| # 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: %lldb %t -o "image dump line-table -v a.c" -o exit | FileCheck %s |
