Function Documentation

LLVMGetCondition()

LLVMValueRef LLVMGetCondition

(

LLVMValueRef

Branch

)

Return the condition of a branch instruction.

This only works on llvm::BranchInst instructions.

See also

llvm::BranchInst::getCondition

LLVMGetNumSuccessors()

unsigned LLVMGetNumSuccessors

(

LLVMValueRef

Term

)

Return the number of successors that this terminator has.

See also

llvm::Instruction::getNumSuccessors

LLVMGetSuccessor()

LLVMBasicBlockRef LLVMGetSuccessor	(	LLVMValueRef	Term,
		unsigned	i
	)

Return the specified successor.

llvm::Instruction::getSuccessor

LLVMGetSwitchDefaultDest()

LLVMBasicBlockRef LLVMGetSwitchDefaultDest

(

LLVMValueRef

SwitchInstr

)

Obtain the default destination basic block of a switch instruction.

This only works on llvm::SwitchInst instructions.

See also

llvm::SwitchInst::getDefaultDest()

LLVMIsConditional()

LLVMBool LLVMIsConditional

(

LLVMValueRef

Branch

)

Return if a branch is conditional.

This only works on llvm::BranchInst instructions.

See also

llvm::BranchInst::isConditional

LLVMSetCondition()

void LLVMSetCondition	(	LLVMValueRef	Branch,
		LLVMValueRef	Cond
	)

Set the condition of a branch instruction.

This only works on llvm::BranchInst instructions.

See also

llvm::BranchInst::setCondition

LLVMSetSuccessor()

void LLVMSetSuccessor	(	LLVMValueRef	Term,
		unsigned	i,
		LLVMBasicBlockRef	block
	)

Update the specified successor to point at the provided block.
