This check will find occurrences of ``std::random_shuffle`` and replace it with ``std::shuffle``. In C++17 ``std::random_shuffle`` will no longer be available and thus we need to replace it.
Example of case that it fixes
```
std::vector<int> v;
// First example
std::random_shuffle(vec.begin(), vec.end());
```

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.

This commit renames all of the safety functionality to be hicpp, adds an appropriate LICENSE.TXT, and updates the documentation accordingly.
llvm-svn: 298229
Summary:
Hello everybody,
this is an incremental patch for the NoMalloc-Checker I wrote. It allows to configure the memory-management functions, that are checked,
This might be helpful for a code base with custom functions in use, or non-standard functionality, like posix_memalign.

llvm-svn: 296734
Summary:
Add an option to function-size to warn about high parameter counts.
This might be relevant for cppcoreguidelines and the safety module as well. Since the safety module is not landed in master already, i did not create an alias, but that can be done later as well.

to 'Limitations' isn't indented in the 'Clang-Tidy Checks' documentation page.

Summary:
Replaces explicit calls to the constructor in a return with a braced
initializer list. This way the return type is not needlessly duplicated in the
return type and the return statement.
```
Foo bar() {
Baz baz;
return Foo(baz);
}
// transforms to:
Foo bar() {
Baz baz;
return {baz};
}
```

Summary:
The documentation assumed expertise with FileCheck; many clang-tidy check
authors may not have significant exposure to FileCheck, and so it's worth

I have a created a new check for clang tidy: misc-string-compare. This will check for incorrect usage of std::string::compare when used to check equality or inequality of string instead of the string equality or inequality operators.
Example:
```
std::string str1, str2;
if (str1.compare(str2)) {
}
```

Summary:
An addition to the move-constructor-init check was duplicating the

Remove the additional check and UseCERTSemantics option.
Run the move-constructor-init test with both checks enabled.
Fix modernize-pass-by-value false-positive when initializing a base
class.
Add option to modernize-pass-by-value to only warn about parameters
that are already values.

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 :)
