Re: [tree-ssa] Correct the initialization of an edge flag
During my try to reconcile the tree cfg with the rtl cfg, I found this
kind of small differences quite annoying. I'm not sure that sharing
code for the loop analysis/optimization is worth the worries. I'm sure
it will be faster to rewrite it at the tree level from scratch than trying
to make it work fine at both the rtl and tree level.
The main problem is that even the top level of the loop detection pass
has lots of the rtl specificities.
