I'm wondering if anyone has any information on the steps neccessary to try and build GCC 3.2 as a 64-bit compiler. I'm sure this will involve a recompile of Binutils and GCC, dunno about glibc, though. Judging by test compiles of the 2.4.20-pre6 kernel, something is broken in egcs64 that doesn't want to compile the 2.4.20-preX line, and whether this is fixable or not, I dunno.

I'd like to try GCC 3.2 as 64bit, maybe chip into Gentoo development and make an ebuild out of anything successful with it, I'm just not sure where to get started, and Google searches don't seem to turn up much information, except this one result: http://gcc.gnu.org/ml/gcc/2002-09/msg00116.html.

Hmmm..
If you plan to use a 64-bit version of gcc, please remember that the rest of your system needs to be compiled as 64-bit too. You can't easily mix and match unless there is support for doing so in the general libraries.

Don't try to compile 64-bit programs if you are running a 32-bit kernel. That's not going to work at all.

I'm aware of all of this. I was asking because egcs64 is a pretty out of date compiler...but it's apparently one of the only 64-bit GCC-class compilers out there. Linux kernel under sparc64 is built 64-bit by egcs64, but I was wonder if it is even remotely possible to build a gcc 3.2 64-bit cross compiler (I assume this is what would be needed, but again, I am not sure).
