--- Comment #14 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
And yes it did start with r12-5300-gf98f373dd822b3 in the end. The reason is
before that we didn't allow this structure:
|
middle-bb -----|
| |
| |----| |
phi<1, 2> | |
cond | |
| | |
|--------+---|
That is before the middle-bb pred could only be the bb containing the cond.
While afterwards we allowed the middle having branches into it.
