; LDS is allocated per-kernel. Module scope variables are gathered into a struct which is
; allocated at address zero, if used by the kernel. Kernel scope variables are gathered into
; a per-kernel struct and allocated immediately after the module scope.
; This test checks that the module and kernel scope variables are allocated in deterministic
; order without spurious alignment padding between the two

; External LDS is checked because it influences LDS padding in general and because it will
; not be moved into either module or kernel struct
