[Bug tree-optimization/42916] [4.5 Regression] "-fcompare-debug failure" with "-O1 -funroll-loops -ftree-vectorize"



------- Comment #4 from rguenth at gcc dot gnu dot org  2010-02-19 13:40 -------
The difference is in alignment and some part of a patch of mine seems to
fix it ...

-(insn 230 229 231 3 t.i:5 (set (reg/v:SI 383 [ h ])
-        (mem/c/i:SI (symbol_ref:DI ("seed")  <var_decl 0x7ffff5aed000 seed>)
[0
 seed+0 S4 A128])) -1 (nil))
+(insn 567 566 568 3 t.i:5 (set (reg/v:SI 383 [ h ])
+        (mem/c/i:SI (symbol_ref:DI ("seed")  <var_decl 0x7ffff5af1000 seed>)
[0
 seed+0 S4 A32])) -1 (nil))
