Just FYI, we discovered that GNU binutils 2.17 has a nasty bug in the
linker that causes excessive link time when building llvm. We switched
to using cvs binutils and our link times went from minutes to seconds.
I didn't see anything about this on the web pages. It might be good
information to add to the Getting Started guide.

I don't know exactly when they went in. The "Linux binutils" apparently has the fix. I believe most Linux distributions supply that version. -Dave

The "Linux binutils" is essentially a pre-release version of the next GNU binutils and as such it can sometimes include less than optimal patches. Again, FYI. -Dave
