Re: PATCH: [4.1/4.2 Regression]: Miscompiled FORTRAN program

What about defining the code this way:
#ifdef AUTO_INC_DEC

+ reg_inc_found_and_valid_p (unsigned int regno,

+                            rtx insn)
+ {

...
}
#else

#define reg_inc_found_and_valid_p(regno,endregno,insn) 0

#endif

So you can remove ugly ATTRIBUTE_UNUSED.

Thanks,

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?

Denis.
