; RUN: llc < %s

; This caused a problem because the argument of a call was defined by
; the return value of another call that appears later in the code.
; When processing the first call, the second call has not yet been processed
; so no LiveRange has been created for its return value.
; 
; llc dies in UltraSparcRegInfo::suggestRegs4CallArgs() with:
;     ERROR: In call instr, no LR for arg: 0x1009e0740
