--- Comment #8 from Iain Sandoe <iains at gcc dot gnu.org> ---
A secondary comment - the wiring up of the built-ins that allocate/deallocate
trampoline entries makes the underlying mechanism opaque to the middle end
consumer.
So, although the current example implementations use mmap / heap, I do not
believe that there is anything preventing an implementation from choosing some
alternate scheme for allocation of tables (e.g. a non-hosted impl could use a
fixed allocation - presumably with a hard fail if that allocation is exceeded.)
