--- Comment #3 from luoxhu at gcc dot gnu.org ---

phiopt4 and sink2 are doing reverse optimizations:

pr102008.c.200t.phiopt4: 

 Hoisting adjacent loads from 3 and 4 into 2:  _6 = foo_4(D)->a;  _5 =
foo_4(D)->b;

pr102008.c.202t.sink2: 

 Sinking _5 = foo_4(D)->b; from bb 2 to bb 4
 Sinking  _6 = foo_4(D)->a; from bb 2 to bb 3
