[PATCH] D152405: [WIP][clang] Add experimental option to omit the RTTI component from the vtable when -fno-rtti is used

[Roland McGrath via Phabricator via cfe-commits]

mcgrathr added a comment.

It's not clear from the change description if this can be enabled orthogonally to relative-vtables. I think it should be possible to choose each switch independently, thus generating 4 variants of the vtable layout ABI.

Does any runtime code (libc++abi) ever need to know the vtable layout details when actually making use of RTTI, such that it would need to adapt to this ABI change?
