PKEuS fd7c90f68d Forgot to commit a file in eb2962792f. 2013-04-04 10:57:35 -07:00
PKEuS eb2962792f Implemented support for move constructors:
- Changed behaviour of Token::function - is now also set for declarations
- Resolved TODO in testclass.cpp
- removed redundant code in Scope::findFunction - it is safe to call nextArgument() on functions without arguments
- Use Token::function in checkother.cpp
2013-04-04 10:53:55 -07:00
PKEuS 188096665c Implemented support for rvalue references (C++11):
- Split up && when it is part of an rvalue reference declaration
- Added support into symbol database
- Current implementation sets Variable::isReference() to true also for rvalue references - they can probably be treated like normal references in many checks.

Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList
