Hi, You can extract the instruction's information anywhere in the pipeline from a DynInstPtr object. For example, you could find the instruction type by:
OpClass op_class = inst->opClass(); For floating point instructions, I think you should checkout the the vector instructions using XMM registers instead of FMUL. I dont knwo if gem5 implement the x87 instructions. On Thu, Apr 7, 2016 at 11:34 PM, dipesh ingawale <dipeshingaw...@gmail.com> wrote: > Hi All, > > I am new to the gem5.
