tqchen opened a new pull request, #19509: URL: https://github.com/apache/tvm/pull/19509
The TIR CSE pass currently lifts expressions like Cast(int32, 1) or Min(1, 2) into a cse_v binding when they appear twice, even though they are compile-time constants and provide no CSE benefit. This pollutes the IR with bindings of the form cse_v = 1. Extend CSEPlanner::IsEligible to reject any expression whose subtree contains no Var. -- This is an automated message from the Apache Git Service.
