errors)

Tests fail on both 32 and 64-bit targets.

Does this target support atomics and multi-threaded at all?

do any tests in gcc/gcc.dg/atomic* run or are they all unsupported?

The target doesn't support atomics.  There is only only one atomic 
instruction (ldcw).

There is pthread and semaphore support.

gcc.dg/atomic-flag.c, gcc.dg/atomic-generic.c, gcc.dg/atomic-lockfree.c, 
gcc.dg/atomic-noinline-aux.c,
gcc.dg/atomic-noinline.c pass.  The remainder are unsupported

Actually, loads and stores are also atomic and strongly ordered.  But 
that's it.

Created attachment 26746
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26746
disable tests if no atomic support present

That test case really shouldn't be running.   To make sure we're on the right
track, add the line 

// { dg-require-atomic-builtins "" }

at the top of the test case (patch attached for the 2 you mention)  

Presumably it won't execute the test case anymore, thus avoiding the failure...
Can you give it a try?

Are those the only 2 failing?  interesting.
