// Create a new basic block BasicBlock* bb = BasicBlock::Create(Context, "mybb", function); // Create a branch instruction to the next basic block BranchInst* br = BranchInst::Create(nextBB, bb); // Set the terminator instruction for the basic block bb->getTerminator() = br;In this example, we create a new basic block "mybb" and a new branch instruction that jumps to the next basic block. We then set the current basic block's terminator instruction to the branch instruction using `getTerminator()`. TerminatorInst is part of the LLVM core library and is not a standalone package. It can be accessed by including the appropriate header files and linking against the LLVM libraries.
