As for testing I've bootstrapped and tested the patch on aarch64 and

I don't have access to Sparc, you want Rainer here (added in Cc:).
As is, the patch doesn't even build on current mainline:
/vol/gcc/src/hg/trunk/local/gcc/tree-vect-patterns.c:2151:56: error:
'mult_variant' has not been declared

Ah, sorry I forgot to mention that this is patch 2/2.
It requires https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01144.html which is
already approved
but I was planning to commit it together with this one.
Can you please try applying
https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01144.html
as well as this?
Thanks,
Kyrill
