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.

Use "constructors that are callable with a single argument" instead of
"single-argument constructors" when referring to constructors using default
arguments or parameter packs.

Summary:
Force braces on the else branch if they are being added to the if branch.
This ensures consistency in the transformed code.

Summary:
Anynoumous namespaces inject a using directive into the AST to import
the names into the containing namespace.
We should not have them in headers, but there is another warning for
that.

Followup to http://reviews.llvm.org/D8465, which would break a test in
clang-tidy. clang-tidy previously assumes that source locations of
defaulted/deleted members are (incorrectly) not including the '= ...' part.

Summary: The relevant style rule is going to be removed, thus the check is no longer needed in the Google module. Leaving the check in readability/ in case someone needs it.

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.

Summary:
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 {
} // anoynmous 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.

* Better error message when more than one of 'virtual', 'override' and 'final'
is present ("X is/are redundant since the function is already declared Y").
* 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
(http://llvm.org/PR22638).
