I don't think think setting FPOptions in `ConditionalOperator` is a good idea. This operator does not represent any floating-point operation so setting FP properties on it does not look reasonable.

Instead, I would like to propose you using FPOptions from CompoundStmt, you could use the same code as in this PR: https://github.com/llvm/llvm-project/pull/89617/files#diff-6ddbe6b52b91cf337ee1b7c1ce6ced7d81882f749ac36c81d12714cb298319d6R568-R573
It was added just for similar cases.
