--- Comment #5 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
The allocation is correct.  Simply there is no rebuilding conflicts after
generations moves on region edges (there are a lot of them, about 100) for LRA
as LRA does not need the conflict info from IRA.

The patch will be committed soon.
