Detailed Description

Tuple of metadata.

This is the simple MDNode arbitrary tuple. Nodes are uniqued by default based on their operands.

clone()

TempMDTuple llvm::MDTuple::clone ( ) const

inline

Return a (temporary) clone of this.

filter()

template<typename T>

MDTuple * llvm::MDTuple::filter ( T && Pred )

inline

Filter out tuple elements that do not satisfy predicate.

Return this if no elements should be filtered out (without re-uniquing).

Return a distinct node – i.e., a node that is not uniqued.

getTemporary()

TempMDTuple llvm::MDTuple::getTemporary ( LLVMContext & Context, ArrayRef< Metadata * > MDs )

inlinestatic
