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.

`readability-else-after-return` only warns about `return` calls, but LLVM Coding
Standars stat that `throw`, `continue`, `goto`, etc after `return` calls are
bad, too.

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++.

Summary:
The misc-argument-comment check now ignores leading and trailing underscores and
case. The new `StrictMode` local/global option can be used to switch back to
strict checking.
Add getLocalOrGlobal version for integral types, minor cleanups.

This check verifies if buffer type and MPI (Message Passing Interface)
datatype pairs match. All MPI datatypes defined by the MPI standard (3.1)
are verified by this check. User defined typedefs, custom MPI datatypes and
null pointer constants are skipped, in the course of verification.

- rename-at is meant to be integrated with editors and works mainly off
of a location in a file, and this is the default
- rename-all is optimized for one or more oldname->newname renames, and
works with clang-apply-replacements

Patch by Kirill Bobyrev!
Differential Revision: http://reviews.llvm.org/D22129
llvm-svn: 275388
Summary:
Make check more useful in the following two cases:
The parameter is passed by non-const value, has a non-deleted move constructor and is only referenced once in the function as argument to the type's copy constructor.
The parameter is passed by non-const value, has a non-deleted move assignment operator and is only referenced once in the function as argument of the the type's copy assignment operator.
In this case suggest a fix to move the parameter which avoids the unnecessary copy and is closest to what the user might have intended.

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;`.

Because modernize-make-shared do almost the same job as
modernize-make-unique, I refactored common code to MakeSmartPtrCheck.
http://reviews.llvm.org/D19183
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.
