Performance problem

I'm investigatinga performance issue with a simple loop and am looking for the right events to monitor in VTune.

The problem with the loop is that the variables appear to be aliased so that the compiler cannot use a register variable. The solution is to use a local variable, how can VTune identify this problem inother places in my code?

Although VTune is capable to identify performance problems related to the microarchitecture on the level of generated by compiler code (by using statical analysis), the sort of problem youve described is not in the scope of the analisis. I believe a debugger better sutes for that.
