; Regression test for PR47040, in which an assertion was improperly
; triggered during FastISel's address computation. The issue was that
; an `Address` set to be relative to FrameIndex zero was incorrectly
; considered to have an unset base. When the left hand side of an add
; set the Address to have a FrameIndex base of 0, the right side would
; not detect that the Address base had already been set and could try
; to set the Address to be relative to a register instead, triggering
; an assertion.
