...site is updated to call the new function, and add loads of any arguments that have been promoted. These loads may be removed by later optimizations. e.g. %a = alloca i32 %context = alloca {i32*} %field = getelementptr inbounds {i32*}* %context, i32 0, i32 0 store i32* %a, i32** %field call void @__captured_stmt_helper({i32*}* %context) define void @__captured_stmt_helper({i32*}* %context) { %field = getelementptr inbounds {i32*}* %context, i32 0, i32 0 %load.field = load i32** %field %a = load i32* %load.field ... } Becomes something like %a = alloca i32 %context = alloca {i32} %field = getelementptr...
