Hi,
One of the loops in gcc/testsuite/gcc.dg/vect/vect-1.c is suspect. A
two-level nested loop in foo() uses the same index variable for both
loops, but uses a different variable to access the matrix inside the
loop. I presume this is a typo as this loop is expected to vectorize.
Attached is a patch that fixes this.
