            Bug ID: 61713
           Summary: 4.9 ICE when building c++ code with atomic functions
                    for thumb1 target
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tony.wang at arm dot com

The tool chain is built from:
gcc version 4.9.1 20140630 (prerelease) [gcc-4_9-branch revision 212159]
when compile below code, there will be ICE.
int main()
{
  typedef bool atomic_type;
  atomic_type c1;
  atomic_type c2;
  atomic_type c3(0);
  __atomic_fetch_add(&c1, c2, __ATOMIC_RELAXED);
  __atomic_compare_exchange_n(&c1, &c2, c3, true, __ATOMIC_ACQ_REL,
                              __ATOMIC_RELAXED);
  __atomic_test_and_set(&c1, __ATOMIC_RELAXED);
  __atomic_load_n(&c1, __ATOMIC_RELAXED);

  return 0;
}
Remember to save it as a c++ source file. For the debuggabe gcc, the ICE is:
at1.cpp: In function 'int main()':
at1.cpp:12:47: internal compiler error: in emit_move_insn, at expr.c:3609
__atomic_test_and_set(&c1, __ATOMIC_RELAXED);
