The process of merging of the loop optimizer work I am currently doing
on rtlopt branch. I am quite sure that I won't be able to get it to
reasonable state for 3.4. I would however like to reuse some parts of
this work on tree-ssa. Would it be feasible to merge this work from
rtlopt branch to tree-ssa branch once it is in sufficiently stabilized
state (in about a month or so)?
Note that induction variable re-combination can only be done at the RTL
level, because only at that level it's clear what addressing modes are
available to estimate correct costs.
Cheers,
