Daniel Marjamäki 927a6e4794 Obsolete functions: removed 'ctime' warning. The function is obsolete but the message don't point out a good replacement nor where it's documented that this function is obsolete 2012-12-09 09:35:57 +01:00
PKEuS 410c0f98d9 Refactorized CheckObsoleteFunctions:
- Speedup checkobsoletefunctions by using symboldatabase and by not calling SymbolDatabase::findFunctionByToken() for each function call.
-> Benchmark (SQlite amalgamation):
    CheckObsoleteFunctions::runSimplifiedChecks(): 9s -> 0,016s (562%, 4% on entire runtime)
- Fixed false negative when passing function result as parameter

Edoardo Prezioso 0273c183a7 Run astyle and update the translation files.
I believe we need a hook script because else everytime we change a file we have to make a new commit to fix the discrepancies problems.

Edoardo Prezioso 45a16baaa0 Token: try to improve speed of multicompare macro. 2012-12-01 23:58:01 +01:00
Edoardo Prezioso f6c23fa1e7 runastyle and fix checkInternal messages. 2012-12-01 03:17:55 +01:00
Edoardo Prezioso 9ce6630b28 Add some unused private copy ctors and operator=.
In Token and in Check classes, GCC -Weffc++ reports that it's better to override the copy constructors and the assignment operator to avoid problems with copied objects which could have the same pointers, hence with double frees, when we delete one of these pointers in the copied and in the original object.

Edoardo Prezioso f42ab9871d Fix build breakage in recent commits. 2012-12-01 02:02:45 +01:00
Edoardo Prezioso 5101f3c029 Use the new pattern: '%comp%' where possible.
Change also the description comment of the Token::Match by adding the new pattern and the forgotten '%op%'.
2012-12-01 01:31:35 +01:00
Edoardo Prezioso aeb4531a58 Token::Match: add a new pattern: '%comp%'.
Token::Match returns true if the token is a comparison operator. It's equivalent to matching '<|<=|==|!=|>=|>' and the tests show that the new pattern speeds up the program execution. Added the new pattern in CheckInternal (and also reordered the %cmd% lists) and in TestToken.

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 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).

2012-11-11 15:40:06 +01:00
PKEuS 4ea2df8671 Changed handling of type wchar_t:

2012-11-11 14:47:16 +01:00
PKEuS 17b720ef7d Refactorization: Removed unnecessary code. Variable::typeStartToken() and Variable::typeEndToken() never point to "const".

2012-11-11 13:32:19 +01:00
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 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.
2012-11-09 18:08:20 +01:00
Edoardo Prezioso 119ab519a4 Support GNU extension of '?:' operator:
"x ? : y" is equivalent to "x ? x : y". I found a lot of code with this extension, probably we should warn a user to not use this.

2012-11-05 00:13:04 +01:00
Edoardo Prezioso 7293fcfa9b Remove redundant code in simplifyVarDecl:
TokenList::insertTokens adds the missing braces links when needed. The function does not add links to '<>', though, hence the TODO.
2012-11-05 00:12:22 +01:00
Edoardo Prezioso 4e25ffa948 Remove unexecuted branch in duplicateTypedef:
If the code is intended to be used, please revert + provide a valid testcase.
2012-11-04 23:03:14 +01:00
Edoardo Prezioso 333711ae4f Remove dead branch in simplifySizeof:
the code in that branch won't ever be executed because simplifySizeOf is called after arraySize, which adds the string length inside the '[]' parenthesis.
2012-11-04 22:41:38 +01:00
Edoardo Prezioso 24bf6f99e1 More simplifyRedundantParenthesis changes:
simplify also '( var . var . ... . var )' parenthesis.
2012-11-04 22:38:18 +01:00
Edoardo Prezioso b6b359d1c6 Tokenizer::simplifyRedundantParenthesis refactor:
Change useless 'while' to 'if' where possible; unify duplicate 'delete [| ]| var' handling code.
2012-11-04 20:51:40 +01:00
Edoardo Prezioso 93f1fed205 Tokenizer '?:' handling code refactorization:
move '=|,|(|[|{|}|;|case|return (%bool%) ?' code handling from simplifyConditionOperator in simplifyConstTernaryOp in order to use a more efficient code, thus to remove code duplication.

PKEuS a36e008967 Fixed #4314: Using CheckNullPointer::isPointerDeRef() here is overkill and doesn't work as intended, since this function is designed to return 'false' if it isn't sure. 2012-11-03 10:25:32 +01:00
Edoardo Prezioso c9e0089546 Change Tokenizer member function name.
From 'simplifyQuestionMark' to 'simplifyConstTernaryOp' (the older name was not clear). Adjusted the doxy comment.
