Hi all,
Can we backport PR97969 patch to GCC 10 and (maybe) GCC 9 ?:

IMHO bug is severe and could land in GCC 10 and 9. Vladimir's original patch:
https://gcc.gnu.org/pipermail/gcc-patches/2021-January/563322.html
applies without changes to both gcc-10 and gcc-9.
I've regression tested this patch on both gcc-10 and gcc-9 branched for
x86_64 cross (arm-eabi target) and no issues.
OK for gcc-10 and gcc-9 ?
I see two fallout PRs with a trivial search: PR98643 and PR98722. LRA
patches quite easily trigger unexpected fallout unfortunately ...
Yes, I am agree. We should wait until the new regressions are fixed. I
am going to work on this patch more to fix the new regressions.Â
Although the basic idea of the original problem solution probably will
stay the same.
PS: I can commit if approved.
