; This test is to verify that PGO runtime library calls get created with the
; appropriate operand bundle funclet information when a memory intrinsic
; being value profiled is called within an exception handler.

; Test case based on this source:
;  #include <memory.h>
;
;  extern void may_throw(int);
;
;  #define MSG "0123456789012345\0"
;  unsigned len = 16;
;  char msg[200];
;
;  void run(int count) {
;    try {
;      may_throw(count);
;    }
;    catch (...) {
;      memcpy(msg, MSG, len);
;      throw;
;    }
;  }
