// Example 1: setting incoming values for a simple PHI node llvm::BasicBlock *entry = llvm::BasicBlock::Create(...); llvm::BasicBlock *ifTrue = llvm::BasicBlock::Create(...); llvm::BasicBlock *ifFalse = llvm::BasicBlock::Create(...); llvm::BasicBlock *merge = llvm::BasicBlock::Create(...); llvm::Value *cond = ...; // some condition llvm::PHINode *phi = llvm::PHINode::Create(...); phi->addIncoming(llvm::ConstantInt::getTrue(...), entry); phi->addIncoming(llvm::ConstantInt::getFalse(...), ifFalse); llvm::BranchInst *ifBranch = llvm::BranchInst::Create(ifTrue, ifFalse, cond, entry); llvm::BranchInst *mergeBranch = llvm::BranchInst::Create(merge, ifTrue); phi->addIncoming(...); // add merge value as incoming value for PHI nodeIn this example, we create a few basic blocks to represent a conditional branch instruction. We create a `PHINode` object and add two incoming values to it using `addIncoming`. Later, we add a third incoming value to the `PHINode` object after creating a `BranchInst` object and a merge block. The LLVM library provides a number of other similar examples in their documentation, including one that demonstrates the use of `PHINode setIncomingValue`. This method is part of the LLVM library, which is a collection of modular and reusable compiler and toolchain technologies.
