Clang 15 lands support to randomize structure layout, Linux prepares to use it

In matching behavior already provided by the GCC compiler, LLVM/Clang has landed "RandStruct" functionality to allow optionally randomizing the structure layout for C code.

Hmmm, I honestly don't see much value in RandStruct. I guess it's a decent address information disclosure mitigation when paired with ASLR. The Linux crowd need to do something about sigreturn. I don't understand why you couldn't just randomize the entire Linux syscall table.
