| # This tests the mnemonic spell checker. |
| |
| # First check what happens when an instruction is omitted: |
| |
| %r1, %r2, %r3 |
| |
| # CHECK: error: unexpected token at start of statement |
| # CHECK-NEXT: %r1, %r2, %r3 |
| # CHECK-NEXT: ^ |
| |
| # 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-NEXT: ^ |
| |
| # Check that we get one suggestion: 'vmaxfpg' is 1 edit away, i.e. an deletion. |
| |
| vmaxfpg %r1, %r2 |
| |
| # CHECK: error: invalid instruction, did you mean: vmaxfp? |
| # CHECK-NEXT: vmaxfpg %r1, %r2 |
| # CHECK-NEXT: ^ |
| |
| # Check edit distance 1 and 2, just insertions: |
| |
| xsnmsubad %r1, %r2 |
| |
| # CHECK: error: invalid instruction, did you mean: xsmsubadp, xsnmsubadp? |
| # CHECK-NEXT: xsnmsubad %r1, %r2 |
| # CHECK-NEXT: ^ |
| |
| # Check an instruction that is 2 edits away, and also has a lot of candidates: |
| |
| adXd %r1, %r2, %r3 |
| |
| # CHECK: error: invalid instruction, did you mean: add, addc, adde, addi, fadd? |
| # CHECK-NEXT: adXd %r1, %r2, %r3 |
| # CHECK-NEXT: ^ |
