--- Comment #4 from acsawdey at gcc dot gnu.org ---
At present trunk is vectorizing this in the vect pass not unrolling and
vectorizing in slp.
Code generated for mydata::Set is:
_ZN6mydata3SetEf:
.LFB4:
.cfi_startproc
xscvdpspn 1,1
li 9,16
xxspltw 0,1,0
stxvd2x 0,0,3
stxvd2x 0,3,9
blr
It seems like the test case should be looking for this alternative, I can't see
how a loop with a single stxvd2x that runs two iterations would be better.
