Hi Alan,
Thanks for this patch. I see that you tested it on gcc110, which is a
big-endian platform. I think the pattern for V4SF might have an endian
problem on little-endian, but I'm not positive just eyeballing it. (I
think that the select of element 3 will address the wrong end of the
vector for LE.) Can you please try the patch on gcc112 as well to set
my mind at ease?
Thanks,
Bill

I think you are right....I'm just retesting without the patch to rule out other
test setup problems etc., but I see more tests failing on gcc112 than I expect
(comparing against e.g.
https://gcc.gnu.org/ml/gcc-testresults/2015-09/msg01479.html).
What's the best way to determine endianness - is it BYTES_BIG_ENDIAN, would that
be true on gcc110 but false on gcc112?
Cheers, Alan
