Richard Quirk 7f88b66842 Fix namespaced types for auto_ptr new[] errors
This fixes false negatives for code such as:

    std::auto_ptr<foo::bar> p(new foo::bar[10]);

The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.

Richard Quirk 68202d8ffb Extra check for auto_ptr new[]
This fixes cases like this:

   auto_ptr<foo> bar(new foo[10]);

which previously did not work correctly.

Daniel Marjamäki d23c58d387 enable: break out 'performance' and 'portability' from the 'style' id. Ticket: #3074 2011-09-03 15:30:30 +02:00
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.

CURRENT (as-is):    Documenting how cppcheck behaves now.

This removes the need for an ASSERT_EQUALS but enforces the check for every TODO_ASSERT_EQUALS.
