[gem5-users] How to classify op_class for x86 macoops

2012-10-31 Thread Shen Yiran
Hi Ali, I am a new user of gem5. I want to classify the op_class for x86 . I searched in the archive, and I saw you answering the question corresponding to similar question. It seems this work is well done for ARM. But how could that be done for x86, and for the macroops. Thanks a lot. Cheers, -J

[gem5-users] Where is the source code for tracking program pointer?

2012-10-11 Thread Shen Yiran
Hi All, I am very new to computer architecture simulator and is looking into gem5. I want to track the program counter under SE mode. Although I can do that via debug options, I want to know where in the source code this work actually gets done. I am using the atomic simple cpu mode. I could not f

[gem5-users] X86 O3 instruction fetch problem

2012-10-25 Thread Shen Yiran
Hi All, I am looking into the fetching stage for X86 O3. I have one question. For ordinary PC advancing without prediction or branch, lets say the current PC is: 0x4120a4.0 while the nextPC associated with the same DynInst is 4120a5.1 Why the actual PC fetched next will be 0x4120a4.1 instead of 41
