The first patch adds support for the m68k-linux syscall. The second
patch adds native support for the m680[2346]0 CAS instruction, and
the m68000/Coldfire TAS instruction.
Both tested only via cross-compile.
Please test...
Thanks Richard. I'm currently bootstrapping and regtesting this
natively on aranym.
Bootstrapped fine and tested mostly OK. Seems to have eliminated all
atomics-related regressions in 4.7-2012. Compared to 4.7-2005
I have the following test suite result changes:
