This doesn't build, you cannot assume the existence of "%ncc", it is a recent addition. Furthermore there is no need to ever use %ncc in v9 targetted code anyways. I'll fix that up, but this was a really disappointing build failure to hit. Meanwhile, two questions: 1) Is this also faster on T4 as well? If it is, we can just get rid of the T4 routines and use this on those chips as well. 2) There has been a lot of discussion and consideration put into how a memcpy/memset routine might be really great for the local cpu but overall pessimize performance for other cpus either locally on the same core (contention for physical resources such as ports to the store buffer and/or L3 cache) or on other cores. Has any such study been done into these issues wrt. this new code? -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
