Thanks for trying it out.  Good to know.
It's just that the comment above movsf_ie...

;; We may not split the ry/yr/XX alternatives to movsi_ie, since
;; update_flow_info would not know where to put REG_EQUAL notes
;; when the destination changes mode.

sounds a bit scary.  However...

grep update_flow_info gcc/*

gcc/ChangeLog-1999:    (update_flow_info): Move to flow.c, renamed to
update_life_info;

That was quite a while ago... maybe it isn't a problem anymore.
