--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'm worried if this isn't too expensive, as there are just 3 dead_or_set_p uses
in define_split patterns in the compiler apparently, one in i386.md (the one
hitting in this and the other PR), guarded with reload_completed, and two for
movdi splitters in s390.md (not guarded by that). If the s390.md splitters
could be guarded by reload_completed, we could at least avoid the df_analyze in
split1 pass.
