I'm sorry for the confusion. What I meant was the assembly instructions added (to pass data values to Ruby) before the sethi instruction. For example, mov %0, %%g1. Do those instructions have a lot of impact on the outcome?
Thanks,
Denisse

Hence, I also do not understand Denisse's question.

I?m afraid that I missed your point in my previous reply. But I think the magic instruction doesn?t make any memory reference, does it? Dear List,
When I pass some data values from the user program to Ruby via magic instructions, does Simics forward those data references to Ruby? In other words, do those data references within magic instructions get profiled by Ruby? If so, is it possible to exclude those data references from Ruby profiling?
Thank you,
Denisse
