------- Comment #1 from pinskia at gcc dot gnu dot org 2008-08-24 22:04 -------
There are a couple of issues here I think. The first being that the loop:
for (j = 0; j < 4; j++)
arr[j] = mat2[i][j];
is not being unrolled.
If I specify -fpeel-loops, it is unrolled but then we don't SRA arr at all as
we unroll too late.
