| ; ARM EHABI integrated test |
| |
| ; This test case checks whether the ARM unwind directives are properly |
| ; generated or not. |
| |
| ; The purpose of the test: |
| ; (1) .fnstart and .fnend directives should wrap the function. |
| ; (2) .setfp directive should be available if frame pointer is not eliminated. |
| ; (3) .save directive should come with push instruction. |
| ; (4) .vsave directive should come with vpush instruction. |
| ; (5) .pad directive should come with stack pointer adjustment. |
| ; (6) .cantunwind directive should be available if the function is marked with |
| ; nounwind function attribute. |
| |
| ; 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 |
