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 20 21 ; RUN: llc -mtriple arm-unknown-linux-gnueabi \ 22 ;
