Summary:
Summary: Update DWARF location lists in .debug_loc and pointers to
them in .debug_info so that gdb can print variables which change
location during their lifetime.
The following changes were made:
- Refactored BasicBlockOffsetRanges to allow ranges to be tied to binary information (so that we can reuse it for location lists)
- Implemented range compression optimization in BasicBlockOffsetRanges (needed otherwise too much data was being generated).
- Added representation for location lists (LocationList.h, BinaryContext.h)
- Implemented .debug_loc serializer that keeps the updated offsets (DebugLocWriter.{h,cpp})
- After disassembly, traverse entries in .debug_loc and save them in context (BinaryContext.cpp)
- After optimizations, serialize .debug_loc and update pointers in .debug_info (RewriteInstance.cpp)
