| |
| <p><a name="index-bug-criteria-2058"></a> |
| If you are not sure whether you have found a bug, here are some guidelines: |
| |
| |
| <a name="index-fatal-signal-2059"></a> |
| <a name="index-assembler-crash-2060"></a> |
| <a name="index-crash-of-assembler-2061"></a> |
| <ul><li>If the assembler gets a fatal signal, for any input whatever, that is a |
| <samp><span class="command">as</span></samp> bug. Reliable assemblers never crash. |
| |
| <p><a name="index-error-on-valid-input-2062"></a><li>If <samp><span class="command">as</span></samp> produces an error message for valid input, that is a bug. |
| |
| <p><a name="index-invalid-input-2063"></a><li>If <samp><span class="command">as</span></samp> does not produce an error message for invalid input, that |
| is a bug. However, you should note that your idea of “invalid input” might |
| be our idea of “an extension” or “support for traditional practice”. |
| |
| <li>If you are an experienced user of assemblers, your suggestions for improvement |
| of <samp><span class="command">as</span></samp> are welcome in any case. |
| </ul> |
