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

 - 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

Also, the arguments can be also multitokens, so that it's possible to simplify, for example: 'sin^2(k())+cos^2(k())=1'.

PKEuS c9f5117cf5 Fixed #3407 (False positive: (inconclusive) Found duplicate branches for if and else. (inline assembler)) 2011-12-13 21:42:38 +01:00
Edoardo Prezioso 79b82f115f Tokenizer: some changes to line numbers of some tokens:
simplifyAsm: change line number of newly added 'asm ( )' in order to be the same as next ';'.
simplifyIfAddBraces: Change line number of newly added '}' in order to be the same as next 'else', except for '{ ; } else'.

Edoardo Prezioso 6506b2c016 Oops. Fix testrunner fail. 2011-12-11 20:36:56 +01:00
Edoardo Prezioso 3c098839d1 simplifyIfAddBraces: Remove restriction for jumping opening parenthesis '(' as a fix to #2873, because even without this the original test case doesn't crash anymore. Add more jumping patterns.
simplifyFunctionParameters: Add more jumping patterns and an observation related to error message for equal parameter names, help needed.
Fix grammar mistake in comment.

Edoardo Prezioso 27801b35eb Other improvements to tokenizer code.
Handle SQL code better, even when there's no ';' after 'EXEC SQL'.
simplifyVarDecl: Check with 'Token::Match' once when you have to check a pattern inside which there should be a number or a variable. Use '%any%' and after that check if that string is a number or a variable name later.
simplifyGoto: process also anonymous structs and unions which should have 'indentspecial' incremented, skip code like 'var = { ... }'.

Edoardo Prezioso 5134964026 Fix code in commit 5f522fb841 and reapply it again. 2011-12-10 23:49:56 +01:00
Daniel Marjamäki 04159b81b8 reverted 5f522fb841, to avoid hang in TestBufferOverrun::arrayInfo 2011-12-10 20:51:36 +01:00
Edoardo Prezioso 5f522fb841 Tokenizer: improve code and remove redundant checks.
In particular: improve 'double sharp' concatenation by handling also code which begins without the [{};]. Do the same with C# code. Also, in the labels simplification function, skip also '{}' when the open bracket is after a '='.
