Function Documentation

LLVMGetMDNodeNumOperands()

unsigned LLVMGetMDNodeNumOperands

(

LLVMValueRef

V

)

Obtain the number of operands from an MDNode value.

Parameters

V	MDNode to get number of operands from.

Returns

Number of operands of the MDNode.

LLVMGetMDNodeOperands()

void LLVMGetMDNodeOperands	(	LLVMValueRef	V,
		LLVMValueRef *	Dest
	)

Obtain the given MDNode's operands.

The passed LLVMValueRef pointer should point to enough memory to hold all of the operands of the given MDNode (see LLVMGetMDNodeNumOperands) as LLVMValueRefs. This memory will be populated with the LLVMValueRefs of the MDNode's operands.

Parameters

V	MDNode to get the operands from.
Dest	Destination array for operands.

LLVMGetMDString()

const char * LLVMGetMDString	(	LLVMValueRef	V,
		unsigned *	Length
	)

Obtain the underlying string from a MDString value.

Parameters

V	Instance to obtain string from.
Length	Memory address which will hold length of returned string.

Returns

String data in MDString.

LLVMMDNode()

LLVMValueRef LLVMMDNode	(	LLVMValueRef *	Vals,
		unsigned	Count
	)

Deprecated: Use LLVMMDNodeInContext2 instead.

LLVMMDNodeInContext()

LLVMValueRef LLVMMDNodeInContext	(	LLVMContextRef	C,
		LLVMValueRef *	Vals,
		unsigned	Count
	)

Deprecated: Use LLVMMDNodeInContext2 instead.

LLVMMDNodeInContext2()

LLVMMetadataRef LLVMMDNodeInContext2	(	LLVMContextRef	C,
		LLVMMetadataRef *	MDs,
		size_t	Count
	)

Create an MDNode value with the given array of operands.

llvm::MDNode::get()

LLVMMDString()

LLVMValueRef LLVMMDString	(	const char *	Str,
		unsigned	SLen
	)

Deprecated: Use LLVMMDStringInContext2 instead.

LLVMMDStringInContext()

LLVMValueRef LLVMMDStringInContext	(	LLVMContextRef	C,
		const char *	Str,
		unsigned	SLen
	)

Deprecated: Use LLVMMDStringInContext2 instead.

LLVMMDStringInContext2()

LLVMMetadataRef LLVMMDStringInContext2	(	LLVMContextRef	C,
		const char *	Str,
		size_t	SLen
	)

Create an MDString value from a given string value.

The MDString value does not take ownership of the given string, it remains the responsibility of the caller to free it.

llvm::MDString::get()

LLVMMetadataAsValue()

LLVMValueRef LLVMMetadataAsValue	(	LLVMContextRef	C,
		LLVMMetadataRef	MD
	)

Obtain a Metadata as a Value.

LLVMReplaceMDNodeOperandWith()

void LLVMReplaceMDNodeOperandWith	(	LLVMValueRef	V,
		unsigned	Index,
		LLVMMetadataRef	Replacement
	)

Replace an operand at a specific index in a llvm::MDNode value.

LLVMValueAsMetadata()

LLVMMetadataRef LLVMValueAsMetadata

(

LLVMValueRef

Val

)

Obtain a Value as a Metadata.
