; Setting new access functions where the base pointer of the array that is newly
|
||
|
|
; accessed is only loaded within the scop itself caused incorrect code to be
|
||
|
|
; generated when invariant load hoisting is disabled. Since r282893 we assert
|
||
|
|
; in such situations. This test case was added to demonstrate what needs to be
|
||
|
|
; resolved to support such access functions.
