1; ARM EHABI integrated test

3; This test case checks whether the ARM DWARF stack frame directives
4; are properly generated or not.
5
6; We have to check several cases:
7; (1) arm with -disable-fp-elim
8; (2) arm without -disable-fp-elim
9; (3) armv7 with -disable-fp-elim
10; (4) armv7 without -disable-fp-elim
11; (5) thumb with -disable-fp-elim
12; (6) thumb without -disable-fp-elim
13; (7) thumbv7 with -disable-fp-elim
14; (8) thumbv7 without -disable-fp-elim
15; (9) thumbv7 with -no-integrated-as
