3d5781743c ValueFlow: Restore handling of not 2015-07-16 21:17:44 +02:00
Daniel Marjamäki
15a8e4d2df Temporarily revert "Fixed (condition is always true (variable is assigned constant value and then used in condition))" 
This reverts commit a3fbad50cb2d21d88f51b105a73ef89773dfda6b.

The ValueFlow must be updated before this can be re-added.
