LLVM Basic Block Representation.

const Function * getParent() const

Return the enclosing method, or null if none.

static BasicBlock * Create(LLVMContext &Context, const Twine &Name="", Function *Parent=nullptr, BasicBlock *InsertBefore=nullptr)

Creates a new BasicBlock.

LLVM_ABI BasicBlock * splitBasicBlock(iterator I, const Twine &BBName="", bool Before=false)

Split the basic block into two basic blocks at the specified instruction.

LLVM_ABI LLVMContext & getContext() const

Get the context in which this basic block lives.

const Instruction * getTerminator() const LLVM_READONLY

Returns the terminator instruction if the block is well formed or null if the block is not well forme...

Value * getArgOperand(unsigned i) const

LLVM_ABI Intrinsic::ID getIntrinsicID() const

Returns the intrinsic ID of the intrinsic called or Intrinsic::not_intrinsic if the called function i...

This class represents a function call, abstracting a target machine's calling convention.

Value * CreateExtractElement(Value *Vec, Value *Idx, const Twine &Name="")

PHINode * CreatePHI(Type *Ty, unsigned NumReservedValues, const Twine &Name="")

BranchInst * CreateCondBr(Value *Cond, BasicBlock *True, BasicBlock *False, MDNode *BranchWeights=nullptr, MDNode *Unpredictable=nullptr)

Create a conditional 'br Cond, TrueDest, FalseDest' instruction.

Value * CreateAdd(Value *LHS, Value *RHS, const Twine &Name="", bool HasNUW=false, bool HasNSW=false)

LLVM_ABI Value * CreateElementCount(Type *Ty, ElementCount EC)

Create an expression which evaluates to the number of elements in EC at runtime.

This provides a uniform API for creating instructions and inserting them into a basic block: either a...

LLVM_ABI InstListType::iterator eraseFromParent()

This method unlinks 'this' from the containing basic block and deletes it.

LLVM_ABI void setSuccessor(unsigned Idx, BasicBlock *BB)

Update the specified successor to point at the provided block.

static LLVM_ABI IntegerType * get(LLVMContext &C, unsigned NumBits)

This static method is the primary way of constructing an IntegerType.

This is an important class for using LLVM in a threaded context.

A Module instance is used to store all the information related to an LLVM module.

void addIncoming(Value *V, BasicBlock *BB)

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

The instances of the Type class are immutable: once they are created, they are never changed.

LLVM Value Representation.

Type * getType() const

All values are typed, get the type of this value.

LLVM_ABI void replaceAllUsesWith(Value *V)

Change all uses of this to point to a new Value.
