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.

This reverts commit r310630.
The new code broke on Windows and was untested. On Linux, it was
selecting the "int" overload of operator<<, which definitely does not
print the right thing when fed a "Mode" char.
llvm-svn: 310661
Summary:
1. Refactor the structure of the code by adding a base class for all close-on-exec checks, which implements most of the needed functions.
2. memfd_create() is better to set MFD_CLOEXEC flag to avoid file descriptor leakage.

operation like "->" or ".", this could happen in a subclass of the

Summary:
This patch renames checks, check options and changes messages to use correct
term "implicit conversion" instead of "implicit cast" (which has been in use in
Clang AST since ~10 years, but it's still technically incorrect w.r.t. C++
standard).

Don't warn about initializing members of an anonymous union.

Created new module bugprone and placed the check in that.
Finds memset() calls with potential mistakes in their arguments.
Replaces and extends the existing google-runtime-memset-zero-length check.
Cases covered:
* Fill value is a character '0'. Integer 0 might have been intended.
* Fill value is out of char range and gets truncated.
* Byte count is zero. Potentially swapped with the fill value argument.

Tests would go flaky if;
1. Using %T (not %t)
2. Put a file with common name like header.h into %T
3. Other tests (eg. misc-unused-parameters.cpp) are doing as well
We should avoid using %T unless it really makes sense.

llvm-svn: 307661
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.
