◆ readAtoms()

std::pair< uint64_t, dwarf::Tag > AppleAcceleratorTable::readAtoms ( uint64_t HashDataOffset)

Return information related to the DWARF DIE we're looking for when performing a lookup by name.

Parameters
HashDataOffsetan offset into the hash data table
Returns
<DieOffset, DieTag> DieOffset is the offset into the .debug_info section for the DIE related to the input hash data offset. DieTag is the tag of the DIE
