[Bug tree-optimization/19676] Loop optimizer fails to reverse simple loop

[pinskia at gcc dot gnu dot org]

Confirmed, we should be able to do this on the tree level but don't for testloop2, testloop3, testloop4.

To answer this question:
*  - why is gcc inconsistent in loop reversal bounds????
Because sometimes we do loop reversal on the tree level or the rtl level.  See above about where we 
don't do it on the tree level.

Do you know if all of these loops were loop reversal for say 3.4.0?
