The misc-static-assert check will not warn on the followings:
assert(NULL == "shouldn't warn");
assert(__null == "shouldn't warn");
Where NULL is a macro defined as __null.

The number of strings is so small that performance doesn't matter and adding
the thread safe static initialization and destruction overhead is just not
worth it. No functional change intended.

This check looks for comparisons between boolean expressions and boolean
constants and simplifies them to just use the appropriate boolean expression
directly.
if (b == true) becomes if (b)
if (b == false) becomes if (!b)
if (b && true) becomes if (b)
if (b && false) becomes if (false)
if (b || true) becomes if (true)
if (b || false) becomes if (b)
e ? true : false becomes e
e ? false : true becomes !e
if (true) t(); else f(); becomes t();
if (false) t(); else f(); becomes f();
if (e) return true; else return false; becomes return (e);
if (e) return false; else return true; becomes return !(e);
if (e) b = true; else b = false; becomes b = e;
if (e) b = false; else b = true; becomes b = !(e);

Summary:
Do not warn on .reset(.release()) expressions if the deleters are not
compatible.
Using plain assignment will probably not work.

The misc-static-assert check will not warn on assert(false), assert(False),
assert(FALSE); where false / False / FALSE are macros expanding to the false or
0 literals.
Also added corresponding test cases.

Replace unrecognized namespace ending comments. This will help in particular when a namespace ending comment is mistyped or doesn't fit the regexp for other reason, e.g.:
namespace a {
namespace b {
namespace {

} // b
} // namesapce a

This patch contains two assert related checkers. These checkers are the part of
those that is being open sourced by Ericsson
(http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-December/040520.html).
The checkers:
AssertSideEffect:
/// \brief Finds \c assert() with side effect.
///
/// The conition of \c assert() is evaluated only in debug builds so a condition
/// with side effect can cause different behaviour in debug / relesase builds.
StaticAssert:
/// \brief Replaces \c assert() with \c static_assert() if the condition is
/// evaluatable at compile time.
///
/// The condition of \c static_assert() is evaluated at compile time which is
/// safer and more efficient.

* Convert the messages to the style used in Clang diagnostics: lower case
initial letter, no trailing period.
* Don't run the check for files compiled in pre-C++11 mode

Algorithms like remove() does not actually remove any element from the
container but returns an iterator to the first redundant element at the end
of the container. These redundant elements must be removed using the
erase() method. This check warns when not all of the elements will be
removed due to using an inappropriate overload.

This makes clang-tidy merge the default set of checks with the one
provided in the configuration file instead of just using the checks from the
config file. This adds a way to modify the default set of checks while the
previous behavior required to always define the set of checks completely.
