Hi
We have a bunch of memory arrays which are used as communication queues between
components. I want to count how much those queues are actually used by the
components by counting the memory accesses. This should be possible with
Valgrind, but it the actual tool has not been developed yet as far as I
researched. Maybe somewhere something similar was done already?
For clarification a little pseudo code:
int main() {
vector<int> a = init_a();
vector<Image> init_b();
foo(a, b);
bar(a, b);
}
void foo (&vector<int> a, &vector<Image> b) {
for (int i = 0; i < a.length; i+= 10)
a[i] = b[i/10].getRed(i);
}
void foo (&vector<int> a, &vector<Image> b) {
for (int i = 0; i < a.length; i+= 8)
if (a[i] == 42)
b[i%10].setTransparent();
}
The information I would like to get is something like:
Component Writes a Reads a Writes b Reads b
foo 243 27 574 235
bar 833 684 87 3897
The obvious challenges I can see is to identify/mark the components and memory
regions.
Mit freundlichen Grüßen / Best regards
