Remove need for SSE2 support #4

Open satta opened 8 years ago

satta commented 8 years ago

Currently the code in ksw.c seems to need SSE2 to compile. It would be nice to have some kind of -- probably slower -- fallback implementation to improve support on architectures without these instructions.

I need to revamp ksw.c at some point. It is in fact buggy in rare conner cases. Will add non-SSE implementation when that day comes.

Thanks!

As a stop-gap solution, you can use SSE2NEON to make it work on ARM by adding the header to the project and then applying this patch:
