XhmikosR 8ac9b8e7a9 remove duplicate ";" and fours dots 2013-04-09 17:49:09 +02:00
PKEuS 188096665c Implemented support for rvalue references (C++11):
- Split up && when it is part of an rvalue reference declaration
- Added support into symbol database
- Current implementation sets Variable::isReference() to true also for rvalue references - they can probably be treated like normal references in many checks.

Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList

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:

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2160.html
http://stackoverflow.com/q/670308

 - 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
   - fc42fc95 fixes this particular runtime issue for DJGPP & __sun

Andrew C. Martin 4a73c93750 Fix compiler warnings and comment/string typos
- fix g++ warning:

> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions

 - fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):

> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).

- 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():

```
-  "An unsigned variable will never alwayw be positive so it is either pointless or "
+  "An unsigned variable can't be negative so it is either pointless or "
```

Edoardo Prezioso 4c73c29cdd Revert partially the previous commit:
The two formulas are true iff 2n = 2 <=> n = 1.
2013-01-05 17:31:08 +01:00
Edoardo Prezioso 1c0c0471df Simplify some generalized math formulas:
Now the 'sin^2+cos^2=1' and the 'sinh^2-cosh^2=-1' code can handle, for example: sin^4+cos^4=1, sinh^10-cosh^10=-1.
Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.
2013-01-04 13:06:09 +01:00
Edoardo Prezioso 5485e6866f Fixed wrong tokenization of some math formulas:
