Hello, i would like to suggest a fix for one of the checks in clang-tidy and i should hope this one is the correct mailing list.
The check is modernize-avoid-bind.
Consider the following:
void bar(int x, int y);
namespace N {
void bar(int x, int y);
}
void foo(){
auto Test = std::bind(N::bar,1,1);
}
clang-tidy’s modernize-avoid-bind check suggests writing:
void foo(){
auto Test =[] {return bar(1,1);};
}
instead of:
void foo(){
auto Test = [] {return N::bar(1,1);};
}
So clang-tidy has proposed an incorrect Fix.

This fixes a false-positive e.g. when string literals are returned from if statement.
This patch includes as well a small fix to includes and renames of the test suite that collided with the name of the 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++.

Summary:
D22566 will change RecursiveASTVisitor so that it descends into the initialization expressions for lambda captures.
modernize-loop-convert needs to be prepared for this so that it does not interpret these initialization expressions as invalid uses of the loop variable. The change has no ill effects without D22566 in place, i.e. the change does not depend on D22566.

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:
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;`.

Modified the clang-tidy PassByValue check. It now stops adding std::move to type which is trivially copyable because that caused the clang-tidy MoveConstArg to complain and revert, thus creating a cycle.
I have also added a lit-style test to verify the bugfix.

Summary:
Clang-tidy modernize-raw-string-literal check crashes on run-time assert while it is evaluating compiler predefined identifiers such as
- __FUNCTION__
- __func__
- __PRETTY_FUNCTION__
Check is asserting because it cannot find opening quote for such string literal. It occurs only on debug build config.
I think that it would be good to prune such cases by crossing off predefined expressions - there is no need to evaluate such matches.

Fix for __declspec attributes and const=0 without space
This patch is to address 2 problems I found with Clang-tidy:modernize-use-override.
1: missing spaces on pure function decls.
Orig:
void pure() const=0
Problem:
void pure() constoverride =0
Fixed:
void pure() const override =0
2: This is ms-extension specific, but possibly applies to other attribute types. The override is placed before the attribute which doesn’t work well with declspec as this attribute can be inherited or placed before the method identifier.
Orig:
class __declspec(dllexport) X : public Y
{
void p();
};
Problem:
class override __declspec(dllexport) class X : public Y
{
void p();
};
Fixed:
class __declspec(dllexport) class X : public Y
{
void p() override;
};

Summary:
Fix assertion failure: "Name is not a simple identifier".
`Decl::GetName` assumes the name should be an identifier. When the check
processes the function calling statement with speciail key name like
'it.operator->()', it will trigger the assert in `GetName`.
Rather than using `Decl::GetName`, we use `getNameAsString` which works
with special key names in C++.
