; This testcase comes from this C fragment:
;
; void test(unsigned Num, int *Array) {
;  unsigned i, j, k;
;
;  for (i = 0; i != Num; ++i)
;    for (j = 0; j != Num; ++j)
;      for (k = 0; k != Num; ++k)
;        printf("%d\n", i+k+j);    /* Reassociate to (i+j)+k */
;}
;
; In this case, we want to reassociate the specified expr so that i+j can be
; hoisted out of the inner most loop.
;
; RUN: llvm-upgrade < %s | llvm-as | opt -reassociate | llvm-dis | grep 115 | not grep 117
