AddressesMap represents information about valid addresses used by debug information.
Valid addresses are those which points to live code sections. i.e. relocations for these addresses point into sections which would be/are placed into resulting binary.

◆ applyValidRelocs()
Apply the valid relocations to the buffer Data, taking into account that Data is at BaseOffset in the .debug_info section.
Returns
true whether any reloc has been applied.
References llvm::Data.
◆ clear()
| virtual void llvm::dwarf_linker::AddressesMap::clear ( ) | pure virtual |
|---|
Erases all data.
◆ getExprOpAddressRelocAdjustment()
Checks that the specified DWARF expression operand [Op](namespacellvm.html#ab471937b9a227e70c7fe8bd9604014d6) references live code section and returns the relocation adjustment value (to get the linked address this value might be added to the source expression operand address).
Print debug output if Verbose is true.
Returns
relocation adjustment value or std::nullopt if there is no corresponding live address.
References llvm::Verbose.

◆ getSubprogramRelocAdjustment()
| virtual std::optional< int64_t > llvm::dwarf_linker::AddressesMap::getSubprogramRelocAdjustment ( const DWARFDie & DIE, bool Verbose ) | pure virtual |
|---|
Checks that the specified subprogram [DIE](classllvm%5F1%5F1DIE.html "A structured debug information entry.") references the live code section and returns the relocation adjustment value (to get the linked address this value might be added to the source subprogram address).
Allowed kinds of input DIE: DW_TAG_subprogram, DW_TAG_label. Print debug output if Verbose is true.
Returns
relocation adjustment value or std::nullopt if there is no corresponding live address.
