Just something else I saw while analyzing dumps from an unrelated set of
changes.
It's relatively common to see sequences like this:
# parent_1 = PHI
_11 = single_tree_10(D) != 0;
_12 = parent_1 == 0B;
_13 = _11 & _12;
if (_13 != 0)
goto ;
else
goto ;

Just something else I saw while analyzing dumps from an unrelated set of
changes.
It's relatively common to see sequences like this:
# parent_1 = PHI
_11 = single_tree_10(D) != 0;
_12 = parent_1 == 0B;
_13 = _11 & _12;
if (_13 != 0)
goto ;
else
goto ;
