4;; Test the sequence:
5;; cast -> setle 0, %cast -> br %cond
6;; This sequence should cause the cast value to be forwarded twice,
7;; i.e., cast is forwarded to the setle and teh setle is forwarded
8;; to the branch.
9;; register argument of the "branch-on-register" instruction, i.e.,
10;;
11;; This produces the bogus output instruction:
12;; brlez <NULL VALUE>, .L_SumArray_bb3.
13;; This came from %bb1 of sumarrray.ll generated from sumarray.c.
