Let me know if I need to expand on this. That suggestion is so funny to me that i'll let it stand here in its absurdity :) Did i get it right, you are suggesting for LTT to build a full SystemTap interpreter, an script-to-C compiler, an embedded-C script interpreter, just to be able to build-time generate the SystemTap scripts back into the source code? Dont you realize that you've just invented SystemTap, sans the ability to remove inactive code? ;) I know a much easier method: a "static tracer" can do all of that (and more), if you rename "SystemTap" to "static tracer" ;-) Ingo - 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/
