Detailed Description

Multimap-like storage for metadata attachments for globals.

This differs from MDAttachmentMap in that it allows multiple attachments per metadata kind.

References I, and llvm::remove_if().

get()

void MDGlobalAttachmentMap::get	(	unsigned	ID,
		SmallVectorImpl< MDNode *> &	Result
	)		const

Appends all attachments with the given ID to Result in insertion order.

If the global has no attachments with the given ID, or if ID is invalid, leaves Result unchanged.

Definition at line 1161 of file Metadata.cpp.

References llvm::SmallVectorTemplateBase< T >::push_back().

getAll()

void MDGlobalAttachmentMap::getAll

(

SmallVectorImpl< std::pair< unsigned, MDNode *>> &

Result

)

const

Appends all attachments for the global to Result, sorting by attachment ID.

Attachments with the same ID appear in insertion order. This function does not clear Result.

Definition at line 1176 of file Metadata.cpp.

References B.

insert()

void MDGlobalAttachmentMap::insert	(	unsigned	ID,
		MDNode &	MD
	)

Definition at line 1150 of file Metadata.cpp.

lookup()

MDNode * MDGlobalAttachmentMap::lookup

(

unsigned

ID

)

const

Returns the first attachment with the given ID or nullptr if no such attachment exists.
