    llvm::Instruction* InsertBefore = nullptr)

Declared at: llvm/include/llvm/IR/Instructions.h:3702

Parameters

llvm::Value* Address

unsigned int NumDests

llvm::Instruction* InsertBefore = nullptr

¶static llvm::IndirectBrInst* Create(
    llvm::Value* Address,
    unsigned int NumDests,
    llvm::BasicBlock* InsertAtEnd)

Declared at: llvm/include/llvm/IR/Instructions.h:3707

Parameters

llvm::Value* Address

unsigned int NumDests

llvm::BasicBlock* InsertAtEnd

¶IndirectBrInst(llvm::Value* Address,
               unsigned int NumDests,
               llvm::Instruction* InsertBefore)

Description

Create a new indirectbr instruction, specifying an Address to jump to. The number of expected destinations can be specified here to make memory allocation more efficient. This constructor can also autoinsert before another instruction.

Declared at: llvm/include/llvm/IR/Instructions.h:3652

Parameters

llvm::Value* Address

unsigned int NumDests

llvm::Instruction* InsertBefore

¶IndirectBrInst(llvm::Value* Address,
               unsigned int NumDests,
               llvm::BasicBlock* InsertAtEnd)

Description

Create a new indirectbr instruction, specifying an Address to jump to. The number of expected destinations can be specified here to make memory allocation more efficient. This constructor also autoinserts at the end of the specified BasicBlock.

Declared at: llvm/include/llvm/IR/Instructions.h:3658

Parameters

llvm::Value* Address

unsigned int NumDests

llvm::BasicBlock* InsertAtEnd
