Hi Vladimir,
The following patch is necessary for porting avr to LRA.
The patch was successfully bootstrapped and tested on x86-64, aarch64, and
ppc64le.
There is still avr poring problem with reloading of subreg of frame
pointer. I'll address it later on this week.
this patch most likely broke sparc-sun-solaris2.11 bootstrap:

This is in stage 3. I haven't investigated further yet.
Thank you for reporting this. I'll try to fix on this week. I have a
patch but unfortunately bootstrap is too slow. If the patch does not
work, I'll revert the original patch.
