Alexander Kornienko eedf7ec07f [clang-tidy] Fix handling of methods with try-statement as a body in modernize-use-override
Summary:
Fix generated by modernize-use-override caused syntax error when method
used try-statement as a body. `override` keyword was inserted after last
declaration token which happened to be a `try` keyword.

This fixes PR27119.

Haojian Wu b780c59b93 [clang-tidy] Fix a false positive on modernize-use-nullptr check.
Summary:
The false positive happens on two neighbour CXXDefaultArgExpr AST nodes.
like below:

```
CXXFunctionalCastExpr 0x85c9670 <col:7, col:23> 'struct ZZ' functional cast to struct ZZ <ConstructorConversion>
 `-CXXConstructExpr 0x85c9518 <col:7, col:23> 'struct ZZ' 'void (uint64, const uint64 *)'
   |-CallExpr 0x85a0a90 <col:10, col:22> 'uint64':'unsigned long long'
   | |-ImplicitCastExpr 0x85a0a78 <col:10> 'uint64 (*)(uint64)' <FunctionToPointerDecay>
   | | `-DeclRefExpr 0x85a09f0 <col:10> 'uint64 (uint64)' lvalue Function 0x85a06a0 'Hash' 'uint64 (uint64)'
   | `-CXXDefaultArgExpr 0x85a0ac8 <<invalid sloc>> 'uint64':'unsigned long long'
   `-CXXDefaultArgExpr 0x85c94f8 <<invalid sloc>> 'const uint64 *'
```

For each particular CXXDefaultArgExpr node, we need to reset
FirstSubExpr, otherwise FirstSubExpr will refer to an incorrect expr.

Alexander Kornienko ebdfb9cf0c [Clang-tidy] check for malloc, realloc and free calls
Summary:
This checker flags the use of C-style memory management functionality and notes about modern alternatives.
In an earlier revision it tried to autofix some kind of patterns, but that was a bad idea. Since memory management can be so widespread in a program, manual updating is most likely necessary.
Maybe for special cases, there could be later additions to this basic checker.

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

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

Summary:

clang-tidy would still show the warning, because
it searched for "NOLINT" only in the first line,

This caused e.g. https://llvm.org/bugs/show_bug.cgi?id=29089
(where the macro was defined in a system header). See also
the added test cases.
Now clang-tidy looks at the line of macro invocation and every line

Kirill Bobyrev acb6b35b56 [clang-tidy] Extend readability-container-size-empty to arbitrary class with size() and empty()
This patch extends readability-container-size-empty check allowing it to produce
warnings not only for STL containers, but also for containers, which provide two
functions matching following signatures:

* `size_type size() const;`
* `bool empty() const;`

Where `size_type` can be any kind of integer type.

This functionality was proposed in https://llvm.org/bugs/show_bug.cgi?id=26823

Martin Bohme b1ce6c6d57 [clang-tidy] Add check 'misc-move-forwarding-reference'
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.

Alexander Droste 1512f9a0f9 [clang-tidy] MPIBufferDerefCheck
...
This check verifies if a buffer passed to an MPI (Message Passing Interface)
function is sufficiently dereferenced. Buffers should be passed as a single
pointer or array. As MPI function signatures specify void * for their buffer
types, insufficiently dereferenced buffers can be passed, like for example
as double pointers or multidimensional arrays, without a compiler warning
emitted.

Zachary Turner 18cfbc4b8e Analyze include order on a per-file basis.
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
blocks from the top level cpp file, if that include directive
was on just the right line.

With this patch we bucket the include directives by the file
in which they appear in and process one bucket at a time,
so that directives from different files do not get mixed
together into the same list.

Kirill Bobyrev 8694cb97c2 [clang-tidy] minor improvements in modernise-deprecated-headers check
This patch introduces a minor list of changes as proposed by Richard Smith in
the mailing list.

See original comments with an impact on the future check state below:

[comments.begin

> +                          {"complex.h", "ccomplex"},

It'd be better to convert this one to <complex>, or leave it alone.
<ccomplex> is an unnecessary wart.

(The contents of C++11's <complex.h> / <ccomplex> / <complex> (all of
which are identical) aren't comparable to C99's <complex.h>, so if
this was C++98 code using the C99 header, the code will be broken with
or without this transformation.)

> +                          {"iso646.h", "ciso646"},

Just delete #includes of this one. <ciso646> does nothing.

> +              {"stdalign.h", "cstdalign"},
> +              {"stdbool.h", "cstdbool"},

We should just delete these two includes. These headers do nothing in C++.
