we're loading the first array element and doing an explicit null check after that..
0xffffffff73902628: ld [%g1 + 16], %l7
0xffffffff7390262c: add %l2, %l3, %l6
0xffffffff73902630: cxbe %g1, %g0, 0xffffffff73902688 ! 0xffffffff73902688
0xffffffff73902634: nop

Maybe related to arraycopy as macro node change
