--- Comment #4 from Kewen Lin <linkw at gcc dot gnu.org> ---
I can't reproduce this on ppc64le with both the default bootstrapping checking
option --enable-checking=yes,extra and the reported --enable-checking=release.
I'm going to test it on cfarm x86 machine.
If the error message lineno is correct, it complains on line 10962:
/* Collect vector loads and later create their permutation in
vect_transform_grouped_load (). */
if (!costing_p && (grouped_load || slp_perm))
dr_chain.quick_push (new_temp); // line 10962
It's guarded with !costing_p and we have:
/* One common place to cost the above vect load for different
alignment support schemes. */
if (costing_p)
{
...
}
else
{
vec_dest = vect_create_destination_var (scalar_dest,
vectype);
...
new_temp = make_ssa_name (vec_dest, new_stmt); // line 10911
...
}
at line 10911, new_temp is always initialized for !costing_p. It looks like a
false positive.
Anyway, I'll reproduce it first on x86.
