Hi
Is there any plans to port the control flow integrity from clang[1] or use
something that don't need any hardware support as CET[2].
There is allready part of it in gcc to support the CET so would it be posseble
to write a software version of it? The best would be to make something like
RAP[3] but it is patent-pending or some thing like that.
