Summary:
This check finds macro expansions of `DISALLOW_COPY_AND_ASSIGN(Type)` and
replaces them with a deleted copy constructor and a deleted assignment operator.
Before the `delete` keyword was introduced in C++11 it was common practice to
declare a copy constructor and an assignment operator as a private members. This
effectively makes them unusable to the public API of a class.
With the advent of the `delete` keyword in C++11 we can abandon the
`private` access of the copy constructor and the assignment operator and
delete the methods entirely.
Migration example:
```
lang=dif
class Foo {
private:
- DISALLOW_COPY_AND_ASSIGN(Foo);
+ Foo(const Foo &) = delete;
+ const Foo &operator=(const Foo &) = delete;
};
```

Summary:
Sometimes in templated code Member references are reported as `DependentScopeMemberExpr` because that's what the standard dictates, however in many trivial cases it is easy to resolve the reference to its actual Member.
Take this code:
```
template<typename T>
class A{
int value;
A& operator=(const A& Other){
value = Other.value;
this->value = Other.value;
return *this;
}
};
```
When ran with `clang-tidy file.cpp -checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.MemberPrefix, value: m_}]}" -fix`
Current behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.value;
this->value = Other.value;
return *this;
}
};
```
As `this->value` and `Other.value` are Dependent they are ignored when creating the fix-its, however this can easily be resolved.
Proposed behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.m_value;
this->m_value = Other.m_value;
return *this;
}
};

To cover STR34-C rule's second use case, where ``signed char`` is

There is another clang-tidy check which catches these cases.
cppcoreguidelines-pro-bounds-constant-array-index catches any
indexing which is not integer constant. I think this check is
very strict about the index (e.g. constant), so it's still useful
to cover the ``signed char`` use case in this check, so we
can provide a way to catch the SEI cert rule's use cases on a
codebase, where this CPP guideline is not used.

Summary:
Recursion is a powerful tool, but like any tool
without care it can be dangerous. For example,
if the recursion is unbounded, you will
eventually run out of stack and crash.
You can of course track the recursion depth
but if it is hardcoded, there can always be some
other environment when that depth is too large,
so said magic number would need to be env-dependent.
But then your program's behavior is suddenly more env-dependent.
Also, recursion, while it does not outright stop optimization,
recursive calls are less great than normal calls,
for example they hinder inlining.
Recursion is banned in some coding guidelines:
* SEI CERT DCL56-CPP. Avoid cycles during initialization of static objects
* JPL 2.4 Do not use direct or indirect recursion.
* I'd say it is frowned upon in LLVM, although not banned
And is plain unsupported in some cases:
* OpenCL 1.2, 6.9 Restrictions: i. Recursion is not supported.
So there's clearly a lot of reasons why one might want to
avoid recursion, and replace it with worklist handling.
It would be great to have a enforcement for it though.
This implements such a check.
Here we detect both direct and indirect recursive calls,
although since clang-tidy (unlike clang static analyzer)
is CTU-unaware, if the recursion transcends a single standalone TU,
we will naturally not find it :/
The algorithm is pretty straight-forward:
1. Build call-graph for the entire TU.
For that, the existing `clang::CallGraph` is re-used,
although it had to be modified to also track the location of the call.
2. Then, the hard problem: how do we detect recursion?
Since we have a graph, let's just do the sane thing,
and look for Strongly Connected Function Declarations - widely known as `SCC`.
For that LLVM provides `llvm::scc_iterator`,
which is internally an Tarjan's DFS algorithm, and is used throught LLVM,
so this should be as performant as possible.
3. Now that we've got SCC's, we discard those that don't contain loops.
Note that there may be more than one loop in SCC!
4. For each loopy SCC, we call out each function, and print a single example
call graph that shows recursion -- it didn't seem worthwhile enumerating
every possible loop in SCC, although i suppose it could be implemented.
* To come up with that call graph cycle example, we start at first SCC node,
see which callee of the node is within SCC (and is thus known to be in cycle),
and recurse into it until we hit the callee that is already in call stack.

