JDevlieghere added inline comments.
================
Comment at: lldb/include/lldb/Expression/DWARFExpression.h:260
- bool GetLocation(lldb::addr_t func_load_addr, lldb::addr_t pc,
- lldb::offset_t &offset, lldb::offset_t &len);
+ void RelocateLowHighPC(lldb::addr_t load_function_start, lldb::addr_t &low_pc,
+ lldb::addr_t &high_pc) const;
----------------
Should this be part of the DWARFExpression API? It feels like a static function might be sufficient. Maybe it could take a range directly?
================
Comment at: lldb/source/Expression/DWARFExpression.cpp:53
+ if (data.ValidOffsetForDataOfSize(offset, index_size))
+ return data.GetMaxU64_unchecked(&offset, index_size);
+ return LLDB_INVALID_ADDRESS;
----------------
Why the unchecked?
================
Comment at: lldb/source/Expression/DWARFExpression.cpp:158
+
+ llvm::MCRegisterInfo *MRI = nullptr;
+ if (abi)
----------------
``` llvm::MCRegisterInfo *MRI = abi ? &abi->GetMCRegisterInfo() : nullptr;```
================
Comment at: lldb/source/Expression/DWARFExpression.cpp:2799
+ addr_t &high_pc) const {
+ // This relocates low_pc and high_pc by adding the difference between the
+ // function file address, and the actual address it is loaded in memory.
----------------
Should this be a doxygen comment on the function itself?
