These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
The handling of renaming failures and multiple usages related to those
failures is currently spread over several functions. Identifying the
failure NamedDecl for a given usage is also duplicated, once when
creating failures and again when identify usages. There are currently
two ways to a failed NamedDecl from a usage: use the canonical decl or
use the overridden method. With new methods about to be added, a cleanup
was in order.
The data flow is simplified as follows:
* The visitor always forwards NamedDecls to addUsage(NamedDecl).
* addUsage(NamedDecl) determines the failed NamedDecl and determines
potential new names based on that failure. Usages are registered using
addUsage(NamingCheckId).
* addUsage(NamingCheckId) is now protected and its single responsibility
is maintaining the integrity of the failure/usage map.
This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

There's many instances in clang tidy checks where owning strings are used when we already have a stable string from the options, so using a StringRef makes much more sense.

Summary:
Sometimes in templated code Member references are reported as `DependentScopeMemberExpr` because that's what the standard dictates, however in many trivial cases it is easy to resolve the reference to its actual Member.
Take this code:
```
template<typename T>
class A{
int value;
A& operator=(const A& Other){
value = Other.value;
this->value = Other.value;
return *this;
}
};
```
When ran with `clang-tidy file.cpp -checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.MemberPrefix, value: m_}]}" -fix`
Current behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.value;
this->value = Other.value;
return *this;
}
};
```
As `this->value` and `Other.value` are Dependent they are ignored when creating the fix-its, however this can easily be resolved.
Proposed behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.m_value;
this->m_value = Other.m_value;
return *this;
}
};
```

Added FixItHint comments to ReservedIdentifierCheck and IdentifierNamingCheck to trick the python scripts into detecting a fix it is provided as it can't see the FixItHints in RenamerClangTidyCheck.cpp
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
This patch adds bugprone-reserved-identifier, which flags uses of __names _Like
::_this, which are reserved for the implementation. The check can optionally be
inverted, i.e. configured to flag any names that are _not_ reserved, which may
be useful for e.g. standard library implementors.
