Thank you for your interest in the binutils. > Since I have been doing C language development for many years, is there any > plan to introduce disassembler's machine code instruction information > including the amount of clock cycles needed to execute? No. But it could be added. Although it would have to be architecture specific, and it may not be that useful since on many architectures the number of clock cycles taken by an instruction depends upon a variety of factors, not just the instruction itself. If you are interested in writing a patch for the binutils that implements such a feature we would be happy to review it - and answer questions you may have about how to do it. Cheers Nick
