Hi Bradley, That's a good point. But also, what does "armv8a"

I wrote a proof of concept regarding the cpu capabilities runtime detection and choice of optimized function. I follow design which had been discussed on IRC. Also, i notice a little drawback: we must propagate the arch index through functions which don't have codec state as argument. However, if it's look good, i will continue to implement it.

There are a lot of old code out there, including the Linux kernel which we do care a lot, that only compiles with GAS. We're slowly moving the legacy code up to modern standards, and specifically some kernel folks are happy to move up
