Pixman Keeps On Pushing & Optimizing Pixels
Phoronix: Pixman Keeps On Pushing & Optimizing Pixels
Pixman 0.27.2 has been released and it offers up more features...
I wonder if there are still CPUs being used these days that don't have SSE, but do have MMX or that run the MMX codepath better than the SSE one... Is MMX still relevant?
The reason I was working on the MMX code paths were for Loongson and ARM/iwMMXt.

But they can't run pixman's MMX paths, because that's actually SSE-enhanced MMX, in layman terms
Does anyone actually use these?

Not a huge market share no, but they're used in thin clients / signage / point of sale / etc.
Btw, it's quite interesting to have these things happen, just like once the 486 patents expired 486 clones started appearing from non-intel-amd-via manufacturers. 586 and MMX are free to go now it seems, and we're seeing 1GHz low power cpus with those.
