Issue #20464 has been updated by kddnewton (Kevin Newton). In that case this can probably be closed. ---------------------------------------- Bug #20464: Redundant returns are unreachable in coverage https://bugs.ruby-lang.org/issues/20464#change-108172 * Author: kddnewton (Kevin Newton) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- With the following code: ```ruby def meth_return(a) return if a return end ``` If you run coverage on it, it's not possible for it to hit line 3, because there isn't a line event, because the return node was eliminated from the AST before it was compiled. There is a `putnil` instruction, so it's possible for us to attach a line event for it, but the compiler doesn't today. -- https://bugs.ruby-lang.org/
