If it's really undesirable to mention pointer integrity here, I think the main point can still be made with a phrase like Bruce proposed (but I think it's fine as it exists now). What about "In order to maximize compatibility with future changes in pointer size or representation, manipulation..."? Very briefly (to give some context), in CheriBSD and the CHERI CPU pointers are 128 or 256 bits wide, and have a base address, length, permissions, and other fields. Thus the size differs from existing standard integer types, and a pointer's representation and even the essence of what a pointer is differs from pointers in existing FreeBSD architectures. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
