+; ARM EHABI integrated test

+; This test case checks whether the ARM DWARF stack frame directives
+; are properly generated or not.

+; We have to check several cases:

+; (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
