This reverts commit 1fa1ddccba.
2012-03-20 19:00:16 +01:00
Daniel Marjamäki 1fa1ddccba Fixed #3648 (Internal error: Token::Match called with varid 0) 2012-03-20 18:58:27 +01:00
PKEuS cb2a754983 Implemented support for C++11 right angle brackets (>>)
Implemented support for linkage between < and > (Information: It is possible that under certain circumstances comparision operators are linked, since its sometimes difficult to separate between them.)
2012-03-19 18:45:47 +01:00
PKEuS 3af32b0da2 Refactorizations in tokenizer:
- getSourceFilePath returns a const reference now
- Replaced some simple patterns by string comparisions/direct function calls
- Replaced a few indendation counters by easier code
- Replaced one offset variable by token pointer to avoid subsequent calls to tokAt with the same number
2012-03-17 11:48:40 +01:00
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
2012-02-26 11:56:32 +01:00
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

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.
