PKEuS 42f418db54 - Improved nullpointer check: Fixed #1171
- Improved accuracy of function analysis in symboldatabase
- Code cleanups
2012-02-11 12:26:48 +01:00
Daniel Marjamäki bbb707c460 Fixed #3587 (Wrong tokenizer simplification - variable assigned by operator>>) 2012-02-07 08:05:50 +01:00
Daniel Marjamäki 47c7e346aa Uninitialized variables: Another fix for false positives when it's known that inner conditions are true 2012-02-06 19:26:28 +01:00
Daniel Marjamäki 05fc77c347 Revert "Uninit var: Added TODO test case"
The test case was not valid because the variable assignment is redundant and is therefore removed by the tokenizer.

This reverts commit 548a43fc49.

- Modify Cppcheck-class to catch InternalError instead of Token
- Run dmake to update Makefile
