MICA counters for specific code block

[rjfnobre]

Is it possible to make MICA/PIN to measure between A and B?

In the following example what would I have to do (in terms of code instrumentation or parameters passed to MICA) so that the MICA counters would only be incremented for CODE BLOCK 2?

int main() {

// CODE BLOCK 1 // start measuring // CODE BLOCK 2 // end measurement // CODE BLOCK 3

}

Last time I used PIN was ages ago, but I think you can selectively enable instrumentation by injecting some PIN methods... @amirjamez?

Hi,

Sorry for the sluggish reply.

I haven't done this myself, but i believe you can use PIN's instrumentation features.

How about this? http://reverseengineering.stackexchange.com/questions/8884/how-can-i-remove-a-bbl-instrumentation-call-at-a-specific-address-in-pin#

Nevertheless, you should track the number of times the instrumentation is done, depending on the number of invocation of the block (calls) it has and I believe it might be a little noisy. As another workaround, you can make each of those blocks an independent executable object and use the native MICA feature to instrument the binary at run-time.

Hope either of them work.
