3 # This tests the mnemonic spell checker.
5 # First check what happens when an instruction is omitted:
7 v2, v4, v6
9 # CHECK: error: invalid instruction
10 # CHECK-NEXT:{{^}}v2, v4, v6
11 # CHECK-NEXT:{{^}}^
13 # We don't want to see a suggestion here; the edit distance is too large to
14 # give sensible suggestions:
16 aaaaaaaaaaaaaaa v1, v2, v3
18 # CHECK: error: invalid instruction
19 # CHECK-NEXT:{{^}}aaaaaaaaaaaaaaa v1, v2, v3
20 # CHECK-NEXT:{{^}}^
22 # Check that we get one suggestion: 'dsc_write_src2_b64' is 1 edit away, i.e. an deletion.
24 dsc_write_src2_b64 v1, v2, v3
26 # CHECK: error: invalid instruction, did you mean: ds_write_src2_b64?
27 # CHECK-NEXT:{{^}}dsc_write_src2_b64 v1, v2, v3
28 # CHECK-NEXT:{{^}}^
30 # Check edit distance 1 and 2, just insertions:
32 s_mov_b v1, v2

35 # CHECK-NEXT:{{^}}s_mov_b v1, v2
36 # CHECK-NEXT:{{^}}^
38 # Check an instruction that is 2 edits away, and also has a lot of candidates:
40 s_load_dwordx v1, v2, v3
42 # CHECK: error: invalid instruction, did you mean: s_load_dword, s_load_dwordx16, s_load_dwordx2, s_load_dwordx4, s_load_dwordx8?
43 # CHECK-NEXT:{{^}}s_load_dwordx v1, v2, v3
