Although it is not explicitly stated in LLVM Coding Standards, LLVM developers
prefer to omit braces around flow control statements with single line body.
For example the following piece of code
```
if (condition)
std::cout << "Hello, world!" << std::endl;
```
is preferred to
```
if (condition) {
std::cout << "Hello, world!" << std::endl;
}
```
So far clang-rename has ignored this. This patch makes clang-rename more

Summary:
The check emits a warning if std::move() is applied to a forwarding reference, i.e. an rvalue reference of a function template argument type.
If a developer is unaware of the special rules for template argument deduction on forwarding references, it will seem reasonable to apply std::move() to the forwarding reference, in the same way that this would be done for a "normal" rvalue reference.
This has a consequence that is usually unwanted and possibly surprising: If the function that takes the forwarding reference as its parameter is called with an lvalue, that lvalue will be moved from (and hence placed into an indeterminate state) even though no std::move() was applied to the lvalue at the callsite.
As a fix, the check will suggest replacing the std::move() with a std::forward().
This patch requires D23004 to be submitted before it.

As Alexander pointed out, LLVM Coding Standards are more conservative about
using auto, i.e. it should be used in the following situations:
* When the type is obvious, i.e. explicitly mentioned in the same expression.
For example `if (const clang::FieldDecl *FieldDecl = Initializer->getMember())`.
* When the type is totally non-obvious and one iterates over something. For
example
`for (const auto &CurrDecl : Context.getTranslationUnitDecl()->decls())`.
Otherwise the type should be explicitly stated.

The include order check would get notified of all include
directives in a depth-first manner. This created the
possibility of an include directive from a header file
interfering with the sort order of a set of two distinct

was on just the right line.
With this patch we bucket the include directives by the file

so that directives from different files do not get mixed

This differs from the previous version by being more careful about template
instantiation/specialization in order to prevent errors when building with
clang -Werror. Specifically:
* begin is not defined in the template and is instead instantiated when Head
is. I think the warning when we don't do that is wrong (PR28815) but for now
at least do it this way to avoid the warning.
* Instead of performing template specializations in LLVM_INSTANTIATE_REGISTRY
instead provide a template definition then do explicit instantiation. No
compiler I've tried has problems with doing it the other way, but strictly
speaking it's not permitted by the C++ standard so better safe than sorry.
Original commit message:
Currently the Registry class contains the vestiges of a previous attempt to
allow plugins to be used on Windows without using BUILD_SHARED_LIBS, where a
plugin would have its own copy of a registry and export it to be imported by
the tool that's loading the plugin. This only works if the plugin is entirely
self-contained with the only interface between the plugin and tool being the
registry, and in particular this conflicts with how IR pass plugins work.
This patch changes things so that instead the add_node function of the registry
is exported by the tool and then imported by the plugin, which solves this
problem and also means that instead of every plugin having to export every
registry they use instead LLVM only has to export the add_node functions. This
allows plugins that use a registry to work on Windows if
LLVM_EXPORT_SYMBOLS_FOR_PLUGINS is used.

2. Fix virtual function and its overriding functions renaming. Renaming a

Summary:
include-fixer will firstly try to use scoped namespace context information to
search identifier. However, in some cases, it's unsafe to do nested class
search, because it might treat the identifier as a nested class of scoped
namespace.
Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".
namespace foo { Bar t; }
Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

The complexity of renaming a USR is O(N) [N stands for number of nodes in
Translation Unit]. In some cases there are more than one USR for a single symbol
(see overridden functions and ctor/dtor handling), which means that the
complexity of finding all of the corresponding USRs is O(N * M) [M stands for
number of USRs corresponding to the symbols, which may be not quite small]. With
a simple tweak we can make it O(N * log(M)) by passing whole list of USRs
corresponding to the symbol to USRLocFinder.

Summary:
Make check more useful in the following two cases:
The parameter is passed by non-const value, has a non-deleted move constructor and is only referenced once in the function as argument to the type's copy constructor.
The parameter is passed by non-const value, has a non-deleted move assignment operator and is only referenced once in the function as argument of the the type's copy assignment operator.
In this case suggest a fix to move the parameter which avoids the unnecessary copy and is closest to what the user might have intended.

