| ; This test case checks whether the ARM DWARF stack frame directives |

| |
| ; We have to check several cases: |
| ; (1) arm with -disable-fp-elim |
| ; (2) arm without -disable-fp-elim |
| ; (3) armv7 with -disable-fp-elim |
| ; (4) armv7 without -disable-fp-elim |
| ; (5) thumb with -disable-fp-elim |
| ; (6) thumb without -disable-fp-elim |
| ; (7) thumbv7 with -disable-fp-elim |
| ; (8) thumbv7 without -disable-fp-elim |
| ; (9) thumbv7 with -no-integrated-as |
