In previous a[],b[],c[] are global arrays,
while they are local arrays,GCC works well.

Can you please post the flags you used and the full test?

Hi,
I unroll the following code one times in a gimpile pass.
for(i=0; i< N ; i++)
a[i] = b[i] + c[i];
And then I create the loops's ddg using build_intra_loop_deps ( ) in
an RTL pass;
I found the data dependence information: insn 54 TRUE_DEPENDENCE insn 53.
insn 50 (set (reg:SF 243) (mem/s
