Function Documentation

LLVMAddIncoming()

void LLVMAddIncoming	(	LLVMValueRef	PhiNode,
		LLVMValueRef *	IncomingValues,
		LLVMBasicBlockRef *	IncomingBlocks,
		unsigned	Count
	)

Add an incoming value to the end of a PHI list.

Here is the caller graph for this function:

LLVMCountIncoming()

unsigned LLVMCountIncoming

(

LLVMValueRef

PhiNode

)

Obtain the number of incoming basic blocks to a PHI node.

LLVMGetIncomingBlock()

LLVMBasicBlockRef LLVMGetIncomingBlock	(	LLVMValueRef	PhiNode,
		unsigned	Index
	)

Obtain an incoming value to a PHI node as an LLVMBasicBlockRef.

LLVMGetIncomingValue()

LLVMValueRef LLVMGetIncomingValue	(	LLVMValueRef	PhiNode,
		unsigned	Index
	)

Obtain an incoming value to a PHI node as an LLVMValueRef.
