# REQUIRES: x86
## 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
# RUN: llvm-objdump --macho --section-headers %t/a.out | FileCheck %s
# CHECK: __unwind_info {{.*}} DATA
