# Test basics of debug_line parsing. This test uses a linker script which
# ensures the code is placed at the end of a module to test the boundary
# condition when the final end-of-sequence line table entry points to an address
# that is outside the range of memory covered by the module.
# REQUIRES: lld, x86
# RUN: llvm-mc -triple x86_64-pc-linux %s -filetype=obj > %t.o
# RUN: ld.lld --script=%S/Inputs/debug-line-basic.script %t.o -o %t
# RUN: %lldb %t -o "image dump line-table -v a.c" -o exit | FileCheck %s
