|
- * * Other than that, if you don't know the likelihood of a test

|
- * succeeding from empirical or other `hard' evidence, don't
|
|
|
- * make predictions.
|
|
|
- *
|
|
|
- * * These are meant to be used in places that are run `a lot'.
|
|
|
- * It is wasteful to make predictions in code that is run
|
|
|
- * seldomly (e.g. at subsystem initialization time) as the
|
|
|
- * basic block reordering that this affects can often generate
