Daniel Marjamäki 7c47283e6d Fix testrunner 2018-12-04 17:17:07 +01:00
IOBYTE 2275f05f65 Fixed #8833 (false negative: No 'return' statement in non-void function causes undefined behavior.) (#1463) 2018-11-05 06:55:30 +01:00
IOBYTE 0a30768b59 Fixed #8693 (Template specialization: Constructor detected as normal … (#1418)
* Fixed #8693 (Template specialization: Constructor detected as normal function (functionStatic error))

Refactor template simplifier to remove the existing full specialization
function expandSpecialized and allow full specializations to use the
existing function expandTemplate.  The function expandTemplate was
modified to either expand the template like it originally did by copying
it or to modify the template in place.  Both instantiated and
uninstantiated full specializations are modified in place.  This also
fixes #8692 and probably other related tickets as well.

The function simplifyTemplates now tries twice to simplify templates so
more templates can be simplified.  We should try as many times as
necessary to find all possible templates.  We can't do that now because
uninstantiated templates are left unchanged.  It is relatively straight
forward to have the new code also expand in place uninstantiated
templates with their symbolic types but namespaces are not handled
properly (ticket #8671) and it would introduce regressions.

* Fix travis warnings.

Daniel Marjamäki a31db92918 Fixed #8669 (operator>> causes wrong style message) 2018-10-03 13:00:11 +02:00
rikardfalkeborn 5e120b567c isVariableDeclaration: Handle pointer to const pointer (#1395)
isVariableDeclaration did not handle pointer to const pointer, or
pointer to volatile pointer. This resulted in FPs in examples like the
following:

    class Fred {
        public:
        const char *const *data;
        const char *const *getData() { return data; };
    }

where cppcheck would say getData could be static, since it didn't
recognize const char *const *data as a variable declaration.

Adapt code to Function::eMoveConstructor
introduced in commit eb2962792f
2013-04-10 21:57:22 +02:00
PKEuS eb2962792f Implemented support for move constructors:
- Changed behaviour of Token::function - is now also set for declarations

- removed redundant code in Scope::findFunction - it is safe to call nextArgument() on functions without arguments
- Use Token::function in checkother.cpp
