Edoardo Prezioso f3029ce6bb Fixed a bug in Tokenizer::simplifyKnownVariables. 
When we find constant variables, check if there's a usage of its reference in the code (for example: don't simplify 'f(&x)' to 'f(&100)').

Edoardo Prezioso 927d3e8ce2 Speed up the new CheckNullPointer checking. 
Related to commit 095824373a, using the new precomputed vector of functions, related to ticket #4266.

Robert Reif ffe657128f Fixed #4364 (Segfault in CheckStl::stlBoundries) 2012-11-20 06:12:14 +01:00
Edoardo Prezioso e0c10efdce Add a 'prepend' bool option to Token::InsertToken. 
If it's true, add a new token before this. Except when this is the first one in the list, because there's not a way to update the list.front (I noticed some Token functions can potentially delete the list.front(), I don't know which effects does it cause).

PKEuS e5ebb49312 Added support for sizeof(wchar_t). Improved <Windows.h> type testing for Win64 platform. 2012-11-11 16:16:17 +01:00
PKEuS 5555e055f1 Refactorized <Windows.h> type support: 
- Changed some more Win32 simplifications of wide-character/string types to use wchar_t
- Added support for LPWSTR
- Fixed test case to ensure that simplifications also work for Win32W
 2012-11-11 15:40:06 +01:00
PKEuS b15ff0c0e3 Fixed unit test failures caused by previous commit 2012-11-11 15:16:08 +01:00
PKEuS 4ea2df8671 Changed handling of type wchar_t: 
- Don't simplify wchar_t to unsigned short on Win32 platforms to ensure that checking of strings and nullpointer dereferences works.
- Added it as standard type
 2012-11-11 14:47:16 +01:00
PKEuS 17b720ef7d Refactorization: Removed unnecessary code. Variable::typeStartToken() and Variable::typeEndToken() never point to "const".

PKEuS 704f285c90 Refactorized CheckStl::pushback(): 
- insert(), reserve() and clear() also invalidate iterators
- Properly support return and throw statements: Bailout after semicolon
- "." is also bad usage of invalid iterator.
 2012-11-11 13:03:58 +01:00
Jose Roquette e8d3a4300d Fixed #4197 - False negative: invalidIterator2 not detected 2012-11-11 12:01:52 +01:00

PKEuS f75826c3e2 Added wstring to pattern where I forgot in bbe06c65c0 2012-11-09 20:25:50 +01:00
PKEuS 58fe7105f4 Remove C++11 keywords "override", "final" and "constexpr" 2012-11-09 19:53:10 +01:00
PKEuS ce961578c2 New checks (inconclusive): Suspicious calculation with sizeof() 
- Check for sizeof(ptr)/something: This indicates that programmer was trying to calculate array size, but sizeof(ptr) doesn't return the length of the memory area, but size of a pointer.
- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.
