* 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

* expression to evaluate to false.
|
||||
*
|
||||
* A few notes about usage:
|
||||
*
|
||||
* * Generally, __predict_false() error condition checks (unless
|
||||
* you have some _strong_ reason to do otherwise, in which case
|
||||
* document it), and/or __predict_true() `no-error' condition
|
||||
* checks, assuming you want to optimize for the no-error case.
|
||||
*
|
||||
* * 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
|
||||
* larger code.
