-; This example is intended to simulate this pass pipeline, which may not exist
-; in practice:
-; 1. DSE f from the original C source
-; 2. Inline escape
-; 3. mem2reg
-; This exercises the corner case of multiple llvm.dbg.addr intrinsics.
-
-; C source:
-;
-; void escape(int *px) { ++*px; }
-; extern int global;
-; void f(int x) {
-;   escape(&x);
-;   x = 1; // DSE should delete and insert dbg.value(i32 1)
-;   global = x;
-;   x = 2; // DSE should insert dbg.addr
-;   escape(&x);
-; }
