[Corentin Jabot via Phabricator via cfe-commits]

cor3ntin added inline comments.


================
Comment at: clang/test/CXX/expr/expr.const/p5-26.cpp:13
+    (void)static_cast<T*>(a); //cxx23-note {{cast from 'void *' is not allowed in a constant expression in C++ standards before C++2c}}
+    (void)static_cast<const T*>(a);
+    (void)static_cast<volatile T*>(a);

Why do you expect one?
you can add const/volatile (but not remove const) in a static_cast https://godbolt.org/z/qEqoEWohc
In c++23, no diag because we stop evaluating the function at that point.
