| ## Test that we correctly handle symbol relocations in the compact unwind |
| ## section. |
| |
| ## llvm-mc does not emit such relocations for compact unwind, but `ld -r` does. |
| ## As such, these yaml files were from an object file produced with 'ld -r', |
| ## specifically: |
| ## |
| ## // foo.s |
| ## .globl _foo |
| ## .text |
| ## .p2align 2 |
| ## _foo: |
| ## .cfi_startproc |
| ## .cfi_personality 155, ___gxx_personality_v0 |
| ## .cfi_lsda 16, _exception0 |
| ## .cfi_def_cfa_offset 16 |
| ## ret |
| ## .cfi_endproc |
| ## |
| ## .section __TEXT,__gcc_except_tab |
| ## _exception0: |
| ## .space 0 |
| ## |
| ## llvm-mc -filetype=obj -triple=x86_64-apple-macos10.15 -o foo1.o foo.s |
