[RFC 08/12] Add automatic structure selection compiler switch

This compiler switch allows the Randstruct feature to automatically select structures to randomize even if they're not decorated with the randomize_layout attribute. Structures can "opt out" of selection by using the no_randomize_layout attribute while this feature is active. Co-authored-by: Cole

[RFC 00/12] Introduce struct layout randomization feature

This patch set introduces structure field layout randomization into the Clang compiler. The Randstruct feature is a compile-time hardening technique that randomizes the field layout for designated structures of a code base. Admittedly, this is mostly useful for closed-source releases of code (sin
