@item --enable-vtable-verify
|
||||
Specify whether to enable or disable the vtable verification feature.
|
||||
Enabling this feature causes libstdc++ to be built with its virtual calls
|
||||
in verifiable mode. This means that, when linked with libvtv, every
|
||||
virtual call in libstdc++ will verify the vtable pointer through which the
|
||||
call will be made before actually making the call. If not linked with libvtv,
|
||||
the verifier will call stub functions (in libstdc++ itself) and do nothing.
|
||||
If vtable verification is disabled, then libstdc++ is not built with its
|
||||
virtual calls in verifiable mode at all. However the libvtv library will
|
||||
still be built (see @option{--disable-libvtv} to turn off building libvtv).
|

@option{--disable-vtable-verify} is the default.
