I don't understand some of gcc-4.1-20070514, a patch here.

[J.C. Pizarro]

Hi developers,

for this http://gcc.gnu.org/ml/gcc/2007-05/msg00451.html

you have this nice cleanup's patch of gcc/loop.c that transliterates the logic
  of the uses of the loop_invariant_p (..) and consec_sets_invariant_p (..)
  functions.

I've patched it, builded and executed, and again again with this patched gcc.
It's OK.

It will be more readable and comprehensible. I did patch the comprehension!

To the expert person only, please, read now the loop algorithms that
uses *_OF_LOOP_P if there is any failed logic or not.

Sincerely yours, J.C.
