Hello, I want to mesure the number of cycles made by my code. So that, I implemented this code: double c; __asm (“rdhwr $2,$0 n” :”=r” (c): “0” (c)); printf(“Time is: %lf n “,c );
Yet, the result is usually :Time is: 0.000000.(gcc compiler is used). There is no way to use the mfc0 instruction with register 9, select 0? What should I change?
Thanks a lot!
