--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
For some reason the testcase doesn't fail on the branch. DOM dump:
Visiting PHI node: i_3 = PHI <0(2), _9(3)>
Argument #0 (2 -> 4 executable)
0: [0, 0]
Argument #1 (3 -> 4 executable)
_9: UNDEFINED
Meeting
[0, 0]
and
UNDEFINED
to
[0, 0]
LKUP STMT i_3 = PHI <0, _9>
2>>> STMT i_3 = PHI <0, _9>
<<<< STMT i_3 = PHI <0, _9>
Optimizing statement bb_5:
Optimizing statement return i_3;
so the singleton isn't extracted for some reason. The issue is still latent
of course.
