It may be so ingrained in my brain that I'm not _always_ saying it when
talking about the large code model over a beer. And indeed I know of no
particular problems with it vis GCC, but that doesn't mean it's a good
idea to use :-)
So once again: "everyone should simply stop using -mcmodel=large. Noone
should use it."
So the patch goes strictly into the direction of betterment of the
universe. :)
Ciao,
Michael.
