Definition at line 131 of file DebugLocEntry.h.

References llvm::all_of(), llvm::SmallVectorImpl< T >::append(), assert(), llvm::ArrayRef< T >::begin(), llvm::ArrayRef< T >::end(), llvm::DebugLocEntry::Value::isFragment(), and sortUniqueValues().

finalize()

void DebugLocEntry::finalize	(	const AsmPrinter &	AP,
		DebugLocStream::ListBuilder &	List,
		const DIBasicType *	BT
	)

getBeginSym()

const MCSymbol* llvm::DebugLocEntry::getBeginSym ( ) const

inline

Definition at line 128 of file DebugLocEntry.h.

getEndSym()

const MCSymbol* llvm::DebugLocEntry::getEndSym ( ) const

inline

Definition at line 129 of file DebugLocEntry.h.

getValues()

ArrayRef<Value> llvm::DebugLocEntry::getValues ( ) const

inline

Definition at line 130 of file DebugLocEntry.h.

MergeRanges()

bool llvm::DebugLocEntry::MergeRanges ( const DebugLocEntry &  Next )

inline

Attempt to merge this DebugLocEntry with Next and return true if the merge was successful.

Entries can be merged if they share the same Loc/Constant and if Next immediately follows this Entry.

Definition at line 119 of file DebugLocEntry.h.

MergeValues()

bool DebugLocEntry::MergeValues

(

const DebugLocEntry &

Next

)

If this and Next are describing different pieces of the same variable, merge them by appending Next's values to the current list of values.

If this and Next are describing different fragments of the same variable, merge them by appending Next's values to the current list of values.

Return true if the merge was successful.
