Fangrui Song 258a959084 [clang-tidy] Add `readability-simd-intrinsics` check.
Summary:
Many architectures provide SIMD operations (e.g. x86 SSE/AVX, Power AltiVec/VSX,
ARM NEON). It is common that SIMD code implementing the same algorithm, is
written in multiple target-dispatching pieces to optimize for different
architectures or micro-architectures.

The C++ standard proposal P0214 and its extensions cover many common SIMD
operations. By migrating from target-dependent intrinsics to P0214 operations,
the SIMD code can be simplified and pieces for different targets can be unified.

Refer to http://wg21.link/p0214 for introduction and motivation for the
data-parallel standard library.

Ben Hamilton f94c10d91a [clang-tidy objc-property-declaration] New option IncludeDefaultAcronyms
Summary:
The existing option objc-property-declaration.Acronyms
replaces the built-in set of acronyms.

While this behavior is OK for clients that don't want the default
behavior, many clients may just want to add their own custom acronyms
to the default list.

This revision introduces a new option,
objc-property-declaration.IncludeDefaultAcronyms, which controls
whether the acronyms in objc-property-declaration.Acronyms are
appended to the default list (the default behavior) or whether they
replace.

I also updated the documentation.

Jonas Toth f22f3489d7 [clang-tidy] implement check for goto
The usage of `goto` is discourage in C++ since forever. This check implements
a warning for every `goto`. Even though there are (rare) valid use cases for
`goto`, better high level constructs should be used.

`goto` is used sometimes in C programs to free resources at the end of 
functions in the case of errors. This pattern is better implemented with
RAII in C++.

Summary:
This check searches for missing `else` branches in `if-else if`-chains and
missing `default` labels in `switch` statements, that use integers as condition.

It is very similar to -Wswitch, but concentrates on integers only, since enums are
already covered.

The option to warn for missing `else` branches is deactivated by default, since it is
very noise on larger code bases.

Running it on LLVM:
{F5354858} for default configuration
{F5354866} just for llvm/lib/Analysis/ScalarEvolution.cpp, the else-path checker is very noisy!

Gabor Horvath ec87e17c84 [clang-tidy] Misc redundant expressions checker updated for macros
Redundant Expression Checker is updated to be able to detect expressions that
contain macros. Also, other small details are modified to improve the current
implementation.

The improvements in detail are as follows:
* Binary and ternary operator expressions containing two constants, with at
least one of them from a macro, are detected and tested for redundancy.

Macro expressions are treated somewhat differently from other expressions,
because the particular values of macros can vary across builds.
They can be considered correct and intentional, even if macro values equal,
produce ranges that exclude each other or fully overlap, etc. 

* The code structure is slightly modified: typos are corrected,
comments are added and some functions are renamed to improve comprehensibility,
both in the checker and the test file. A few test cases are moved to another
function.

* The checker is now able to detect redundant CXXFunctionalCastExprs as well.
A corresponding test case is added.

Haojian Wu 5529a244e1 Add new check in google module for Objective-C code to ensure global variables follow the naming convention of Google Objective-C Style Guide
Summary:
This is a new checker for objc files in clang-tidy.

The new check finds global variable declarations in Objective-C files that are not follow the pattern of variable names in Google's Objective-C Style Guide.

All the global variables should follow the pattern of "g[A-Z].*" (variables) or "k[A-Z].*" (constants). The check will suggest a variable name that follows the pattern
if it can be inferred from the original name.

Haojian Wu e010406e28 [clang-tidy ObjC] [3/3] New check objc-forbidden-subclassing
Summary:
This is part 3 of 3 of a series of changes to improve Objective-C
linting in clang-tidy.

This adds a new clang-tidy check `objc-forbidden-subclassing` which
ensures clients do not create subclasses of Objective-C classes which
are not designed to be subclassed.

(Note that for code under your control, you should use
__attribute__((objc_subclassing_restricted)) instead -- this
is intended for third-party APIs which cannot be modified.)

By default, the following classes (which are publicly documented
as not supporting subclassing) are forbidden from subclassing:

ABNewPersonViewController
ABPeoplePickerNavigationController
ABPersonViewController
ABUnknownPersonViewController
NSHashTable
NSMapTable
NSPointerArray
NSPointerFunctions
NSTimer
UIActionSheet
UIAlertView
UIImagePickerController
UITextInputMode
UIWebView

Clients can set a CheckOption
`objc-forbidden-subclassing.ClassNames` to a semicolon-separated
list of class names, which overrides this list.

