FWIW, here is the exchange so far with a gcc developer about this:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19614

The good news is that with gcc's CVS head the amount of memory used during
this compile has gone down from 1.5G to 750M.  While that's still a lot of
memory, it's not that much more than x86 and as at least "in the ballpark"
of how much memory most developers might have. (IMO, of course.)

Take care,
