Is there a particular need for generating while-loops?

Ya, for adding tasking constructs of OpenMP inside while statement.

We considered the question at the very beginning of implementing Csmith, and decided to use for-loops to represent all sorts of loops (while, do-while, etc.) which are different at the language level, but are normalized to the same form at the IR level. We believe generating both for-loops and while-loops would find marginally more bugs than just generating for-loops alone.

I started hacking Csmith for adding StatementWhile.h and
StatementWhile.cpp in Csmith.
I have made necessary changes in Makefile which builds the above files

I just need a pointer to

1. What changes do I need to make if I try cloning
    StatementFor.cpp ---------> StatementWhile.cpp
    StatementFor.h -------> StatementWhile.h ?

2. Which files do I need to check for adding the increment _expression_
in StatementWhile inside the body of a while statement ? Are there any
similar implementations which I can refer to?

3. Will the post_loop_analysis and visit_facts of StatementFor need
any changes to be made when used in StatementWhile ?

3. Any files which have dependencies apart from Statement* ?
