why fiasco use -fno-rtti compile option?

[Yuxin Ren]

Do you want to use rtti in kernel or user level?

It seems to be pretty difficult to support rtti and exception handler in
run-time, especially in kernel.
I also want to know if Fiasco support exception handler in kernel or user
space.
If it supports, I want to learn to how to achieve such support.

Thanks a lot.
