Roman Lebedev b6a0e78067 [Value][InstCombine] Fix one-use checks in PHI-of-op -> Op-of-PHI[s] transforms to be one-user checks ... As FIXME said, they really should be checking for a single user, not use, so let's do that. It is not *that* unusual to have the same value as incoming value in a PHI node, not unlike how a PHI may have the same incoming basic block more than once. There isn't a nice way to do that, Value::users() isn't uniqified, and Value only tracks it's uses, not Users, so the check is potentially costly since it does indeed potentially involes traversing the entire use list of a value.		2020-08-26 20:20:41 +03:00
