* Added class ValueLocation to represent a location of a value on the target machine. * DWARF: - Various additions to the DIE classes. - DwarfExpressionEvaluationContext: - Added support for location expressions and thus the missing DW_OP_piece and DW_OP_bit_piece operations. - Fixed some deviations from the specs. - Added debug output. - DwarfFile: - Added missing evaluation of CFA expression rules. - Added service methods to evaluate expressions, location expressions, and constant and dynamic values. * Added model classes for representing types and variables. Particularly the types part is not finished yet. * StackFrame does now contain parameters and local variables. * Added DwarfInterfaceFactory, which creates implementation objects for the types, as well as variables objects. It's even less finished. * DwarfImageDebugInfo::CreateFrame(): Resolve function parameters and add them to the stack frame. No local variables yet. * Added the beginnings of a variables view. Only lists the names of parameters and local variables (of understood types) ATM. * Renamed RegisterView to RegistersView. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31614 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

* 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

Retrieve the source file declaration locations for functions and attach them to the DwarfFunctionDebugInfo objects. The functions do now appear organized by source file in the function list view. Unfortunately the list view is too small to look as clear as it should. Got to think of something else I'm afraid. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31326 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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
