toolchain64{,-libs} - 64-bit cross-compiling toolchain

gutmensch:
hehe yeah I know about most of the difficulties... even that PAE might work without doing anything at all ;)

but: 64 bit arch is needed sooner or later and I don't see any sense in still sticking with 32 bit, when it's possible to push the arch for the next 20 or 30 years and (despite of atom, netbook, etc.) this will be x64. I also think that most of the transition problems are relicts to old architecture features and not because x64 is slower in general ;)

so call me a hero.. I will give 15% system power away in order to bring x64 to the people, yaayy :D

coreplayer2:
Great tool thanks,  just in time for a build.

Am getting a "Upgrade your gcc" error  " -mcmodel=large not supported

??   needs an update already??    Please

Wait..  maybe I shouldn't have compiletc loaded at the same time..?

tinypoodle:
Errr...
Are you sure this is the subforum you meant to post this in?

coreplayer2:
Sure it is..   But I was compiling a 64bit application whilst other tools were loaded :(  so that was the error I'd got,   anyhow I figured out on my own.  My bad, but it's a gas right??
 

curaga:
The GCC 4.2 manpage states

--- Quote ---       -mcmodel=large
           Generate code for the large model: This model makes no assumptions
           about addresses and sizes of sections.  Currently GCC does not
           implement this model.

--- End quote ---

This mail: http://gcc.gnu.org/ml/gcc/2010-10/msg00321.html
says that mcmodel=large changes the ABI, and so you need to compile _everything_ with it. That seems quite unnecessary, what code wants that option?
