--- Comment #13 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- (In reply to kargls from comment #12) --- snip --- > > If you consider that the warning should be treated as significant, then > > there's an alternate implementation for the trampoline which places the > > executable fragment on the heap (we can then regulate when that heap page is > > writeable to be mutually exclusive with when it's executable) - which > > provides a measure more of security than the blanket enable on the stack. > > To use this means implementing a couple of builtin functions in libgcc and > > then dealing with enabling it. I don't know exactly what would be required > > for *BSD .. but it's probably not wildly different from Linux or Darwin - > > and we've implemented it on both of those. > > Thanks for the explanation. This looks like something that would > need to be coordinated with FreeBSD toolchain developers. The > default linker on FreeBSD is /usr/bin/ld, which is a symlink to > ld.lld. > > % ld.lld --version > LLD 18.1.6 (FreeBSD llvmorg-18.1.6-0-g1118c2e05e67-1500000) (compatible with > GNU linkers) > > Its manual page also shows the -z option. So, for now, users can > use the option suppress the warning. It is not just FreeBSD. I opened a new PR 117455.
