Summary:
Added support for macro definitions.
--
1. Added a pre-processor callback to catch macro definitions
2. Changed the type of the failure map so that macros and declarations can share the same map
3. Added extra tests to ensure fix-ups work using the new map
4. Added fix-ups for type aliases in variable and function declarations as part of adding the new tests

Differential Revision: http://reviews.llvm.org/D21020
llvm-svn: 272993
Summary:
Conceptually, this is very close to the existing functionality of misc-move-const-arg, which is why I'm adding it here and not creating a new check. For example, for a type A that is both movable and copyable, this
const A a1;
A a2(std::move(a1));
is not only a case where a const argument is being passed to std::move(), but the result of std::move() is also being passed as a const reference (due to overload resolution).
The new check typically triggers (exclusively) in cases where people think they're dealing with a movable type, but in fact the type is not movable.

Differential Revision: http://reviews.llvm.org/D21223
llvm-svn: 272896
Summary:
By default, modernize-use-auto check will retain stars when replacing an explicit type with `auto`: `MyType *t = new MyType;` will be changed to `auto *t = new MyType;`, thus resulting in more consistency with the recommendations to use `auto *` for iterating over pointers in range-based for loops: http://llvm.org/docs/CodingStandards.html#beware-unnecessary-copies-with-auto
The new `RemoveStars` option allows to revert to the old behavior: with the new option turned on the check will change `MyType *t = new MyType;` to `auto t = new MyType;`.

Summary:
This patch is adding support for conditional expression and overloaded operators.
To decrease false-positive, this patch is adding a list of banned macro names that
has multiple variant with same integer value.
Also fixed support for template instantiation and added an unittest.

Because modernize-make-shared do almost the same job as
modernize-make-unique, I refactored common code to MakeSmartPtrCheck.

llvm-svn: 268253
Summary:
This checker finds redundant expression on both side of a binary operator.
The current implementation provide a function to check whether expressions
are equivalent. This implementation is able to recognize the common
subset encounter in C++ program. Side-effects like "x++" are not considered
to be equivalent.
There are many False Positives related to macros and to floating point
computations (detecting NaN). The checker is ignoring these cases.
Example:
```
if( !dst || dst->depth != desired_depth ||
dst->nChannels != desired_num_channels ||
dst_size.width != src_size.width ||
dst_size.height != dst_size.height ) <<--- bug
{
```

Summary:
For folds (e.g. std::accumulate), check matches between the provided init value and the range's value_type. A typical error is "std::accumulate(begin, end, 0);", where begin and end have float value_type. See the documentation for more examples.
For now we check std::accumulate, std::reduce and std::inner_product.

Summary:
Checker to validate string constructor parameters.
A common mistake is to swap parameter for the fill-constructor.
```
std::string str('x', 4);
std::string str('4', x);

Summary:
The check detects multi-statement macros that are used in unbraced conditionals.
Only the first statement will be part of the conditionals and the rest will fall
outside of it and executed unconditionally.

llvm-svn: 266333
Summary: Added the remaining features needed to satisfy C++ Core Guideline Type.6: Always initialize a member variable to cppcoreguidelines-pro-type-member-init. The check now flags all default-constructed uses of record types without user-provided default constructors that would leave their memory in an undefined state. The check suggests value initializing them instead.
