I'm not sure I understand what are you trying to do, but do you need
dynamic allocation? Can you define buffer offset on host side to correspond
to specific address you need? I haven't tried this but since e_alloc()
needs buffer offset to allocate memory from host side it should be fine.
But I don't know how will Epiphany see it.
About dynamic allocation - if you aren't already using stdlib on Epiphany
side, including it may take more memory than having unnecessary array
elements.
