Now I see it, appreciate the clarification! At first I thought this was a memory address, but now I think these are the microops that build up the “inc” instruction.
Thanks for your help, Ferran!

For instance, look at this trace (slightly cropped to avoid useless information for the case): inc DS:[rbp + 0xfffffffffffffff8] INC_M : ldst t1, DS:[rbp + 0xfffffffffffffff8] : MemRead : D=0x0000000000079a8f A=0x7fffffffeb78 INC_M : addi t1, t1, 0x1 : IntAlu : D=0x0000000000000000 INC_M : st t1, DS:[rbp + 0xfffffffffffffff8] : MemWrite : D=0x0000000000079a90 A=0x7fffffffeb78 D is one of the operands, you can see how its value is incremented at the end of the operation.

I need to get the exact values of the operands not only the register names or addresses.

If I didn't understand you wrong, this is what you're looking for. Cheers, Ferran O.

I found that in the iew stage right before the instruction is sent for execution I have access to its physical register numbers, and the register accessor functions in dyn_inst may allow me to read its operands. I still need to print its final result though after it returns from execution, which I can probably do with two dumps, one before the call to execute and one after. Is there a more direct method I am missing on?
