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

PKEuS 9431fb1b7e Improved STL checks: 
- Added performance checking for .c_str() for return values and function parameters (#1079)
- Added more containers (basic_string, C++11 containers) and more functions to checking (.at, .resize, .reserve, ...)
- Make use of symboldatabase in missingComparision check
 2012-02-25 12:43:27 +01:00
PKEuS 9a5f66030c Improved unused private function check: 
- Fixed #3628
- Added support for friend
Improved symbol database:
- friend scopes are now set
- Added findScopeByName function
Refactorizations:
- Removed some unnecessary "virtual" keywords
- Removed unnecessary _filename member variable, pass it as argument instead
- Made CppCheck::replaceAll static, since it is independant from a specific CppCheck instance, Pass string to be modified by reference

Daniel Marjamäki 9df6088ddd Revert "really fix #3527 (Internal error. Token::Match called with varid 0. Please report this to Cppcheck developers)" 
This reverts commit a37031944e.

I don't want this hard coding of macro names. Feel free to come with a more generic solution if you want.

Edoardo Prezioso 52620e6493 Tokenizer::simplifyDoWhileAddBraces: 
1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.
