> Memory usage building Firefox with debug enabled was reduced from 15GB to 3.5GB; link time from 1700 seconds to 350 seconds. This is huge- you can now do this on a laptop

well, you could do it on a laptop before, you just needed a much beefier laptop. But that's really impressive, how did they cut the resource usage to a quarter of previous usage?

GCC 4.9 hasn't yet been released (and won't be until after Easter). Currently there's only a release candidate. See http://permalink.gmane.org/gmane.comp.gcc.devel/135470

Interesting the main page http://gcc.gnu.org/ lists 4.9 as the current release as opposed to Development release.

I am very curious too. Such drastic improvements often indicates something wrong before (either in design or implementation) that got fixed.

Seems like competition from clang led to some really practical improvements.

I use whatever compiler is defined in the makefile or called for in a README. Needless to say I do not really follow developments in either camp closely. I am curious what improvements are the result of "competition" from clang?

If you follow the 4.9 link, you get to http://gcc.gnu.org/gcc-4.9/ which states:

> As of this time no releases of GCC 4.9 have yet been made.
