For a call site which had both constant deopt operands and nonnull arguments, we were missing the opportunity to recognize the later by bailing early. This is somewhat of a speculative fix. Months ago, I'd had a private report of performance and compile time regressions from the deopt operand folding. I never received a test case. However, the only possibility I see was that after that change CVP missed the nonnull fold, and we end up with a pass ordering/missed simplification issue. So, since it's a real issue, fix it and hope. |
