Classes
class	llvm::memprof::CallStackTrie
	Class to build a trie of call stack contexts for a particular profiled allocation call, along with their associated allocation types. More...
class	llvm::memprof::CallStack< NodeT, IteratorT >
	Helper class to iterate through stack ids in both metadata (memprof MIB and callsite) and the corresponding ThinLTO summary data structures (CallsiteInfo and MIBInfo). More...
struct	llvm::memprof::CallStack< NodeT, IteratorT >::CallStackIterator

Functions
LLVM_ABI bool	llvm::memprof::metadataIncludesAllContextSizeInfo ()
	Whether the alloc memeprof metadata will include context size info for all MIBs.
LLVM_ABI bool	llvm::memprof::metadataMayIncludeContextSizeInfo ()
	Whether the alloc memprof metadata may include context size info for some MIBs (but possibly not all).
LLVM_ABI bool	llvm::memprof::recordContextSizeInfoForAnalysis ()
	Whether we need to record the context size info in the alloc trie used to build metadata.
LLVM_ABI MDNode *	llvm::memprof::buildCallstackMetadata (ArrayRef< uint64_t > CallStack, LLVMContext &Ctx)
	Build callstack metadata from the provided list of call stack ids.
LLVM_ABI MDNode *	llvm::memprof::buildContextSizeMetadata (ArrayRef< ContextTotalSize > ContextSizeInfo, LLVMContext &Ctx)
	Build metadata from the provided list of full stack id and profiled size, to use when reporting of hinted sizes is enabled.
LLVM_ABI MDNode *	llvm::memprof::getMIBStackNode (const MDNode *MIB)
	Returns the stack node from an MIB metadata node.
LLVM_ABI AllocationType	llvm::memprof::getMIBAllocType (const MDNode *MIB)
	Returns the allocation type from an MIB metadata node.
LLVM_ABI std::string	llvm::memprof::getAllocTypeAttributeString (AllocationType Type)
	Returns the string to use in attributes with the given type.
LLVM_ABI bool	llvm::memprof::hasSingleAllocType (uint8_t AllocTypes)
	True if the AllocTypes bitmask contains just a single type.
LLVM_ABI void	llvm::memprof::removeAnyExistingAmbiguousAttribute (CallBase *CB)
	Removes any existing "ambiguous" memprof attribute.
LLVM_ABI void	llvm::memprof::addAmbiguousAttribute (CallBase *CB)
	Adds an "ambiguous" memprof attribute to call with a matched allocation profile but that we haven't yet been able to disambiguate.
