@ First check what happens when an instruction is omitted:

r1, r2, r3

@ CHECK-NEXT: r1, r2, r3

@ We don't want to see a suggestion here; the edit distance is too large to
|
|
@ give sensible suggestions:
|

aaaaaaaaaaaaaaa r1, r2, r3

@ CHECK: error: invalid instruction
|
|
@ CHECK-NEXT: aaaaaaaaaaaaaaa r1, r2, r3

@ Check that we get one suggestion: 'pushh' is 1 edit away, i.e. an deletion.
|
|
|
|
pushh r1, r2, r3
