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; RUN: -disable-fp-elim -filetype=asm -o - %s \ 23;
