Deepti, if I understand your question correctly, you are asking for a tool that shows the dependencies within the compiler - or are you looking for something that will show the dependencies that source code (to be compiled by the compiler) have?

Compiler dependencies are usually libraries used to link. If you are building a compiler from source (like gcc), there are multiple system libraries that you need to have installed/compiled before you can do the compiler itself. If, you are asking about code dependencies (missing include files or libraries), 'make depend' - http://mad-scientist.net/make/autodep.html

Thanks for clearing this doubt on question. I actually wanted to know tools which shows the dependence exist in the source code (specially in loops).

Ok. I think I have a better understanding of what you're talking about now. If you have a loop (as you've mentioned), you would like to parallelize the loop execution - but need to know which variables (if any) will be accessed by each of the loops being executed in parallel.

Example (phony code, used as clarification purposes):

#pragma omp threadprivate result, alpha, beta

#pragma omp for

for (i=0; i < 10; i++) {

result[i] = alpha[i] * beta[i];

cxx = cxx + result[i];

}

In the example, variables result, alpha, and beta are isolated and usable in each thread simultaneously as you are referencing a different entry into each array. note that the variable cxx is where the problem occurs because you don't know what order the result array entries will be added in - or which value of cxx will be added to each time.

Yes, I tried OpenMP its good. I am also interested to know other tools similar to OpenMP.
