# This tests the mnemonic spell checker.
# First check what happens when an instruction is omitted:

# ALL: error: unknown instruction
# ALL-NEXT: $2, $1, $25
# ALL-NEXT: ^
# We don't want to see a suggestion here; the edit distance is too large to
# give sensible suggestions:
aaaaaaaaaaaaaaa $2, $1, $25
# ALL: error: unknown instruction
# ALL-NEXT: aaaaaaaaaaaaaaa $2, $1, $25
# ALL-NEXT: ^
# Check that we get one suggestion: 'addiuspi' is 1 edit away, i.e. an deletion.

# Check edit distance 1 and 2, just insertions:
