--- Comment #11 from Shawn Webb <shawn.webb@hardenedbsd.org> ---
The Cross-DSO CFI implementation in llvm favors mremap, though it does contain
a fallback in the case mremap doesn't exist. If FreeBSD were to provide an
official mremap syscall implementation, both the linuxulator and llvm's
Cross-DSO CFI implementation would benefit.
