1; ARM EHABI integrated test
2
3; This test case checks whether the ARM unwind directives are properly
4; generated or not.
5
6; The purpose of the test:
7; (1) .fnstart and .fnend directives should wrap the function.
8; (2) .setfp directive should be available if frame pointer is not eliminated.
9; (3) .save directive should come with push instruction.
10; (4) .vsave directive should come with vpush instruction.
11; (5) .pad directive should come with stack pointer adjustment.
12; (6) .cantunwind directive should be available if the function is marked with
13;     nounwind function attribute.
14
15; We have to check several cases:
16; (1) arm with -disable-fp-elim
17; (2) arm without -disable-fp-elim
18; (3) armv7 with -disable-fp-elim
19; (4) armv7 without -disable-fp-elim