Test Plan: `ninja check-clang-tools`

Jonas Toth c9aea86e6a [clang-tidy] introduce legacy resource functions to 'cppcoreguidelines-owning-memory'
Summary:
This patch introduces support for legacy C-style resource functions that must obey
the 'owner<>' semantics.

- added legacy creators like malloc,fopen,...
- added legacy consumers like free,fclose,...

This helps codes that mostly benefit from owner:
Legacy, C-Style code that isn't feasable to port directly to RAII but needs a step in between
to identify actual resource management and just using the resources.

Jonas Toth 6ccc1c342a [clang-tidy] Implement type-based check for `gsl::owner`
This check implements the typebased semantic of `gsl::owner`.
Meaning, that 
- only `gsl::owner` is allowed to get `delete`d
- `new` expression must be assigned to `gsl::owner`
- function calls that expect `gsl::owner` as argument, must get either an owner
  or a newly created and recognized resource (in the moment only `new`ed memory)
- assignment to `gsl::owner` must be either a resource or another owner
- functions returning an `gsl::owner` are considered as factories, and their result
  must be assigned to an `gsl::owner`
- classes that have an `gsl::owner`-member must declare a non-default destructor

There are some problems that occur when typededuction is in place.
For example `auto Var = function_that_returns_owner();` the type of `Var` will not be
an `gsl::owner`. This case is catched, and explicitly noted.

But cases like fully templated functions
```
template <typename T> 
void f(T t) { delete t; }
// ...
f(gsl::owner<int*>(new int(42)));
```
Will created false positive (the deletion is problematic), since the type deduction
removes the wrapping `typeAlias`.

Summary:
Finds compound statements which create next nesting level after `NestingThreshold` and emits a warning.
Do note that it warns about each compound statement that breaches the threshold, but not any of it's sub-statements, to have readable warnings.

I was able to find only one coding style referencing nesting:
  - https://www.kernel.org/doc/html/v4.10/process/coding-style.html#indentation
     > In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep.

This seems too basic, i'm not sure what else to test. Are more tests needed?

Jakub Kuderski 4cdeb41072 [clang-tidy] modernize-use-emplace: Remove unnecessary make_tuple calls
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);
```

This helps e.g. when running this check on cppunit client code where the
macro is provided by the system, so there is no easy way to modify it.

Jakub Kuderski 2a43d71765 [clang-tidy] modernize-use-emplace: remove unnecessary make_pair calls
Summary:
When there is a push_back with a call to make_pair, turn it into emplace_back and remove the unnecessary make_pair call.

Eg.

```
std::vector<std::pair<int, int>> v;
v.push_back(std::make_pair(1, 2)); // --> v.emplace_back(1, 2);
```

make_pair doesn't get removed when explicit template parameters are provided, because of potential problems with type conversions.

Haojian Wu c5cc03377e [clang-tidy] Add a clang-tidy check for possible inefficient vector operations
Summary:
The "performance-inefficient-vector-operation" check finds vector oprations in
for-loop statements which may cause multiple memory reallocations.

This is the first version, only detects typical for-loop:

