llvm/lld/test/MachO/compact-unwind-sym-relocs.s

# 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
## .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
## ld -r -o foo.o foo1.o

# RUN: rm -rf %t; mkdir -p %t
# RUN: yaml2obj %s -o %t/foo.o
# RUN: %lld -dylib -lc++ %t/foo.o -o %t/foo
# RUN: llvm-objdump --macho --syms --unwind-info %t/foo | FileCheck %s
