¶Optional<uint32_t> findAttributeIndex(
    dwarf::Attribute attr) const

Description

Get the index of the specified attribute. Searches the this abbreviation declaration for the index of the specified attribute.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAbbreviationDeclaration.h:121

Parameters

dwarf::Attribute attr

DWARF attribute to search for.

Returns

Optional index of the attribute if found, None otherwise.

Parameters

uint32_t idx

¶Optional<llvm::DWARFFormValue> getAttributeValue(
    const uint64_t DIEOffset,
    const dwarf::Attribute Attr,
    const llvm::DWARFUnit& U) const

Description

Extract a DWARF form value from a DIE specified by DIE offset. Extract an attribute value for a DWARFUnit given the DIE offset and the attribute.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAbbreviationDeclaration.h:133

Parameters

const uint64_t DIEOffset

the DIE offset that points to the ULEB128 abbreviation code in the .debug_info data.

const dwarf::Attribute Attr

DWARF attribute to search for.

const llvm::DWARFUnit& U

the DWARFUnit the contains the DIE.

Returns

Optional DWARF form value if the attribute was extracted.
