In 4.7 when I hovered over some method, if there was a comment above this method declaration - it was shown in pop window, now it's only declaration and no comments. Is it not possible anymore?
Comments like this were shown in the popup on hover:
// commentary
void foo();

Use doxygen style comments: either
/// Foo
void func();

or
/** Foo **/
void func();

Right, the Clang backend we use does not consider '//' for source code documentation. Please use the style Sven showed (it makes sense).

Thank you for a quick response! I see, it's a bummer for me, I use an open source library where all comments like this //
