Oh, you’re great, thanks!

All of them have been applied in trunk?

OK, wonderful. I noticed genattrtab taking most of a day
since 4.4 or so…

>All three have been thoroughly regression-tested on multiple archs
>(m68k, armv5te, x86_64, sparc64, powerpc64).

OK, good to know.

A pointer couldn’t hurt, although I’d just submit that to
the GCC maintainer, since I’m currently concentrating on
4.6 and not even patching 4.7.
