¶llvm::Instruction* promoteCallWithIfThenElse(
    llvm::CallSite CS,
    llvm::Function* Callee,
    llvm::MDNode* BranchWeights = nullptr)

Description

Promote the given indirect call site to conditionally call \p Callee. This function creates an if-then-else structure at the location of the call site. The original call site is moved into the "else" block. A clone of the indirect call site is promoted, placed in the "then" block, and returned. If\p BranchWeights is non-null, it will be used to set !prof metadata on the new conditional branch.

llvm::Function* Callee

llvm::MDNode* BranchWeights = nullptr
