Ah, I was thinking binary libraries from the trace points. But I missed you said C source code. But still, we need to build a way to convert big endian to little, as well as perhaps converting 32bit to 64 bit longs. As well as vice versa. We also need a way to export all structures (here ktime_t) as well as enums. Of course we need to export enums now anyway, since the tools don't know how to convert them now. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
