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 |
