; 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.
