[photran] Fw:UnrollLoopRefactoring in Photran

[王春艳 <chunyanno1@xxxxxxx>]

Hello

I am running Eclipse IDE Indigo 3.7.2 version with Photran  7.0.7.201203231233.

When I use the UnRollLoopRefactoring provided, it will produce an error results.

The do loop example I used is as follows:

do i=1,10,2

   print *,i

   print *, i+1

end do

When do the numbered unrolling, if I set the unrolling count to 3, it will produce the following code:

    do i=1,10,6

        print *,i

        if(i+2>10) exit

        print *,(i+2)

        print *,(i+4)

    end do

Obviously it is not correct.

And when do completely unrolling, it will also generate similar error.

So I wonder if there is any bug in this UnrollLoopRefactoring itself when considering the loop boundary.

Thank you in advance.
