; 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.
