// This tests the mnemonic spell checker.
// First check what happens when an instruction is omitted:
w1, w2, w3
// CHECK: error: unknown token in expression
// CHECK-NEXT: w1, w2, w3

// CHECK-NEXT: error: invalid operand
// CHECK-NEXT: w1, w2, w3

// We don't want to see a suggestion here; the edit distance is too large to
// give sensible suggestions:
addddddddd w1, w2, w3
// CHECK: error: unrecognized instruction mnemonic

// CHECK-NEXT: ^
addd w1, w2, w3
// CHECK: error: unrecognized instruction mnemonic, did you mean: add, addp, adds, addv, fadd, madd?
// CHECK-NEXT: addd w1, w2, w3

// Instructions 'addv' and 'addp' are only available when NEON is enabled, so we
