hubert.reinterpretcast added inline comments.
================
Comment at: clang/lib/Sema/SemaDeclCXX.cpp:1905
+ if (SemaRef.LangOpts.CPlusPlus2b) {
+ if (!VD->getType()->isLiteralType(SemaRef.Context))
+ SemaRef.Diag(VD->getLocation(),
----------------
This seems to trigger even when the type is dependent:
```
<stdin>:1:36: warning: definition of a variable of non-literal type in a
constexpr function is incompatible with C++ standards before C++2b
[-Wpre-c++2b-compat]
auto qq = [](auto x) { decltype(x) n; };
^
1 warning generated.
```
This also seems to emit even when `Kind` is not
`Sema::CheckConstexprKind::Diagnose` (unlike the `static`/`thread_local` case
above). Is the `CheckLiteralType` logic not reusable for this?
