Hi Vladimir,
I'll send V3 patchs based on these comments. Note that these four
patches only support subreg liveness tracking and apply to IRA and LRA
pass. Therefore, no performance changes are expected before we support
subreg coalesce. There will be new patches later to complete the
subreg coalesce functionality. Support for subreg coalesce requires
support for subreg copy i.e. modifying the logic for conflict detection.
Thank you for your clarification that the current batch of patches does
not change the performance. I hope the next batch of patches will be
added to devel/subreg-coalesce branch too for their easier evaluation.
