Hello is there a efficient way of getting the number of executions between two instructions?

e.g.
Addr A: 0x4001000 push ebp // Set Break point here and run to Addr B
.
50,000 instructions in here including loops, branches, etc.
.
Addr B: 0x4500123 ret

I want to know if I can get the number 50,000 here somehow.
Of course, I can put break and trace at Addr A, and a bp at Addr B,
then count the number of entries in the trace. But that does not seem
very efficient.

Thank you.

In actuality, I have a program that loops and runs the same instruction at
Addr A a bunch of times, and I want to know approximately how many
instructions are within each loop. This number could vary, of course,
but I would like to get a rough estimate.
I have a problem that doesn't converge within 200k+ instructions, so
that's the problem I'm working with.

A lua script like this should be able to tell you how many instructions there are, but it won't tell you how many instructions are _run_. That's going to depend on the values used at run time so to figure out that you're going to actually have to run the code, which essentially means break and trace as far as I know (you can save the results to a file and then count certain lines, eg. how many EAX lines there are; In an editor like vim you can easily delete every line that doesn't start with EAX and then just use the line numbers to tell you how many instructions were executed)...

script to count instructions, tested in the lua engine (open the memory view(er) go to tools then lua engine) on the tutorial

hmm, check ultimap2
in there set a start and stop region, and make it output to a file . then parse that file

a: also jumps and loops (and conditional jums)

b: choose log directly to file.
it will hold all a list origin, destination and extra field

the problem with ultimap1 is that you can't set the start/stop region so it logs all branches in the target process. (including interrupts)
