Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|other |target --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- To not disrupt the ABI such parameters have to be copied in the callee to appropriately aligned stack slots or (with disrupting the ABI), passed by reference. I think separate bugs, one for each affected target, are appropriate here.
