Hi Richard,

Thanks for all of that.  I assume you will be taking care of upstreaming this?

FYI, I have been working on getting an old [glibc port][0] ready for 
upstreaming.
There still is a lot of testing and cleanup to be done.  But so far the work has
uncovered 2 bugs in OpenRISC binutils and gcc.  I cced you on both of those, did
you see them?

 - binutils (*) : https://sourceware.org/ml/binutils/2019-08/msg00214.html
 - gcc : https://gcc.gnu.org/ml/gcc-patches/2019-08/msg01549.html

* the binutils patch is already pushed upstream.
