--- Comment #10 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Eric, I think the condition should be "!strict" rather than > "reload_in_progress". I'm not certain about that, but I think the patch > might fail if reload needs to iterate over insns more than once. I tried it, but this breaks in earlier RTL passes; we'll see in any case.
