Daniel Marjamäki b8d233f1a2 false poitive - invalid iterator after break 2012-04-09 07:19:39 +02:00
PKEuS d6cfbc6483 Improved checks in CheckStl: 
- Generalized check for inefficient emptiness check to detect !%var%.size() calls also outside of if and while; detect it also for %var%.size() when linked with && or ||.
Refactorizations in CheckStl:
- Removed an indendation counter and an offset variable
- Reduced distance given to tokAt calls in CheckStl::redundantCondition
- Rearranged code in CheckStl::missingComparison to use more efficient comparision of varIds instead of variable names. Use varId in pattern instead of variable name.
