toSectionOffset() [2/2]

uint64_t llvm::dwarf::toSectionOffset ( const Optional< DWARFFormValue > &  V, uint64_t  Default  )

inline

Take an optional DWARFFormValue and extract a section offset.

Parameters

V	and optional DWARFFormValue to attempt to extract the value from.
Default	the default value to return in case of failure.

Returns

the extracted section offset value or Default if the V doesn't have a value or the form value's encoding wasn't a section offset form.

toSigned() [1/2]

Optional<int64_t> llvm::dwarf::toSigned ( const Optional< DWARFFormValue > &  V )

inline

Take an optional DWARFFormValue and try to extract an signed constant.

Parameters

V	and optional DWARFFormValue to attempt to extract the value from.

Returns

an optional value that contains a value if the form value was valid and has a signed constant form.

Parameters

V	and optional DWARFFormValue to attempt to extract the value from.
Default	the default value to return in case of failure.

Returns

the extracted signed integer value or Default if the V doesn't have a value or the form value's encoding wasn't a signed integer form.
