; DESCRIPTION:
|
|
;
|
|
; The kernel 'kern' makes a call to declared only function `foo`, hence `foo`
|
|
; is not considered as reachable callee, and is ignored. The function `goo`
|
|
; which uses LDS is not called from kernel 'kern', hence it is also ignored.
|
|
;
|
|
|
|
; Original LDS should exist.
