That's fair. Since this test isn't about load command dumping in general it's not a requirement of the test that we show there is exactly one load command (and even with the CHECK-NEXT, it doesn't enforce that, since nothing shows there are none after the one we actually check).

I don't have a strong opinion on the -NEXT suffix (adjusting the spacing would be good regardless). I gather that historically the output of FileCheck on failure is clearer for CHECK-NEXT versus plain CHECK, but I haven't looked into this myself and anyway, there have been substantial changes to the output since I heard that.
