Like fork and malloc, the ABI is a published, documented interface. I
think it's all right to depend on that.
The details of the function prologues emitted by GCC are not a public
interface, and are, again, a constant source of troubles.
I think it's okay to depend on the first, and I think it's a shame we
depend on the latter (even as I try to design mechanisms that will
help make that dependence less troublesome).
