      1 ; ARM EHABI integrated test
      2 
      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
