I might put 'current' into %g7 on sparc but currently I don't think it's worth it myself. BTW, your "4 issue" comments assume the cpu can do 4 non-FPU instructions per cycle, most I am aware of cannot and I think ia64 even falls into the "cannot" category. Doesn't it? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
