An example of this happening today with C++ structured bindings is here: https://godbolt.org/z/rn3os13M7 . Specifically, the i64 return value from "f", a squashed-together pair of i32s, is decomposed into two `#dbg_value`s corresponding to the two variables that the structured-binding assigns to. Each `#dbg_value` refers to different IR Values, which seems similar to what's desired here. The major difference is that structured bindings have independent source variables contained within one alloca; wheras the situation here is one source variable being split into fragments. https://github.com/llvm/llvm-project/pull/135230 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
