If you are experiencing or witnessing conflict, we ask you to use the following escalation strategy to address the conflict:

1.  Address the perceived conflict directly with those involved, preferably in a
    real-time medium.
2.  If this fails, get a third party (e.g. a mutual friend, and/or someone with
    background on the issue, but not involved in the conflict) to intercede.

			// names are disjoint and so can safely share a single namespace. However,
			// it's possible that a future update to the CSRs in inst.go could introduce
			// a conflict. This check ensures that such a conflict does not go
			// unnoticed.
			if _, ok := riscv64SpecialOperand[csrName]; ok {
				panic(fmt.Sprintf("riscv64 special operand %q redefined", csrName))