```
std::vector<int> v;
for (int i = 0; i < n; ++i) {
  v.push_back(i);
}

// or

for (int i = 0; i < v2.size(); ++i) {
  v.push_back(v2[i]);
}
```

We can extend it to handle more cases like for-range loop in the future.

Summary:
This checker flags the use of C-style memory management functionality and notes about modern alternatives.
In an earlier revision it tried to autofix some kind of patterns, but that was a bad idea. Since memory management can be so widespread in a program, manual updating is most likely necessary.
Maybe for special cases, there could be later additions to this basic checker.

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

Martin Bohme b1ce6c6d57 [clang-tidy] Add check 'misc-move-forwarding-reference'
Summary:
The check emits a warning if std::move() is applied to a forwarding reference, i.e. an rvalue reference of a function template argument type.

If a developer is unaware of the special rules for template argument deduction on forwarding references, it will seem reasonable to apply std::move() to the forwarding reference, in the same way that this would be done for a "normal" rvalue reference.

This has a consequence that is usually unwanted and possibly surprising: If the function that takes the forwarding reference as its parameter is called with an lvalue, that lvalue will be moved from (and hence placed into an indeterminate state) even though no std::move() was applied to the lvalue at the callsite.

As a fix, the check will suggest replacing the std::move() with a std::forward().

This patch requires D23004 to be submitted before it.

Alexander Droste 1512f9a0f9 [clang-tidy] MPIBufferDerefCheck
...
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.

Kirill Bobyrev 8694cb97c2 [clang-tidy] minor improvements in modernise-deprecated-headers check
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++.

Felix Berger 7f8827576c [clang-tidy] UnnecessaryValueParamCheck - suggest std::move() if non-const value parameter can be moved.
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.

Alexander Kornienko 28b34b043e [clang-tidy] misc-move-const-arg: Detect if result of std::move() is being passed as a const ref argument
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.

Alexander Kornienko c0308c451b [clang-tidy] modernize-use-auto: don't remove stars by default
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;`.

Etienne Bergeron bda187decd [clang-tidy] New checker for redundant expressions.
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
    {

Etienne Bergeron bae829ede5 [clang-tidy] Add new checker for comparison with runtime string functions.
Summary:
This checker is validating suspicious usage of string compare functions.

Example:
```
  if (strcmp(...))       // Implicitly compare to zero
  if (!strcmp(...))      // Won't warn
  if (strcmp(...) != 0)  // Won't warn
```

This patch was checked over large amount of code.
There is three checks:
  [*] Implicit comparator to zero (coding-style, many warnings found),
  [*] Suspicious implicit cast to non-integral (bugs!?, almost none found),
  [*] Comparison to suspicious constant (bugs!?, found two cases),

Example:
[[https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c |
https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c]]

```
      else if(strcmp(id, "select") == 0)
      {

      }
      else if(strcmp(id, "sk") == 28)      // BUG!?

         array->array[i].key1 = 20;

Etienne Bergeron 1f696b316c [clang-tidy] Add new checker for suspicious sizeof expressions
Summary:
This check is finding suspicious cases of sizeof expression.

Sizeof expression is returning the size (in bytes) of a type or an
expression. Programmers often abuse or misuse this expression.

This checker is adding common set of patterns to detect some
of these bad constructs.


Some examples found by this checker:

R/packages/ifultools/ifultools/src/fra_neig.c
```
        /* free buffer memory */
        (void) mutil_free( dist_buff, sizeof( ctr * sizeof( double ) ) );
        (void) mutil_free( nidx_buff, sizeof( ctr * sizeof( sint32 ) ) );
```

```
static Dtdisc_t mapDisc = {
    offsetof(item, p),
    sizeof(2 * sizeof(void *)),
    offsetof(item, link),

    (Dtfree_f) freeItem,
    (Dtcompar_f) cmpItem,
    NIL(Dthash_f),
    NIL(Dtmemory_f),
    NIL(Dtevent_f)
};
```


mDNSResponder/mDNSShared/dnsextd.c
```
	context = ( TCPContext* ) malloc( sizeof( TCPContext ) );
	require_action( context, exit, err = mStatus_NoMemoryErr; LogErr( "AcceptTCPConnection", "malloc" ) );
	mDNSPlatformMemZero( context, sizeof( sizeof( TCPContext ) ) );
	context->d		 = self;

Gabor Horvath 5273f615c4 [clang-tidy] Extension of checker misc-misplaced-widening-cast
Summary:
Existing checker misc-misplaced-widening-cast was extended:
- New use cases: casted expression as lhs or rhs of a logical comparison or function argument
- New types: beside int, long and long long various char types, short and int128 added
- New option to check implicit casts: forgetting a cast is at least as common and as dangerous as misplacing it. This option can be disabled.

This patch depends on AST Matcher patches D17986 and D18243 and also contains fix for checker misc-bool-pointer-implicit-conversion needed because of the fix in the AST Matcher patch.

Etienne Bergeron 3e4adf1762 [clang-tidy] Add a new checker to detect missing comma in initializer list.
Summary:
This checker is able to detect missing comma in 
an array of string literals.

```
  const char* A[] = {
    "abc",
    "def"   // missing comma (no compiler warnings)
    "ghi",
  };
```

The ratio of false-positive is reduced by restricting the
size of the array considered and the ratio of missing
comma.

To validate the quantity of false positive, the checker
was tried over LLVM and chromium code and detected these
cases:

Felix Berger ffae543b39 [clang-tidy] ClangTidy check to flag uninitialized builtin and pointer fields.
Summary:
This patch is a continuation of http://reviews.llvm.org/D10553 by Jonathan B Coe.

The main additions are:

1. For C++11 the check suggests in-class field initialization as fix. This
makes the fields future proof towards the addition of new constructors.
2 For older language versions the fields are added in the right position
in the initializer list with more tests.
3. User documentation.
