The patch kit I posted here:
  https://gcc.gnu.org/ml/gcc-patches/2015-06/msg00116.html
gives about a 5x speedup (from about 50ms down to about 10ms on my box),
but parts of it are very invasive, so unlikely to be backported to the
gcc 5 branch.  *If* I get it in, it'll be a gcc 6 thing (hence perhaps
April 2016 in terms of an official release).

Is the compilation speed something you're looking at for Ravi?  What
kind of times are you seeing, and what were you hoping to see?

Dave
