- kazinator 3y agoWhen I say that a variable is used, I mean that its value is accessed. This is in line with compiler jargon. In this basic block, the variable x has no next use at the first line; the assignment of 42 is a dead assignment. x = 42 y = w x = 43 Search the web for "next-use information".