Summary:
It now handles `typedef`s that include comma-separated multiple types, and handles embedded struct definitions, which previously could not be automatically converted.
For example, with this patch `modernize-use-using` now can convert:
typedef struct { int a; } R_t, *R_p;
to:
using R_t = struct { int a; };
using R_p = R_t*;
`-ast-dump` showed that the `CXXRecordDecl` definitions and multiple `TypedefDecl`s come consecutively in the tree, so `check()` stores information between calls to determine when it is receiving a second or additional `TypedefDecl` within a single `typedef`, or when the current `TypedefDecl` refers to an embedded `CXXRecordDecl` like a `struct`.

Differential Revision: https://reviews.llvm.org/D70270
Summary:
This check searches for signed char -> integer conversions which might
indicate programming error, because of the misinterpretation of char
values. A signed char might store the non-ASCII characters as negative
values. The human programmer probably expects that after an integer
conversion the converted value matches with the character code
(a value from [0..255]), however, the actual value is in
[-128..127] interval.
See also:
STR34-C. Cast characters to unsigned char before converting to larger integer sizes
<https://wiki.sei.cmu.edu/confluence/display/c/STR34-C.+Cast+characters+to+unsigned+char+before+converting+to+larger+integer+sizes>
By now this check is limited to assignment / variable declarations.
If we would catch all signed char -> integer conversion, then it would
produce a lot of findings and also false positives. So I added only
this use case now, but this check can be extended with additional
use cases later.
The CERT documentation mentions another use case when the char is
used for array subscript. Next to that a third use case can be
the signed char - unsigned char comparison, which also a use case
where things happen unexpectedly because of conversion to integer.

Summary:
readability-redundant-member-init removes redundant / unnecessary member and base class initialization. Unfortunately for the specific case of a copy constructor's initialization of a base class, gcc at strict warning levels warns if "base class is not initialized in the copy constructor of a derived class".
This patch adds an option `IgnoreBaseInCopyConstructors` defaulting to 0 (thus maintaining current behavior by default) to skip the specific case of removal of redundant base class initialization in the copy constructor. Enabling this option enables the resulting code to continue to compile successfully under `gcc -Werror=extra`. New test cases `WithCopyConstructor1` and `WithCopyConstructor2` in clang-tools-extra/test/clang-tidy/readability-redundant-member-init.cpp show that it removes redundant members even from copy constructors.

Summary:
In addition to adding `override` wherever possible, clang-tidy's `modernize-use-override` nicely removes `virtual` when `override` or `final` is specified, and further removes override when final is specified. While this is great default behavior, when code needs to be compiled with gcc at high warning levels that include `gcc -Wsuggest-override` or `gcc -Werror=suggest-override`, clang-tidy's removal of the redundant `override` keyword causes gcc to emit a warning or error. This discrepancy / conflict has been noted by others including a comment on Stack Overflow and by Mozilla's Firefox developers.
This patch adds an AllowOverrideAndFinal option defaulting to 0 - thus preserving current behavior - that when enabled allows both `override` and `final` to co-exist, while still fixing all other issues.
The patch includes a test file verifying all combinations of virtual/override/final, and mentions the new option in the release notes.

Summary:
`readability-redundant-string-init` was one of several clang-tidy checks documented as failing for C++17. (The failure mode in C++17 is that it changes `std::string Name = ""`; to `std::string Name = Name;`, which actually compiles but crashes at run-time.)
Analyzing the AST with `clang -Xclang -ast-dump` showed that the outer `CXXConstructExprs` that previously held the correct SourceRange were being elided in C++17/2a, but the containing `VarDecl` expressions still had all the relevant information. So this patch changes the fix to get its source ranges from `VarDecl`.
It adds one test `std::string g = "u", h = "", i = "uuu", j = "", k;` to confirm proper warnings and fixit replacements in a single `DeclStmt` where some strings require replacement and others don't. The readability-redundant-string-init.cpp and readability-redundant-string-init-msvc.cpp tests now pass for C++11/14/17/2a.
