misc-redundant-expression
|
||
|
|
=========================
|
||
|
|
|
||
|
|
Detect redundant expressions which are typically errors due to copy-paste.
|
||
|
|
|
||
|
|
Depending on the operator expressions may be
|
||
|
|
|
||
|
|
- redundant,
|
||
|
|
|
||
|
|
- always ``true``,
|
||
|
|
|
||
|
|
- always ``false``,
|
||
|
|
|
||
|
|
- always a constant (zero or one).
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
.. code-block:: c++
|
||
|
|
|
||
|
|
((x+1) | (x+1)) // (x+1) is redundant
|
||
|
|
(p->x == p->x) // always true
|
||
|
|
(p->x < p->x) // always false
|
||
|
|
(speed - speed + 1 == 12) // speed - speed is always zero
