--- Comment #8 from John David Anglin <danglin at gcc dot gnu.org> --- The change breaks bootstrap. See PR 117248. When the instructions to setup the argument registers for millicode calls are split out before reload, they sometimes are deleted. This affects SImode modsi3, umodsi3, divsi3 and udivsi3.
