This diff requires http://reviews.llvm.org/D13079 to be applied first. I wasn't sure about how to make patch series in Phabricator, and I wanted to keep the two separate for clarity.
It looks like that most cases can be supported with this patch. I'm not totally sure about the actual coverage though. I think that the matchers are very generic, but I'm still not totally fluent with the AST.

This fixes https://llvm.org/bugs/show_bug.cgi?id=22196 .
Also add a non-trivially copyable type to fix some tests that were meant to be about using const-refs, but were changed in r248438.

Summary:
compile_commands.json is usually generated in the build directory.
Projects like LLVM/Clang enforce out-of-source builds.
This option allow allow such projects to work out of the box, without
moving the compilation database manually.
The naming of the option is similar to the one use by other tools:
clang-{check,modernize,query,rename,tidy} -p=<build_path> <...>

This is to level the ground a little bit, in preparation for the changes in http://reviews.llvm.org/D13081.
Code factorization replaces all insertions to NamingCheckFailures map with a unique addUsage function that does the job.
There is also no more difference between the declaration and the references to a given identifier, both cases are treated as ranges in the Usage vector. There is also a check to avoid duplicated ranges to be inserted, which sometimes triggered erroneous replacements.
References can now also be added before the declaration of the identifier is actually found; this looks to be the case for example when a templated class uses its parameters to specialize its templated base class.

Previously, we would rewrite:
void f(const vector<int> &v) {
for (size_t i = 0; i < v.size(); ++i) {
to
for (const auto &elem : v) {
Now we rewrite it to:
for (auto elem : v) {
(and similarly for iterator based loops).
llvm-svn: 248438
Previously we would use a non-const loop variable in the range-based
loop for:
void f(const std::vector<int> &v) {
for (size_t i = 0; i < v.size(); ++i) {
Now we use const auto&.
Note that we'll also want to use a copy at least for simple types.

Scripts are installed in same location as clang-fromat ones, so I think will be good idea to not create dedicated directory.
I checked this patch on my own build on RHEL 6.
Please check it in if it's OK, because I don't have SVN write access.
I think will be good idea to backport this patch to 3.7 release branch.
Probably same should be done for configure build.

Summary:
1. Avoid converting loops that iterate over the size of a container and don't use its elements, as this would result in an unused-result warning.
2. Never capture the elements by value on lambdas, thus avoiding doing unnecessary copies and errors with non-copyable types.
3. The 'const auto &' instead of 'auto &' substitution on const containers now works on arrays and pseudoarrays as well.
4. The error about multiple replacements in the same macro call is now documented in the tests (not solved though).
5. Due to [1], I had to add a dummy usage of the range element (like "(void) *It;" or similars) on the tests that had empty loops.
6. I removed the braces from the CHECK comments. I think that there is no need for them, and they confuse vim.

This is first of series of patches, porting code from my project colobot-lint,
as I mentioned recently in cfe-dev mailing list.
This patch adds a new check in readability module:
readability-inconsistent-declaration-parameter-name. I also added appropriate
testcases and documentation.
I chose readability module, as it seems it is the best place for it.
I think I followed the rules of LLVM coding guideline, but I may have missed
something, as I usually use other code formatting style.

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.

Patch by Beren Minor!
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.
