PKEuS d6261debdf Fixes false positives in test suite, adds unit test for void-simplification 2011-10-27 21:54:42 +03:00
Edoardo Prezioso 73f0e2c5b9 Fixed ticket #3227 (Improve tokenizer: labels are not handled correctly after a case or another label instruction)
Moved the labels simplification after combining the tokens and moved the case/default simplification inside the labels.
2011-10-19 14:20:09 +02:00
Thomas Jarosch a52b73f9f9 Fix #3208 (Simplify pointer to standard type, C only)
The symbol database is unavailable during token simplification
and &data[0] might return something completely different for C++.

Moved code_is_c() from checkOther to Tokenizer.

Daniel Marjamäki 371871b0b7 Tokenizer::removeMacrosInGlobalScope: Don't remove C/C++ keywords namespace/struct/etc. Ticket: #3193 2011-10-12 19:23:39 +02:00
Robert Reif ee04c1bfb7 fix #3194 (Parsing glitch causes false 'can be const' error for an 'if' statement) 2011-10-12 09:10:34 -04:00
Daniel Marjamäki 96beb94b21 Fixed #3183 (False positive: (error) syntax error) 2011-10-09 18:42:36 +02:00
Edoardo Prezioso 9270b84d64 More fixes to the label simplifier (related to ticket 3176):
1)Simplify the labels if there are combinations of the symbols '*','&','{' and '(' after a '%var% :' and before another '%var%';
2)but do not simplify the label if it's inside an unpreprocessed macro code.
2011-10-08 21:13:53 +02:00
Edoardo Prezioso 80df7ea839 Fixed ticket #3176 (cppcheck reports wrong unused variable)
Label simplification didn't take count of the '(' parenthesis or the '&' and '*' operators inside or outside the parenthesis after the colon.
2011-10-07 00:54:44 +02:00
Edoardo Prezioso fe4ce594ce Renamed the function 'removeRedundantCodeAfterReturn' with 'simplifyDeadCode'.
This is a preparation in order to add new features to this function (see the @todo in the tokenize header file, ticket #3113 and #3175 for details).
2011-10-06 22:40:39 +02:00
Edoardo Prezioso 8e90ad106c Fixed ticket #3148 (Analysis failed on "Modules/mathmodule.c")
Fix: Do not handle code when 'return' is inside a macro. This is valid also for 'switch' code inside a macro.
2011-10-05 19:33:46 +02:00
Edoardo Prezioso 3c370dcfdf Fixed #3146 "Analysis failed" error on softmagic.c:
-Fixed: the code didn't check the rightness of the switch syntax if it was inside another switch;
-Tweaked: removed the two bool variables, so now the conditions take count of indentation unsigned variables.

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.
