-; This test case was generated from the following source code:
-; 
-; long long foo(int *ptr, int cond) {
-;   long long result = 3;
-;   unsigned val = *ptr; // line 3
-;   switch (cond) {
-;   case 3:
-;     result = val;      // line 6
-;     break;
-;   case 4:
-;     result += 2;
-;   }
-; 
-;   return result + val;
-; };
-;
-; When CGP moves a zext Z of a load L to the block where L lives,  Z should not
-; retain its original debug location. Instead, Z should reuse the debug location
-; associated with L. Logically the zero extend will become part of the load; the
-; code generator will attempt to fuse the two instructions into a zextload.
