* Test coverage
|
| 31 |
|
|
*
|
| 32 |
|
|
* The l.add, l.addc, l.addi and l.addic instructions should set the carry and
|
| 33 |
|
|
* overflow flags.
|
| 34 |
|
|
*
|
| 35 |
|
|
* In addition the l.addc and l.addic instructions should add in the carry
|
| 36 |
|
|
* bit.
|
| 37 |
|
|
*
|
| 38 |
|
|
* Problems in this area were reported in Bugs 1771 and 1776. Having fixed the
|
| 39 |
|
|
* problem, this is (in good software engineering style), a regression test
|
| 40 |
|
|
* to go with the fix.
|
| 41 |
|
|
*
|
| 42 |
|
|
* This is not a comprehensive test of any instruction (yet).
|
| 43 |
|
|
*
|
| 44 |
|
|
* Of course what is really needed is a comprehensive instruction test...
