; Check to make sure the tail-call return at the end doesn't use a
|
|
; callee-saved register. Register hinting from t2LDRDri was getting this
|
|
; wrong. The intervening call will force allocation to try a high register
|
|
; first, so the hint will attempt to fire, but must be rejected due to
|
|
; not being in the allocation order for the tcGPR register class.
|
|
; The machine instruction verifier will make sure that all actually worked
|
|
; out the way it's supposed to.
