¶bool dumpName(
    llvm::ScopedPrinter& W,
    SmallVectorImpl<llvm::DWARFFormValue>&
        AtomForms,
    uint64_t* DataOffset) const

Description

Returns true if we should continue scanning for entries or false if we've reached the last (sentinel) entry of encountered a parsing error.

Parameters

llvm::ScopedPrinter& W

SmallVectorImpl<llvm::DWARFFormValue>& AtomForms

equal_range(llvm::StringRef Key) const

Description

Look up all entries in the accelerator table matching \c Key.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAcceleratorTable.h:207

Parameters

llvm::StringRef Key

¶ArrayRef<std::pair<HeaderData::AtomType,
                   HeaderData::Form>>
getAtomsDesc()

Description

Return the Atom description, which can be used to interpret the raw values of the Accelerator Entries in this table.

    uint64_t* HashDataOffset)

Description

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

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAcceleratorTable.h:203

Parameters

uint64_t* HashDataOffset

an 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
