Harder to vectorize 64-bit arithmetic?
- CorvusCrypto 10y agowas going to say this. It probably only does SSE and not SSE2. Therefore vectorization only happens for 32 bit ints.
- user2994cb 10y agoSeems to need -mavx2 to really go to town with 64 bit: https://godbolt.org/g/6EFYeY https://godbolt.org/g/6EFYeY
- jdcarter 10y agoThank you both, I appreciate the insight!
