Hello @DzAvril, Problem is related to splitting of TE expression onto
sub-areas, so having f(x1, ..., xk) as output is is a bit problematic to define
particular input tensor from x1,..., xk coordinates. Using hashing function
from the axis coordinates may require more intermediate memory.
Frankly speaking the concatenation price should be 0 in many cases but it
may require a lot of efforts to implement this solution because it will be
necessary to update whole SW stack within TVM.
