Hi,<div><br></div><div>I am working on Instruction prefetching, and wish to pre-fetch (insert intrinsic prefetch instruction) basic blocks based long before the branch operation is seen. I was thinking if there is any way of extracting the values used in the compare instruction, and going to there definition to speculate on the taken branch.</div>
<div><br></div><div>I would like to know if I can extract the values from the instruction, and go to their available/reaching definition.</div><div><br></div><div>Thanks!</div><div><br></div><div>Regards,</div><div>Silky Arora</div>
