 .. option:: -fuse-ctor-homing
 
-   This optimization is similar to the optimizations that are enabled as part
-   of -fno-standalone-debug. Here, Clang only emits type info for a
-   non-trivial, non-aggregate C++ class in the modules that contain a
-   definition of one of its constructors. This relies on the additional
-   assumption that all classes that are not trivially constructible have a
-   non-trivial constructor that is used somewhere. The negation,
-   -fno-use-ctor-homing, ensures that constructor homing is not used.

-   This flag is not enabled by default, and needs to be used with -cc1 or
-   -Xclang.
