Hi Nikos, Thanks once again. I figured that out.
Can you help me in getting instruction trace for ALU ? I tried doing this for X86 system. What I am trying to do us to get instruction traces for ALU. What I did: There is a file, regop.isa (src/arch/x86/isa/microops/). In this file, at line 506, ADD function is defined. I tried to get the values of psrc1, op2 and DestReg, but I don’t think that these are instruction trace. I have attached a patch of results below: 2117728 8 2117736 27263459 0 27263459 2117736 8 2117744 29360611 0 29360611 2117744 8 2117752 31457763 0 31457763 2117752 8 2117760 33554915 0 33554915 2117760 8 2117768 35652067 0 35652067 2117768 8 2117776 37749219 0 37749219 2117776 8 2117784 39846371 0 39846371 2117784 8 2117792 2117792 8 2117800 2117800 8 2117808 2117808 8 2117816 2117816 8 2117824 2117824 8 2117832 2117832 8 2117840 2117840 8 2117848 The first column is for psrc1, second for op2 and third is for DestReg. If u notice every time the DestReg becomes psrc1 for next operation. And this kind of pattern is observed in complete traces. I don’t think this is the instruction trace for ALU. And I am not able to find where the ALU instructions are defined. I also tried getting traces from mediaop.isa (same folder), but sometimes traces are not at all generated. I don’t why. Any suggestions would a great help to me. Thanks in advance. Regards, Riddhi Sent from Mail for Windows 10
