This directory needs to be reorganized and some of the tests need changes to make them executable. Also comments would help... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2865 91177308-0d34-0410-b5e6-96231b3b80d8

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