--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- (char) _2 1 times scalar_stmt costs 4 in body (char) _1 1 times scalar_stmt costs 4 in body (char) _6 1 times scalar_stmt costs 4 in body (char) _5 1 times scalar_stmt costs 4 in body those are in the end free, but I'm not sure how we could easily see that.
