anuraggarg011 bf11248a09 Fixed #1620 (tokenizer: simplify well known math functions) 2012-09-03 18:51:15 +02:00
Edoardo Prezioso 0d26a79f2c Tokenizer::simplifyEmptyNamespaces: new function.
It removes from the token list, if found, the following tokens: 'namespace %var% { }'. It won't involve C code.

PKEuS f238f3fad5 Support sizeof in preprocessor directives
Applied "patch" provided by michaeln123 in #4071
2012-08-22 17:28:06 +02:00
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.
2012-08-12 03:01:24 -07:00
PKEuS 2ab33ef21b Added Pointer to enclosing scope to class Token (Only available when symboldatabase is created). 2012-08-11 11:47:11 -07:00
Daniel Marjamäki 0254344df5 Tokenizer::simplifyEnum: Reverted refactorings/optimisations as there were regressions (#3949, #3950, #4025) 2012-08-10 14:06:24 +02:00
PKEuS c8e40773f1 Fixed cppcheck messagesa about functions that can be const/static:
- Made Tokenizer::getErrorMessages static - Avoids creation of unnecessary instance of Tokenizer
- Changed Tokenizer::removeExceptionSpecifications to common style for simplification functions. In contrast to the comment, this function doesn't call itself recursivly - fixed comment.
- Made Tokenizer::IsScopeNoReturn static.

Daniel Marjamäki 6ad5fc8456 Refactoring Tokenizer::simplifyEnum. The enum handling is now somewhat faster since all enum values of a enum are simplified at the same time. 2012-07-06 15:43:50 +02:00

PKEuS 4b80e91145 Implemented support for building cppcheck lib into a dll
Updated VS9 solution
New VS10 solution that builds cppcheck into a dll used by cli and testrunner.
Functional changes and advantages of new solution:
- Share code between testrunner and cli; ability to share code with gui as well (not yet implemented)
- Files of /lib are no longer compiled twice (should improve build time on single core machines)
- Added configuration for building with PCRE support
- Executables are build into /bin (/bin/debug in debug mode) folder (Should no longer require rebuild when switching between debug and release)
- Completely x64 compatible (contains also x64-debug configuration now)

Removed ctor and dtor implementation from TemplateSimplifier: This class shouldn't be instanciated.

2012-03-19 18:45:47 +01:00
PKEuS 3af32b0da2 Refactorizations in tokenizer:
- getSourceFilePath returns a const reference now

Edoardo Prezioso 52620e6493 Tokenizer::simplifyDoWhileAddBraces:
1)rewrite fix for ticket #988 (just don't simplify inside macro parenthesis);
2)use a different organization of the code: start from last token and proceed backwards. This way 'simplifyDoWhileAddBracesHelper' can be called just once, hence the 'Helper' code can be improved and moved in the main function.
