Are there any evidence of said bloat and poor performance with 4.0 or do you base it on hearsay? :-) I studied a lot of assembly output on the pre-release versions of 4.0 and the optimizer has really improved compared to the older series. I would imagine stuff not compiling is mostly because the C++ standard has moved considerably over the last years, and a lot of software which caters for GCC 2.95 isn't well-formed given the latest revision of the standard. That said, it usually takes a minor revision (i.e. 4.1) before a compiler is generally usable for a distro. I remember all the breakage when GCC 3.0 was introduced.. // Andreas -- gentoo-user@gentoo.org mailing list

The executables were around 70% larger and computation took around 50% longer. I am comparing with the results I achieved with GCC 3.4.3 using the same compiler flags in each case.

Re: [gentoo-user] GCC 4.0
I wouldn't recommend rebuilding your system with it. Apparently glibc needs to release a new version 2.3.6 to be compatible. Of course, since it's stricter than previous GCCs, it's probably a good idea to try compiling any software you write with it to make sure that it doesn't break in the future.
