PKEuS 2ac2674f67 Fixed #4000, added support for function prototypes to TemplateSimplifier::templateParameters() 2012-08-12 05:19:56 -07:00
PKEuS 35d94c26d5 Changed creation of SymbolDatabase. Database always created after Tokenizer::tokenize() and Tokenizer::simplifyTokenList() instead of on-demand creation by Tokenizer::getSymbolDatabase.
-> With Token::scope() it is possible to access the symboldatabase without having to call getSymbolDatabase(). The change increases safety because it is guaranteed that the database is available in all checks, even if the specific check doesn't call getSymbolDatabase
- Tokenizer::_symbolDatabase does no longer have to be mutable -> Increased const correctness

The change above required two additional changes:
- A bug causing a debug message was fixed in the symboldatabase that became visible in the test suite by the change above.
- Simplify expressions like "struct struct Foo" which might be result of typedef instanciation.

PKEuS 45bad7d1b2 Refactorized tokenizer:
- Don't run setVarId() twice, keep old varId's while/after simplifyTokenList
-> Modified two test cases in testmemleak.cpp. I consider this to be safe. Feel free to investigate this.
- Fixed two nullpointer issues shown by cppcheck
