CallahanRL opened a new issue #8616: URL: https://github.com/apache/tvm/issues/8616
https://github.com/apache/tvm/blob/9f29e2a94923604aeff88d1a8f3efaf0c3bd0655/src/arith/rewrite_simplify.cc#L857 I have a counter example to this rewrite. It takes this code `floormod((((threadIdx.x*50) + (b.i.fused.j.fused.inner.outer.inner*8)) + b.i.fused.j.fused.inner.inner.s_1), 20)` to this code: `ramp((floormod(((threadIdx.x*50) + (b.i.fused.j.fused.inner.outer.inner*8)), 20)*32), 32, 8)` The code determines the modular set to have base 0 and coeff 2 but when it computes ramp_max for lanes=8, it incorrectly determines that ramp_min==ramp_max. Perhaps this is always a problem with ceoff*lanes < c2val? I can't provide a test case because it requires a modified version of vectorize_loop.cc which I can't yet share. cc @jcf94 @tqchen -- This is an automated message from the Apache Git Service.