We match on the generated FunctionDecl of the lambda and try to fix it.
This causes a crash.
The right behavior is to ignore lambdas, because they are a definition.

As it failed on e.g.
<http://lab.llvm.org:8011/builders/clang-ppc64be-linux/builds/7089/steps/ninja%20check%201/logs/FAIL%3A%20Clang%20Tools%3A%3AClassTestReplacements.cpp> with:
Trouble iterating over directory '/home/buildbots/ppc64be-clang-test/clang-ppc64be/stage1/tools/clang/tools/extra/test/clang-rename/Output': No such file or directory
A reliable way to trigger the problem locally is to run all clang-rename
tests in parallel in a loop:
for i in $(seq 1 100); do ~/git/llvm/workdir/bin/llvm-lit -v -j15 . || break; done
Change the test script to be more similar to test/Tooling/clang-check.cpp, that
way the above command doesn't fail for me anymore.

Use case: a class is declared in a header, and defined in two
translation units. clang-rename is asked to rename a class member that's
referenced in both translation units.
Using -i is not possible, as in case the first clang-rename invocation
touches the header, the second invocation will result in compilation
errors. Using -export-fixes handles this situation, each invocation can
work on the original source, and at the end the user can apply the
replacements with clang-apply-replacements.

This is similar to -offset with the following differences:
1) -offset can refer to local variables as well.
2) -old-name makes it easier to refer to e.g. ClassName::MemberName by
spelling out the fully qualified name, instead of having to use e.g.
grep to look up the exact offset.
In other words, -offset is great when clang-rename is invoked by e.g. an
IDE, but not really user-friendly when the tool is invoked by the user
from commandline. That's the use case where -old-name is supposed to
improve the situation.

Summary:
Added support for macro definitions.
--
1. Added a pre-processor callback to catch macro definitions
2. Changed the type of the failure map so that macros and declarations can share the same map
3. Added extra tests to ensure fix-ups work using the new map
4. Added fix-ups for type aliases in variable and function declarations as part of adding the new tests

llvm-svn: 272993
Summary:
Conceptually, this is very close to the existing functionality of misc-move-const-arg, which is why I'm adding it here and not creating a new check. For example, for a type A that is both movable and copyable, this
const A a1;
A a2(std::move(a1));
is not only a case where a const argument is being passed to std::move(), but the result of std::move() is also being passed as a const reference (due to overload resolution).
The new check typically triggers (exclusively) in cases where people think they're dealing with a movable type, but in fact the type is not movable.

Summary:
we should only deduplicate symbols after matching symbols with the
undefined identifier. This patch tries to fix the situation where matching
symbols are deleted when it has the same header as a non-matching symbol, which
can prevent finding the correct header even if there is a matched symbol.

Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").
Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

Summary:
By default, modernize-use-auto check will retain stars when replacing an explicit type with `auto`: `MyType *t = new MyType;` will be changed to `auto *t = new MyType;`, thus resulting in more consistency with the recommendations to use `auto *` for iterating over pointers in range-based for loops: http://llvm.org/docs/CodingStandards.html#beware-unnecessary-copies-with-auto
The new `RemoveStars` option allows to revert to the old behavior: with the new option turned on the check will change `MyType *t = new MyType;` to `auto t = new MyType;`.

If prefix search finds something where nothing can be nested under (e.g.
a variable or macro) don't add it to the result.
This is for cases like:
header.h:
extern int a;
file.cc:
namespace a {
SOME_MACRO
}
We will look up a::SOME_MACRO, which doesn't have any results. Then we
look up 'a' and find something before we ever look up just 'SOME_MACRO'.
With some basic filtering we can avoid this case.

there are mutliple matching symbols in one header we take the maximum

Modified the clang-tidy PassByValue check. It now stops adding std::move to type which is trivially copyable because that caused the clang-tidy MoveConstArg to complain and revert, thus creating a cycle.
