New Compiler Flags
------------------
-- :option:`-fstrict-float-cast-overflow` and
- :option:`-fno-strict-float-cast-overflow`.
+- ``-fstrict-float-cast-overflow`` and ``-fno-strict-float-cast-overflow``.
When a floating-point value is not representable in a destination integer
type, the code has undefined behavior according to the language standard. By
'no-strict' option, Clang attempts to match the overflowing behavior of the
target's native float-to-int conversion instructions.
-- :option: `-fforce-emit-vtables` and `-fno-force-emit-vtables`.
+- ``-fforce-emit-vtables`` and ``-fno-force-emit-vtables``.
In order to improve devirtualization, forces emitting of vtables even in
modules where it isn't necessary. It causes more inline virtual functions
