Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2019-12-19 CC| |amker at gcc dot gnu.org, | |jakub at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- In r235513 when this was added the cost has been set only conditionally in the loop, and used unconditionally. But then r237552 made the cost computation in the loop unconditional, which made the subtraction before the loop useless.
