This check will try to enforce coding guidelines on the identifiers naming.
It supports lower_case, UPPER_CASE, camelBack and CamelCase casing and
tries to convert from one to another if a mismatch is detected.
It also supports a fixed prefix and suffix that will be prepended or appended
to the identifiers, regardless of the casing.
Many configuration options are available, in order to be able to create
different rules for different kind of identifier. In general, the
rules are falling back to a more generic rule if the specific case is not
configured.

llvm-svn: 245429
Summary:
The existing check converts the code pattern below:
void f()
{
}
to:
void f()
override {
}
which is fairly sub-optimal. This patch fixes this by inserting the
override keyword on the same line as the function declaration if
possible, so that we instead get:
void f() override
{
}
We do this by looking for the last token before the start of the body
and inserting the override keyword at the end of its location. Note
that we handle const, volatile and ref-qualifiers correctly.
Test Plan: Includes an automated test.

As there don't seem to be a good way of formulating a matcher that

Enhance clang-tidy readability-simplify-boolean-expr to handle 'if (e) return

This changeset extends the simplify boolean expression check in clang-tidy to
simplify if (e) return true; return false; to return e; (note the lack of an
else clause on the if statement.) By default, chained conditional assignment is
left unchanged, unless a configuration parameter is set to non-zero to override
this behavior.

static_cast<bool>(expr) when expr is not of type bool.

We are porting some of the checkers at a company we developed to the Clang Tidy
infrastructure. We would like to open source the checkers that may be useful
for the community as well. This patch is the first checker that is being ported
to Clang Tidy. We also added fix-it hints, and applied them to LLVM:
http://reviews.llvm.org/D6924
The code compiled and the unit tests are passed after the fixits was applied.
The documentation of the checker:
/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.
It also uses some custom ASTMatchers. In case you find them useful I can submit
them as separate patches to clang. I will apply your suggestions to this patch.
