It would be helpful for Adacore to contribute the support upstream
into the FSF tree, not only to make GNU Binutils more useful on AIX
but to avoid others duplicating your work -- especially in
incompatible ways.

The large TOC feature (cmodel=large) is not used by default and the
TLS feature is not enabled by default, so HEAD probably should
bootstrap with your private changes to Binutils. TLS tests for
assembler support, so that should fail with Binutils.

I had wanted your feedback about TLS within Ada before enabling the
configuration test by default, but that apparently will not be
possible with the way that Adacore's development model on AIX has

Thanks, David
