This is a follow-up to #15864, which added
LegalizeOps
to the default Relax build pipeline. Since legalization may produce additional TIR PrimFuncs that require scheduling, the output ofLegalizeOps
typically must also be passed throughtir.transform.DefaultGPUSchedule()
. This PR addsDefaultGPUSchedule()
to the relax build pipeline to handle these cases.Scheduled PrimFunc have the
"tir.is_scheduled"
attribute set to true, and are ignored byDefaultGPUSchedule()
. In addition, theDefaultGPUSchedule
transform has no effect on non-GPU targets. Therefore, this change should only impacttvm.relax.build
calls that previously resulted in an error due to unscheduled GPU functions, and should not have any impact on existing calls.
