| Add CCNO to indicate comparisons against zero that requires |
| Overflow flag to be unset. Sign bit test is used instead and |
| thus can be used to form "a&b>0" type of tests. |
| |
| Add CCGC to indicate comparisons against zero that allows |
| unspecified garbage in the Carry flag. This mode is used |
| by inc/dec instructions. |
| |
| Add CCGOC to indicate comparisons against zero that allows |
| unspecified garbage in the Carry and Overflow flag. This |
| mode is used to simulate comparisons of (a-b) and (a+b) |
| against zero using sub/cmp/add operations. |
| |
| Add CCA to indicate that only the Above flag is valid. |
| Add CCC to indicate that only the Carry flag is valid. |
| Add CCO to indicate that only the Overflow flag is valid. |
