Hello,

This change
http://gcc.gnu.org/viewcvs?view=revision&revision=179689
removed references to gfc_loopinfo's codimen field and one conditional 
checking against gfc_loopinfo::dimen (as we had the convention that dimensions 
above dimen were codimensions).
I have noticed two more of those conditionals which I'm proposing for removal.

This is not a bug nor a regression, so this should normally wait for the next 
stage1. It is obvious on the other hand, and safe, as the 'n < loop->dimen' 
conditions are inside a 'for (n = 0; n < loop->dimen; n++)' loop.

Regression tested on x86_64-unknown-linux-gnu (with the just posted pr51250 
patch). OK for trunk?

	* trans-array.c (set_loop_bounds): Remove dead conditions.

OK. Thanks for the clean up.
