Hi, Evandro,

Sorry that it took so long for me to get back to you after the GCC
Summit.  I've been quite busy and couldn't focus on this issue for a
while.

Here's an updated patch the should address all of your concerns.  The
proposed ABI changes haven't changed at all for almost a year, and in
the mean time we've ported it to one more platform (ARM), so I believe
this is rock solid now.

Let me know what you think about the proposed changes.  They document
what's implemented in GNU binutils, GCC and the pending patches I have
for glibc, that I'm retesting after updating them to a current tree.

Thanks,
