- 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.
