Subject Re: [dmlc/tvm] [RFC][PASS][RUNTIME] Enable Slice on LHS during concat (#2975)
Date Mon, 08 Apr 2019 20:35:07 GMT
Once you have liveness analysis, you could detect when some vars die on an instruction, while
another var is created. Let call it substitution. To optimize concat, we could detect substitution
on concat instruction, and extend the liveness of vars who previously die on this instruction.
