ABI variants
Some architectures have binary-incompatible sub-architecture variants. Historic examples are non-executable stacks (handled with the GNU_STACK program header and the .note.GNU-stack section) and 16-byte stack alignment on i386 (which did not receive any markup).
Potential such changes are:
