Hi all,
As Christophe mentioned at
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg00202.html
These tests fail on big-endian. The reason is that the input is not
aligned to 128 bit forcing the use of a movmisalign which we don't
support on big-endian.
A solution is to force the alignment of the arrays, allowing for the use
of normal loads and stores.
We can look into enabling misaligned loads on big-endian with the
appropriate reversal logic as a separate
piece of work...
Ok for trunk?
