Raw Blame History

; This testcase, obviously distilled from a large program (bzip2 from
; Specint2000) caused instcombine to fail because it got the same instruction
; on it's worklist more than once (which is ok), but then deleted the
; instruction. Since the inst stayed on the worklist, as soon as it came back
; up to be processed, bad things happened, and opt asserted.
;
; RUN: llvm-as < %s | opt -instcombine
;
; END.
