Ping**2?
I'd like to get these patches committed, if possible, to clear up my

Slightly updated patch below, with a better test case as suggested
by Dominique.
OK for trunk?

It should return true, if the expression is known to be noncontiguous.

Hi Tobias,
Talking about dependencies, I wonder whether you would be interested
implementing the function
bool gfc_simply_noncontiguous (gfc_expr *);
or something similarly named.
If you will work on it, please tell me -
Sounds interesting. I'll give it a shot.

Thomas,
Your test gfortran.dg/dependency_40.f90 does not have depedencies and
does not create a temporary (assuming that -Warray-temporaries does
not miss any) with/without your patch and with gcc4.6, 4.7, and 4.8.
4.5 gives a warning. I have tried a few variants attempting to create
a temporary
Hello world,
below is a patch which improves dependency checking for array
assignments and calculation of string lengths.
The new function gfc_dep_difference is used for both. This allows
us to detect, for example, that the difference between the lower
indices of
a(n:m:2) = a(n+1:m+1:2)
