PKEuS eb2962792f Implemented support for move constructors:
- Changed behaviour of Token::function - is now also set for declarations
- Resolved TODO in testclass.cpp
- removed redundant code in Scope::findFunction - it is safe to call nextArgument() on functions without arguments

PKEuS 188096665c Implemented support for rvalue references (C++11):

Andrew C. Martin bd0d9b9639 fix misspellings & gcc v3.4.6 warnings
1.  fix typos / misspellings
 - Fix misspelling within comments, variable/function names, stdout messages
 - changes the name of an error code: ```stlBoundries``` changed to ```stlBoundaries```.  Alias old name (```stlBoundries```) to the new one.

2.  fix gcc v3.4.6 32bit & 64bit warnings

 - fixes gcc v3.4.6 warnings, except for those in tinyxml and "-Wmissing-declarations" makefile warnings
 - in Preprocessor::handleIncludes(), replace a ```vector <bool>``` with ```stack<bool>``` (see ```vector<bool>``` warning below).
   - this is the only ```vector<bool>``` in the codebase
 - ```vector <bool>``` is actually a case of template specialization, and is not recommended, according to the following links:

 - in the codebase before and after this change, testrunner SEGVs in a number of places on gcc v3.4.6, including ```Check::~Check()```, among others

Thomas Jarosch b1eec7c6b7 Small refactoring to compile more matches
*** Timing of the test suite ***
Four runs were used to calculate the average run time.

Before: ~1,103s
After: ~1,066s
Speed up: 3,35%

*** Timing of internal projects using STL ***
Before: ~8,301s
After: ~8,207s
Speed up: 1,13%

So the real world speed up is roughly 1%.

This little change gives another 6% speed improvement on my box.
(tested with the testsuite and checking the 'rpm' codebase)

The profiler showed we were spending quite some time in
Tokenizer::simplifyCallingConvention(). The multi match
pattern in there is "complex", at least for the on-the-fly parser.

- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)

- fix word misspellings (mostly comments, a few output lines)

  - Parenthesis => Parentheses (both variations were used in the codebase)

  - fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():

2013-01-09 17:06:04 +01:00
Thomas Jarosch 7dd07d8e77 Properly implement %op% for Token::multiCompare
Use tok->isOp() instead of doing it "manually".

This fixes false positives for the C++ template case since
the brackets in "template < something >" are not comparison operators.

Profiling showed using tok->isOp() is actually faster than before (-O2).
2013-01-09 17:05:53 +01:00
Thomas Jarosch 8b2adf1391 Change location of %op% operator in multicompare
When the %op% operator is the first element
of a multicompare, it properly executes Token::isOp().
Otherwise it uses it's "internal implementation".

Workaround inspired by Edoardo Prezioso.

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.

2012-11-11 15:40:06 +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

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.

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.

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.

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.

Edoardo Prezioso 24bf6f99e1 More simplifyRedundantParenthesis changes:

Edoardo Prezioso 93f1fed205 Tokenizer '?:' handling code refactorization:
