How can LRA ever be made default for all targets without breaking those
that do not want to change?
LRA advocates would have to fix the issues with it that prevent it from
being usable on certain targets. Based on my initial experiments with
Blackfin, and LRA review comments I had based on c6x requirements, I
suspect register elimination will have to be rewritten to start with.
Do you have PR #s for those issues?
No. You can reproduce issues with Blackfin easily by enabling LRA for
it, and I described the C6X issues when the LRA patches were posted for
review.
