any tool to count instructions?

hello guys,

i'm working on my computer architecture homework. of the tasks is to run a benchmark and count the top 20 mostly used instructions.

but i don't know what kind of tool can do that.

i know that AMD's codeanalyst has some thing called instruction-based sampling. but that doesn't work on my intel machine.

or is there any virtual machine that does this job?

thank you.

I'd assume if it's homework, your textbook and/or class notes should tell you how to get the information.

unfortunately it doesn't

i just found out that vtune will give that information.

Challenging question.

vtune gives an event based sampling test, which is similar to instruction count, but not exactly.

there is a tool, called simplescalar. but that thing is very stupid, it doesn't compile.
