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 "
```

- Replaced two indendation counters and one variable storage by symboldatabase functions
- Removed zero-element at end of two static arrays
- More accurate algorithm for finding a parameter by varid
- Replaced some simple tokens by direct string comparision
- Made some functions in checkmemoryleak.h private to improve encapsulation

Daniel Marjamäki 45759f6f7d CheckMemoryLeak: report debug warning when variable id is 0. Ticket #3527 2012-03-14 18:54:34 +01:00
Daniel Marjamäki 9df6088ddd Revert "really fix #3527 (Internal error. Token::Match called with varid 0. Please report this to Cppcheck developers)"
This reverts commit a37031944e.

I don't want this hard coding of macro names. Feel free to come with a more generic solution if you want.

PKEuS 167a7e3e51 Various code cleanups 2011-12-08 21:28:34 +01:00
Edoardo Prezioso 4de5d87078 1)Remove newly copy of 'eraseTokens' and replace every occurrence with 'deleteNext' with right parameter.
2)General improvements to code.
2011-12-08 01:44:18 +01:00
Edoardo Prezioso 612b3c59ca 1)Implement another declaration of 'Token::eraseTokens' with parameters: the starting token and the number of times needed to call 'deleteNext'.
2)Use the overloaded 'eraseTokens' where needed instead of using consecutively 'deleteNext'.
3)Tokenizer: general optimizations about the deletion of some tokens.
4)Run astyle.

Edoardo Prezioso 11dd3c09ce Change every 'tokAt(1)->' to 'next()->' because 'tokAt(1) == 0' is equivalent to 'next() == 0', hence the equivalent cppcheck crash. 2011-11-20 15:09:57 +01:00

Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking.
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
