Msvc treats inline as a hint [0] , GCC is ambiguous [1] but I read it as utilising the hint. My under of clang [2] is that it tries to match GCC.

What the OP is saying is that it has a use to satisfy (https://en.cppreference.com/w/cpp/language/definition) and in that case it is not optional and not ignored by the compiler. Whether it will "actually" inline it is another matter, that is optional.
