Does it support application-wide counter?

I think, the counter starts from the first value at the beginning of each new translation unit, is it possible to use an incrementing counter application-wide? I want to have unique values between translation units either.
Do you think FILE macro (converted to an int value, in compile-time) helps?

Can you give me some context? Constant evaluation is always translation unit focused. If you want to make each translation unit fully independent I recommend adding an anonymous namespace in the unconstexpr headers or in your project.
This will make sure that each declaration / function / etc.. is only usable inside the translation unit and will not leak its state to other ones.

To access a global array by index from different TUs, I need to have a unique number even between TUs.
I want to keep hit count for specified statements like the following;

A.cpp
globArr[0]++;
globArr[1]++;
globArr[2]++;
globArr[3]++;

B.cpp
globArr[4]++;
globArr[5]++;
globArr[6]++;

Global.h
int globArr[7];

The workaround is having distinct arrays for each TUs, is there another way?
