| ## 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 |
| ## .text |
| ## .globl _main |
| ## _main: |
| ## .cfi_startproc |
| ## .cfi_def_cfa_offset 16 |
| ## .cfi_endproc |
| ## nop |
| ## |
| ## llvm-mc -filetype=obj -triple=x86_64-apple-macos10.15 -o foo1.o foo.s |
| ## ld -r -o foo.o foo1.o |
| |
| # RUN: rm -rf %t; mkdir -p %t |
| # RUN: yaml2obj %s -o %t/foo.o |
| # RUN: %lld -o %t/a.out %t/foo.o |
