95241bf-73f2-0310-859d-f6bbb57e9c96

class BString;
* DWARF: - DwarfUtils::GetDeclarationLocation(): Line/column numbers are one-based. - Added line number program interpretation (LineNumberProgram). * FunctionDebugInfo: Return the source file (LocatableFile) instead of the file name. * FileManager/LocatableEntry: Fixed handling when a LocatableEntry is unreferenced. There was a race condition before, since an unreferenced entry could be referenced and unreferenced again before removing it from the hash table, which could lead to double deletion. Now we never reuse an unreferenced entry and just remove it from the hash table when encountering one. * FileManager/SourceFile: Added class SourceFile which loads a source file from disk and slices it into lines. Managed by FileManager. * Added class FileSourceCode, a SourceCode implementation using a SourceFile as line provider. The statement management works pretty much exactly as in DissassembledCode. * DwarfImageDebugInfo: Implemented LoadSourceCode for real. It creates a FileSourceCode and uses the DWARF line number information for the statement information. This basically gets the source level view going, though there are still several problems -- stepping doesn't work perfectly yet, the source isn't found for all functions, there's no handling of duplicate functions (no idea why gcc generates them in the first place), etc. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31382 a95241bf-73f2-0310-859d-f6bbb57e9c96

Debugger: Extend FunctionDebugInfo interface. - Add hook to FunctionDebugInfo to determine if the represented function is the main function of the program. Adjust {Basic,Dwarf}FunctionDebugInfo accordingly. - {Team,Image}DebugInfo: When loading, see if the current image contains the main function. If so, cache it for later retrieval.
