Yes. It will be more ellegant and easier for compiler to remove following conditions, but
what about
+ static int reg_inc_found_and_valid_p (unsigned int, unsigned int, rtx);
In this case I must hide this under preprocessor too. I feared to overburden code by preprocessor
expressions.
What is you opinion?
