   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
