[PR] [TIR][SW] ensure non-overlap pipeline epilogue with prologue [tvm]
wrongtest-intellif opened a new pull request, #17579:
URL: https://github.com/apache/tvm/pull/17579
The MR try fix a corner case in software pipeline injection.
When the loop num is too few to fill the pipeline main body, the setup phase and draining phase's loop indices should not overlap. Currently the decomposition is
- prologue: [0, num_stage - 1)
- body: [num_stage - 1, loop_num)
- epilogue: [loop_num, loop_num+ num_stage - 1)
Thus we should also ensure that `i >= max(loop_num, num_stage - 1)` for epilogue part.
