Summary:
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.
Instructions on how to apply the check can be found at: https://github.com/0ax1/MPI-Checker/tree/master/examples

Patch by Alexander Droste!
Differential Revision: https://reviews.llvm.org/D21962
llvm-svn: 276640
TemplateFunctionFindBy{Declaration|Use}.cpp contained typos and therefore were
failing. clang-rename passes these tests after typos are fixed.
llvm-svn: 276620
This patch introduces:
* TypeLoc visiting, which helps a lot in renaming types
* NestedNameSpecifierLoc visiting (through getting them via ASTMatcher at the moment, though, because RecursiveASTVisitor<T>::VisitNestedNameSpecifierLoc isn't implemented), which helps to treat nested names correctly
* better code formatting and refactoring
* bunch of tests

Summary:
Previoly, the added test failed with the fillowing fixit:
char v[5];
- for(size_t i = 0; i < 5; ++i)
+ for(char value : v)
{
- unsigned char value = v[i];
if (value > 127)
i.e. the variable 'value' changes from unsigned char to signed char. And
thus the following 'if' does not work anymore.
With this commit, the fixit is changed to:
char v[5];
- for(size_t i = 0; i < 5; ++i)
+ for(unsigned char value : v)
{
- unsigned char value = v[i];
if (value > 127)

Summary:
When the expression is value dependent,
isIntegerConstantExpr() crashes in C++03 mode with
../tools/clang/lib/AST/ExprConstant.cpp:9330: (anonymous namespace)::ICEDiag CheckICE(const clang::Expr *, const clang::ASTContext &):
Assertion `!E->isValueDependent() && "Should not see value dependent exprs!"' failed.
In C++11 mode, that assert does not trigger.
This commit works around this in the check. We don't check
value-dependent indices and instead check their specialization.

This patch does the following:
* enforces proper formatting for few files (i.e. deals with 80 linewidth violations and few other things)
* ensures '\n' chars are passed to the output streams instead of "\n" strings
* fixes a bug caused by calling cl::PrintHelpMessage(), which occasionally calls exit(0), so that exit(1) (which is right after cl::PrintHelpMessage line) becomes dead code

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.

As it failed on e.g.

Trouble iterating over directory '/home/buildbots/ppc64be-clang-test/clang-ppc64be/stage1/tools/clang/tools/extra/test/clang-rename/Output': No such file or directory
A reliable way to trigger the problem locally is to run all clang-rename
tests in parallel in a loop:
for i in $(seq 1 100); do ~/git/llvm/workdir/bin/llvm-lit -v -j15 . || break; done
Change the test script to be more similar to test/Tooling/clang-check.cpp, that
way the above command doesn't fail for me anymore.

Use case: a class is declared in a header, and defined in two
translation units. clang-rename is asked to rename a class member that's
referenced in both translation units.
Using -i is not possible, as in case the first clang-rename invocation
touches the header, the second invocation will result in compilation
errors. Using -export-fixes handles this situation, each invocation can
work on the original source, and at the end the user can apply the
replacements with clang-apply-replacements.

This is similar to -offset with the following differences:
1) -offset can refer to local variables as well.
2) -old-name makes it easier to refer to e.g. ClassName::MemberName by
spelling out the fully qualified name, instead of having to use e.g.
grep to look up the exact offset.
In other words, -offset is great when clang-rename is invoked by e.g. an
IDE, but not really user-friendly when the tool is invoked by the user
from commandline. That's the use case where -old-name is supposed to
improve the situation.

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.

Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").
Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

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;`.

If prefix search finds something where nothing can be nested under (e.g.
a variable or macro) don't add it to the result.
This is for cases like:
header.h:
extern int a;
file.cc:
namespace a {
SOME_MACRO
}
We will look up a::SOME_MACRO, which doesn't have any results. Then we
look up 'a' and find something before we ever look up just 'SOME_MACRO'.
With some basic filtering we can avoid this case.
