Jonas Devlieghere 7319184946 [clang-tidy] Make format style customizable
Summary: I came across an outstanding FIXME to make the format style customizable. Inspired by the include fixer, I added an new option `-style` to configure the fallback style in case no clang-format configuration file is found. The default remains "llvm".

Summary:
Warn about special member functions that only contain a comment.
Report the location of the special member function, unless it is
defined in a macro.  Reporting the location of the body in a macro is
more helpful as it causes the macro expansion location to be reported too.

Eric Fiselier 732a3e0dd1 [clang-tidy] Fix identifier naming for initializer list member initializers.
Summary:
This patch adds handling for member initializers in a constructors initializer list. Previously we only handled base-class and delegating initializers, which are transformed by the `TypeLoc` matcher. For Example:

```
// Style options: All identifiers should start with an upper case letter.
struct base { ...  }; 
struct der :  base {
  int field;  // FIXES: int Field;
  der() : der(42) {} // FIXES: Der() : Der(42) {}
  der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)
  // Note that `field` doesn't get replaced
};
```

Haojian Wu 157e46dd45 [Clang-tidy]: Fix modernize-avoid-bind erroneous scope resolution.
Hello, i would like to suggest a fix for one of the checks in clang-tidy and i should hope this one is the correct mailing list.
The check is modernize-avoid-bind.

Consider the following:

  void bar(int x, int y);

  namespace N {
    void bar(int x, int y);
  }

  void foo(){
    auto Test = std::bind(N::bar,1,1);
  }

clang-tidy’s modernize-avoid-bind check suggests writing:

  void foo(){
    auto Test =[] {return bar(1,1);};
  }

instead of:

  void foo(){
    auto Test = [] {return N::bar(1,1);};
  }

So clang-tidy has proposed an incorrect Fix.

Martin Bohme 934743f8f8 [clang-tidy] Add additional diagnostic to misc-use-after-move
Summary:
This adds a diagnostic to the misc-use-after-move check that is output when the
use happens on a later loop iteration than the move, for example:

    A a;
    for (int i = 0; i < 10; ++i) {
      a.foo();
      std::move(a);
    }

This situation can be confusing to users because, in terms of source code
location, the use is above the move. This can make it look as if the warning
is a false positive, particularly if the loop is long but the use and move are
close together.

In cases like these, misc-use-after-move will now output an additional
diagnostic:

  a.cpp:393:7: note: the use happens in a later loop iteration than the move
