Research direction
Start by comparing libaco, Tencent's libco v1.0, and hev-task-system against the existing libco usage in the repository. Profile the alternatives in the bsnes-mercury context, including the stated MMX/SSE/AVX preservation behavior, and document whether one should replace the current implementation.
Written by the indexing model from the issue text.
Description
I found a potential replacement for libco though I am not 100% sure as to the veracity of its claims:
https://github.com/hnes/libaco
Also found another library by Tencent:
https://github.com/Tencent/libco/tree/v1.0
and this:
https://github.com/heiher/hev-task-system
libaco claims to be the fastest cothread library, while also having support for saving/restoring MMX/SSE/AVX state on x86/x64, which iirc byuu's libco doesn't have. The changes compared to libco on resulting cores haven't been profiled, though personally I am quite intrigued in seeing if on bsnes-mercury it helps, if even minutely.
