[uClinux-dev] linux 2.6.x on Arcturus ColdFire uC5272

Then I'm very confused.  I'm being told that others build 2.6.x for the uC5272 using gcc 3.4.0.  Why can't I?  Is there a config option that doesn't build this offending code?  Or is there a patch to fix the asm code?

I don't think your doing anything wrong. That asm code looks
broken to me, there shounldn't be "%d0" in the clobber list
(function _bsc1 in include/asm-m68knommu/bootstd.h).

Newer versions of gcc are much more pedantic about this type
of thing, older compilers would have been happy with it.
