|
|
We test these features:
|
|
|
|
- Multiple commands for the same (double-colon) target
|
|
- Different prerequisites for targets: only out-of-date
|
|
ones are rebuilt.
|
|
- Double-colon targets that aren't the goal target.
|
|
|
|
Then we do the same thing for parallel builds: double-colon
|
|
targets should always be built serially.";
