Thanks. Pushed to the binutils-2_35-branch.

January is before the GCC11 release, so that would be good.
I had hoped for a 2.35.2 release with just these fixes to make working
with (early) GCC11 DWARF5 support easier. Technically only the gas fix
is needed to work around some minor GCC11 bootstrap failure (the line
table might have an extra entry, that could be ignored, but the
bootstrap compare won't). But various tools use binutils readelf in
their testsuite and it would be nice if these fixes were picked up by
distros to make testing things easier. Personally even though I know I
need to use binutils trunk when working/testing DWARF5 I still forget
from time to time and am scratching my head till I remember I am using
the system binutils...

Cheers,
