Bugfix: Update Token type when varId is set

PKEuS 76fbcce13f Restored (intentional) content of screwed up commits 1bcdf4ce3d and 674f7980d519712ff16d8f874dfe55a84deb4b5b:
- New check (Inconclusive): Array filled incompletely with memset/memcpy/memmove
-- This check only warns if the number of elements is given as size in bytes to memset, memcpy or memmove and if the size of an element is larger than 1 Byte. It does not warn for random numbers

- New check: Detect ineffective statements like '*foo++;' (Should be: '(*foo)++;')

Sorry for the inconveniences.

PKEuS 6364f43b7a Fixed compiler error introduced recently. 2012-08-22 16:41:11 +02:00
Arpit Chaudhary 7c8da17c44 Added check for detecting if a variable or number is shifted by negative right operand. Statements like:
int i = -1;
 a << i;

 would result in an error message stating undefined behavior.

PKEuS a243983242 Refactorized type handling in CheckIO and CheckOther:
- Added several types (std::) to isComplexType
- Types in namespace std:: are considered to have no side-effects (solved one TODO)

PKEuS a15e307df0 Replaced two more indentation counters 2012-08-12 04:12:17 -07:00
PKEuS c8773b891d Refactorization: Make use of Token::scope() replacing certain indentation counters 2012-08-12 03:13:07 -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

Ran Astyle on teststl.cpp
