I imagine they have as much utility and direct hardware support as popcnt, clz and ctz.\r\n\r\nThey seem trivial to support, and increase the richness of the MVP, so I don't see why we would defer them.\r\n\r\nI created PR https://github.com/WebAssembly/spec/pull/149 for support in the spec interpreter.\r\n\r\nOf course, AstSemantics and other tools would need updating as well.\r\n\r\nWhat say all?"}}
