Provide x86-64-v2 optimizations

Open lemire opened this issue 1 year ago • 2 comments

Windows 11 version 24H2, Rocky Linux 9, RedHat Linux 9, all defaults on x86-64-v2 which means that we have SSSE3, SSE4.1, SSE4.2 and POPCNT. We might be able to include more optimizations for these cases.

Also since Windows 8 it's not boot without popcnt.

@IRainman We may not be able to support x86-64-v2 optimizations under Visual Studio because it does not set macros.

Having to do runtime dispatching might be too much for a header-only library.
