--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note, before *.ira the pseudo 93 set by the movsicc is actually used by another
insn, but that is removed early in the ira pass during
delete_trivially_dead_insns. But for some reason the if_then_else is not
removed as trivially dead, and even if it would, nothing recomputes the lr
problem (or is that live) that would adjust or reset the debug insns that are
refering the pseudos that are not live anymore.
