Guys,
allow me just one question. As a gcc user badly affected by slow c++
compilation and as a result not using gcc/g++ for any other development, I
really would like to see such patches somewhere. So my question is: where
and when they'll appear in some of gcc branches? Or are they just
available for download for 'brave' g++ user who can give them a try?
Thanks a lot,
Karel

Well, Mike just checked in a patch that provides a 33% speedup. On the
head, I've checked in several patches that improve performance by several
percent, and have more in the works. Nathan is working on a patch to
remove exponential (no, not just quadratic, exponential) behavior in the
C++ front end that has been there since *forever* -- probably 2.7.2.
Sigh, I have a patch that gives a 10x improvement on compile speed...
It makes template programming, fast. I think it rises up to the top of
work to get into the tree next, I think... The change is to ditch the
linked lists from the specializations, instantiations and mangling code.
