Daniel Marjamäki a9d56f2738 Tokenizer: simplify known variable value inside conditional block 2012-03-12 17:32:30 +01:00
PKEuS 6f164de609 Improved static string comparision check: Implemented #3214
Fixed false negative on argument count of fnprintf/snprintf when first variable argument is a string. (#3655)
Uncommented call of virtualDestructorError in getErrorMessages in checkclass.h
Refactorizations:
- Rearranged code in checkother.h to make ordering more consistent and to increase encapsulation of private data
- Replaced some single-token-patterns

Daniel Marjamäki 3f1ab5af9b charvar: dont write warning about char type array index when array is small and the full valid range is accessible with the char type. If there are out of bounds access then, it is not because the type of the variable. 2012-03-10 12:19:28 +01:00
August Sodora e0bee0e037 Fixed #3567 (False positives in boolean expressions) 2012-03-07 20:31:23 +01:00

PKEuS ef6e381d47 Improved bitwise on boolean check to make it working on more code patterns
Refactorizations in checkother.cpp:
- Make use of symboldabase instead of: indentation counters, manual detection of variable declarations
- Removed some indexing variables to reduce calls to tokAt and the numbers given to this function
- Use tok->nextArgument() to jump to a specific argument

PKEuS 1ef99e2f21 Improved checkautovariables:
- Added support for checking a few more code patterns
- Simplified code by using more information from the symboldatabase
- Moved redundant part of c_str-check to checkstl
Two fixes according to output of pvs studio in testsimplifytokens.cpp

PKEuS 1747813a8b Added check for invalid pointer casts (#1255)
Detect sign extension problems when variable is a reference (#3637)
Refactorizations:
- Tokenizer::getFiles returns a reference instead of a pointer, because its guaranteed that no nullpointer is returned
- Remove signed/unsigned in one step for "%type% signed|unsigned"
- Fixed recently introduced compiler warning in symboldatabase.cpp

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.
