Pavel Roschin 19a8cfd960 Library: add new "define" tag
This tag will allow to add some preprocessor defs into library.
It would be useful to provide more information about libraries
implementation details. As example GLib's library include tag
was added that helps to detect more memory leaks.

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.
2012-08-12 03:01:24 -07:00
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

Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking.
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
