; ARM EHABI integrated test
|
|
|
|
; This test case checks whether the ARM unwind directives are properly
|
|
; generated or not.
|
|
|
|
; The purpose of the test:
|
|
; (1) .fnstart and .fnend directives should wrap the function.
|
|
; (2) .setfp directive should be available if frame pointer is not eliminated.
|
|
; (3) .save directive should come with push instruction.
|
|
; (4) .vsave directive should come with vpush instruction.
|
|
; (5) .pad directive should come with stack pointer adjustment.
|
|
; (6) .cantunwind directive should be available if the function is marked with
|
|
; nounwind function attribute.
|
|
|
|
; 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
