--- Comment #7 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- It's also related to PR rtl-opt/89862 because it's ultimately the synthesis of an integer constant in a register, which is not a word_register_operation_p, but here it's indirectly done by the mini-combiner in IRA thanks to the right combination of -fno-* options that prevents it from being done earlier as in most cases.
