Summary:
Hello, i would like to suggest a fix for one of the checks in clang-tidy.
The bug was reported in https://bugs.llvm.org/show_bug.cgi?id=38039 where you can find more information.
```
struct UOB{
UOB(const UOB &Other):j{Other.j}{}
int j;
};
```
In this case the check modernize-use-equals-default does not detect copy constructors that can be defaulted; that should be:
```
struct UOB{
UOB(const UOB &Other) = default;
int j;
};
```

It's useless and not safe to replace UTF-8 encoded with escaped ASCII to raw UTF-8 chars:
"\xE2\x98\x83" ---> <snowman>
So don't do it.

The threshold option is 'MinTypeNameLength' with default value '5'.
With MinTypeNameLength == 5 'int'/'bool' and 'const int'/'const bool'
will not be converted to 'auto', while 'unsigned' will be.

Summary:
Previously, we tried to cover all "std::initializer_list" implicit conversion
cases in the code, but there are some corner cases that not covered (see
newly-added test in the patch).
Sipping all implicit AST nodes is a better way to filter out all these cases.

Summary:
C++2a allows bitfields to have default member initializers.
Add support for this to clang-tidy's modernize-use-default-member-init check.

llvm-svn: 323208
Summary:
A follow-up fix of rL311652.
The previous `vector` in our test is different with `std::vector`, so
The check still generates fixes for std::vector (`auto p =
std::unique_ptr<Foo>(new Foo({1,2,3}))`) in real world, the patch makes the
vector behavior in test align with std::vector (both AST nodes are the same now).

Summary:
The current fix will break the compilation -- because braced list is not
deducible in std::make_unique (with the use of forwarding) without
specifying the type explicitly.
We could support it in the future.

The crash happens when calling `reset` method without any preceding

Use getAnyMember() instead of getMember() to avoid crash on anonymous
structs/unions.
Don't warn about initializing members of an anonymous union.
Fixes PR32966.

llvm-svn: 309668
Summary:
For the following code: `modernize-use-override` generates a replacement with incorrect location.
```
struct IntPair
{
int first, second;
};
struct A
{
virtual void il(IntPair);
};
struct B : A
{
void il(IntPair p = {1, (2 + 3)}) {};
// Generated Fixit: void il(IntPair p = override {1, (2 + 3)}) {};
// Should be: void il(IntPair p = {1, (2 + 3)}) override {};
};
```
This fixes that and adds a unit test.

If the class being created in unique_ptr is in anonymous nampespace, the
anonymous namespace will be included in the apply-fixes. This patch fix
this.
```

std::unique_ptr<Foo> f;
f.reset(new Foo());
// Before the change: f = std::make_unique<(annonymous namespace)::Foo>();

Before the fix, the check will give a warning on nullptr when running

Summary:
New checker to replace dynamic exception
specifications
This is an alternative to D18575 which relied on reparsing the decl to
find the location of dynamic exception specifications, but couldn't
deal with preprocessor conditionals correctly without reparsing the
entire file.
This approach uses D20428 to find dynamic exception specification
locations and handles all cases correctly.

Patch by Don Hinton!
Differential Revision: https://reviews.llvm.org/D20693
llvm-svn: 304977
Summary:
This patch makes modernize-use-emplace remove unnecessary make_ calls from push_back calls and turn them into emplace_back -- the same way make_pair calls are handled.
Custom make_ calls can be removed for custom tuple-like types -- two new options that control that are `TupleTypes` and `TupleMakeFunctions`. By default, the check removes calls to `std::make_pair` and `std::make_tuple`.
Eq.
```
std::vector<std::tuple<int, char, bool>> v;
v.push_back(std::make_tuple(1, 'A', true)); // --> v.emplace_back(1, 'A', true);
```
