-; RUN: opt -deadargelim -S < %s | FileCheck %s
-; PR14016
-
-; Built with clang (then manually running -mem2reg with opt) from the following source:
-; static void f1(int, ...) {
-; }
-;
-; void f2() {
-;   f1(1);
-; }
-
-; Test both varargs removal and removal of a traditional dead arg together, to
-; test both the basic functionality, and a particular wrinkle involving updating
-; the function->debug info mapping on update to ensure it's accurate when used
-; again for the next removal.
-
-; CHECK: define internal void @_ZL2f1iz({{.*}} !dbg [[SP:![0-9]+]]
-; CHECK: [[SP]] = distinct !DISubprogram(name: "f1"
-
-; Check that debug info metadata for subprograms stores pointers to
-; updated LLVM functions.
