; 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:
; (1) arm with -disable-fp-elim
; (2) arm without -disable-fp-elim
; (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
